Give callers the ability to select how to handle redirects - either
supporting redirects during the initial connection (so that, for

or all/no redirects. This is for compatibility with git.

remote: introduce `git_remote_connect_options`
The existing mechanism for providing options to remote fetch/push calls,
and subsequently to transports, is unsatisfactory. It requires an
options structure to avoid breaking the API and callback signatures.
1. Introduce `git_remote_connect_options` to satisfy those needs.
2. Add a new remote connection API, `git_remote_connect_ext` that will
take this new options structure. Existing `git_remote_connect` calls
will proxy to that. `git_remote_fetch` and `git_remote_push` will
proxy their fetch/push options to that as well.
3. Define the interaction between `git_remote_connect` and fetch/push.
Connect _may_ be called before fetch/push, but _need not_ be. The
semantics of which options would be used for these operations was
not specified if you specify options for both connect _and_ fetch.
Now these are defined that the fetch or push options will be used
_if_ they were specified. Otherwise, the connect options will be
used if they were specified. Otherwise, the library's defaults will
be used.
4. Update the transports to understand `git_remote_connect_options`.
This is a breaking change to the systems API.

str: introduce `git_str` for internal, `git_buf` is external
libgit2 has two distinct requirements that were previously solved by
`git_buf`. We require:
1. A general purpose string class that provides a number of utility APIs
for manipulating data (eg, concatenating, truncating, etc).
2. A structure that we can use to return strings to callers that they
can take ownership of.
By using a single class (`git_buf`) for both of these purposes, we have
confused the API to the point that refactorings are difficult and
reasoning about correctness is also difficult.
Move the utility class `git_buf` to be called `git_str`: this represents
its general purpose, as an internal string buffer class. The name also
is an homage to Junio Hamano ("gitstr").
The public API remains `git_buf`, and has a much smaller footprint. It
is generally only used as an "out" param with strict requirements that
follow the documentation. (Exceptions exist for some legacy APIs to
avoid breaking callers unnecessarily.)
Utility functions exist to convert a user-specified `git_buf` to a
`git_str` so that we can call internal functions, then converting it
back again.

Set Host Header to match CONNECT authority target
Prior to this change, for CONNECT requests, the Host header was set to
the host and port of the target http proxy. However, per the rfc7230 for
HTTP/1.1 this is incorrect as the Host header should match the target of
the CONNECT request, as detailed in section 5.3.3 & 5.4.
5.3.3. authority-form
The authority-form of request-target is only used for CONNECT
requests (Section 4.3.6 of [RFC7231]).
authority-form = authority
When making a CONNECT request to establish a tunnel through one or
more proxies, a client MUST send only the target URI's authority
component (excluding any userinfo and its "@" delimiter) as the
request-target. For example,
CONNECT www.example.com:80 HTTP/1.1
5.4. Host
<snip>
A client MUST send a Host header field in all HTTP/1.1 request
messages. If the target URI includes an authority component, then a
client MUST send a field-value for Host that is identical to that
authority component, excluding any userinfo subcomponent and its "@"
delimiter (Section 2.7.1). If the authority component is missing or
undefined for the target URI, then a client MUST send a Host header
field with an empty field-value.
This issue was noticed when proxying requests through HAProxy 2.2 which
rejects these invalid http requests.

winhttp: skip certificate check if unable to send request
In some circumstances (e.g. when proxies are involved), winhttp will fail to reach the WINHTTP_CALLBACK_STATUS_SENDING_REQUEST phase. If this occurs, we'll error with ERROR_WINHTTP_INCORRECT_HANDLE_STATE when attempting to query the server certificate context (see https://docs.microsoft.com/en-us/windows/win32/api/winhttp/nf-winhttp-winhttpsendrequest#remarks).
To avoid this, verify that WinHttpSendRequest has reached the WINHTTP_CALLBACK_STATUS_SENDING_REQUEST phase before checking the certificate. Since we're using WinHTTP in synchronous mode, we know for sure that once WinHttpSendRequest returns we've either sent it successfully or not.
NOTE: WINHTTP_CALLBACK_STATUS_SENDING_REQUEST appears to be deprecated with no direct replacement. WINHTTP_CALLBACK_STATUS_SENDREQUEST_COMPLETE is only available in async mode, and there doesn't appear to be a method of querying this flag outside of the status callback.

Don't fail if a HTTP server announces he supports a protocol upgrade
cf. RFC7230 section 6.7, an Upgrade header in a normal response merely informs the client that the server supports upgrading to other protocols, and the client can ask for such an upgrade in a later request. The server requiring an upgrade is via the 426 Upgrade Required response code, not the mere presence of the Upgrade response header.

httpclient: only free challenges for current_server type
Prior to this commit we freed both the server and proxy auth challenges
in git_http_client_read_response. This works when the proxy needs auth
or when the server needs auth, but it does not work when both the proxy
and the server need auth as we erroneously remove the server auth
challenge before we have added them as server credentials. Instead only
remove the challenges for the current_server type.

tree-wide: do not compile deprecated functions with hard deprecation
When compiling libgit2 with -DDEPRECATE_HARD, we add a preprocessor
definition `GIT_DEPRECATE_HARD` which causes the "git2/deprecated.h"
header to be empty. As a result, no function declarations are made
available to callers, but the implementations are still available to
link against. This has the problem that function declarations also
aren't visible to the implementations, meaning that the symbol's
visibility will not be set up correctly. As a result, the resulting
library may not expose those deprecated symbols at all on some platforms
and thus cause linking errors.
Fix the issue by conditionally compiling deprecated functions, only.
While it becomes impossible to link against such a library in case one
uses deprecated functions, distributors of libgit2 aren't expected to
pass -DDEPRECATE_HARD anyway. Instead, users of libgit2 should manually
define GIT_DEPRECATE_HARD to hide deprecated functions. Using "real"
hard deprecation still makes sense in the context of CI to test we don't
use deprecated symbols ourselves and in case a dependant uses libgit2 in
a vendored way and knows it won't ever use any of the deprecated symbols
anyway.

httpclient: clear the read_buf on new requests
The httpclient implementation keeps a `read_buf` that holds the data
in the body of the response after the headers have been written. We
store that data for subsequent calls to `git_http_client_read_body`. If
we want to stop reading body data and send another request, we need to
clear that cached data.
Clear the cached body data on new requests, just like we read any
outstanding data from the socket.

ensure that we do not read more than the client requests.

httpclient: read_body should return 0 at EOF
When users call `git_http_client_read_body`, it should return 0 at the
end of a message. When the `on_message_complete` callback is called,
this will set `client->state` to `DONE`. In our read loop, we look for
this condition and exit.
Without this, when there is no data left except the end of message chunk
(`0\r\n`) in the http stream, we would block by reading the three bytes
off the stream but not making progress in any `on_body` callbacks.
Listening to the `on_message_complete` callback allows us to stop trying
to read from the socket when we've read the end of message chunk.

httpclient: use a 16kb read buffer for macOS
Use a 16kb read buffer for compatibility with macOS SecureTransport.
SecureTransport `SSLRead` has the following behavior:
1. It will return _at most_ one TLS packet's worth of data, and
2. It will try to give you as much data as you asked for
This means that if you call `SSLRead` with a buffer size that is smaller
than what _it_ reads (in other words, the maximum size of a TLS packet),
then it will buffer that data for subsequent calls. However, it will
also attempt to give you as much data as you requested in your SSLRead
call. This means that it will guarantee a network read in the event
that it has buffered data.
Consider our 8kb buffer and a server sending us 12kb of data on an HTTP
Keep-Alive session. Our first `SSLRead` will read the TLS packet off
the network. It will return us the 8kb that we requested and buffer the
remaining 4kb. Our second `SSLRead` call will see the 4kb that's
buffered and decide that it could give us an additional 4kb. So it will
do a network read.
But there's nothing left to read; that was the end of the data. The
HTTP server is waiting for us to provide a new request. The server will
eventually time out, our `read` system call will return, `SSLRead` can
return back to us and we can make progress.
While technically correct, this is wildly ineffecient. (Thanks, Tim
Apple!)
Moving us to use an internal buffer that is the maximum size of a TLS
packet (16kb) ensures that `SSLRead` will never buffer and it will
always return everything that it read (albeit decrypted).

transports: http: fix custom headers not being applied
In commit b9c5b15a7 (http: use the new httpclient, 2019-12-22), the HTTP
code got refactored to extract a generic HTTP client that operates
independently of the Git protocol. Part of refactoring was the creation
of a new `git_http_request` struct that encapsulates the generation of
requests. Our Git-specific HTTP transport was converted to use that in
`generate_request`, but during the process we forgot to set up custom
headers for the `git_http_request` and as a result we do not send out
these headers anymore.
Fix the issue by correctly setting up the request's custom headers and
add a test to verify we correctly send them.

credential: change git_cred to git_credential
We avoid abbreviations where possible; rename git_cred to
git_credential.
In addition, we have standardized on a trailing `_t` for enum types,
instead of using "type" in the name. So `git_credtype_t` has become
`git_credential_t` and its members have become `GIT_CREDENTIAL` instead
of `GIT_CREDTYPE`.
Finally, the source and header files have been renamed to `credential`
instead of `cred`.
Keep previous name and values as deprecated, and include the new header
files from the previous ones.

http: send probe packets
When we're authenticating with a connection-based authentication scheme
(NTLM, Negotiate), we need to make sure that we're still connected
between the initial GET where we did the authentication and the POST
that we're about to send. Our keep-alive session may have not kept
alive, but more likely, some servers do not authenticate the entire
keep-alive connection and may have "forgotten" that we were
authenticated, namely Apache and nginx.
Send a "probe" packet, that is an HTTP POST request to the upload-pack
or receive-pack endpoint, that consists of an empty git pkt ("0000").
If we're authenticated, we'll get a 200 back. If we're not, we'll get a
401 back, and then we'll resend that probe packet with the first step of
our authentication (asking to start authentication with the given
scheme). We expect _yet another_ 401 back, with the authentication
challenge.
Finally, we will send our authentication response with the actual POST
data. This will allow us to authenticate without draining the POST data
in the initial request that gets us a 401.

httpclient: support expect/continue
Allow users to opt-in to expect/continue handling when sending a POST
and we're authenticated with a "connection-based" authentication
mechanism like NTLM or Negotiate.
If the response is a 100, return to the caller (to allow them to post
their body). If the response is *not* a 100, buffer the response for
the caller.
HTTP expect/continue is generally safe, but some legacy servers
have not implemented it correctly. Require it to be opt-in.

httpclient: support authentication
Store the last-seen credential challenges (eg, all the
'WWW-Authenticate' headers in a response message). Given some
credentials, find the best (first) challenge whose mechanism supports
these credentials. (eg, 'Basic' supports username/password credentials,
'Negotiate' supports default credentials).
Set up an authentication context for this mechanism and these
credentials. Continue exchanging challenge/responses until we're
authenticated.

httpclient: consume final chunk message
When sending a new request, ensure that we got the entirety of the
response body. Our caller may have decided that they were done reading.
If we were not at the end of the message, this means that we need to
tear down the connection and cannot do keep-alive.
However, if the caller read all of the message, but we still have a
final end-of-response chunk signifier (ie, "0\r\n\r\n") on the socket,
then we should consider that the response was successfully copmleted.
If we're asked to send a new request, try to read from the socket, just
to clear out that end-of-chunk message, marking ourselves as
disconnected on any errors.

httpclient: introduce a simple http implementation
Introduce a new http client implementation that can GET and POST to
remote URLs.
Consumers can use `git_http_client_init` to create a new client,
`git_http_client_send_request` to send a request to the remote server
and `git_http_client_read_response` to read the response.
The http client implementation will perform the I/O with the remote
server (http or https) but does not understand the git smart transfer
protocol. This allows us to split the concerns of the http subtransport
from the actual http implementation.

gssapi: protect GSS_ERROR macro
The GSS_ERROR(x) macro may expand to `(x & value)` on some
implementations, instead of `((x) & value)`. This is the case on macOS,
which means that if we attempt to wrap an expression in that macro, like
`a = b`, then that would expand to `(a = b & value)`.
Since `&` has a higher precedence, this is not at all what we want, and
will set our result code to an incorrect value. Evaluate the expression
then test it with `GSS_ERROR` independently to avoid this.

http: avoid generating double slashes in url
Prior to this change, given a remote url with a trailing slash,
such as http://localhost/a/, service requests would contain a
double slash: http://localhost/a//info/refs?service=git-receive-pack.
Detect and prevent that.
Updates #5321

smart_pkt: fix overflow resulting in OOB read/write of one byte
When parsing OK packets, we copy any information after the initial "ok "
prefix into the resulting packet. As newlines act as packet boundaries,
we also strip the trailing newline if there is any. We do not check
whether there is any data left after the initial "ok " prefix though,
which leads to a pointer overflow in that case as `len == 0`:
if (line[len - 1] == '\n')
--len;
This out-of-bounds read is a rather useless gadget, as we can only
deduce whether at some offset there is a newline character. In case
there accidentally is one, we overflow `len` to `SIZE_MAX` and then
write a NUL byte into an array indexed by it:
pkt->ref[len] = '\0';
Again, this doesn't seem like something that's possible to be exploited
in any meaningful way, but it may surely lead to inconsistencies or DoS.
Fix the issue by checking whether there is any trailing data after the
packet prefix.
