transport: see if cert/cred callbacks exist before calling them
Custom transports may want to ask libgit2 to invoke a configured
credential or certificate callback; however they likely do not know if a
callback was actually configured. Return a sentinal value
(GIT_PASSTHROUGH) if there is no callback configured instead of crashing.

smart transport: only clear url on hard reset
After creating a transport for a server, we expect to be able to call
`connect`, then invoke subsequent `action` calls. We provide the URL to
these `action` calls, although our built-in transports happen to ignore
it since they've already parsed it into an internal format that they
intend to use (`gitno_connection_data`).
In ca2eb4608243162a13c427e74526b6422d5a6659, we began clearing the URL
field after a connection, meaning that subsequent calls to transport
`action` callbacks would get a NULL URL, which went undetected since the
builtin transports ignore the URL when they're already connected
(instead of re-parsing it into an internal format).
Downstream custom transport implementations (eg, LibGit2Sharp) did
notice this change, however.
Since `reset_stream` is called even when we're not closing the
subtransport, update to only clear the URL when we're closing the
subtransport. This ensures that `action` calls will get the correct URL
information even after a connection.

treewide: remove use of C++ style comments
C++ style comment ("//") are not specified by the ISO C90 standard and
thus do not conform to it. While libgit2 aims to conform to C90, we did
not enforce it until now, which is why quite a lot of these
non-conforming comments have snuck into our codebase. Do a tree-wide
conversion of all C++ style comments to the supported C style comments
to allow us enforcing strict C90 compliance in a later commit.

smart: don't dereference a NULL pkt pointer
By clarifying what detect_caps returns on empty/missing packet, we can
be sure there are actually refs to process. The old code could blindly
dereference `first`, which might have been NULL.

refspec: rename `git_refspec__free` to `git_refspec__dispose`
Since commit 630a67366 (refspec: add public parsing api, 2018-02-07), we
now have two functions `git_refspec_free` and `git_refspec__free`. The
difference is that the first one will free the structure itself, while
the second one will only free the structure's contents. Use our new
`dispose` naming pattern for the latter function to help avoid
confusion.

Make sure to always include "common.h" first
Next to including several files, our "common.h" header also declares
various macros which are then used throughout the project. As such, we
have to make sure to always include this file first in all
implementation files. Otherwise, we might encounter problems or even
silent behavioural differences due to macros or defines not being
defined as they should be. So in fact, our header and implementation
files should make sure to always include "common.h" first.
This commit does so by establishing a common include pattern. Header
files inside of "src" will now always include "common.h" as its first
other file, separated by a newline from all the other includes to make
it stand out as special. There are two cases for the implementation
files. If they do have a matching header file, they will always include
this one first, leading to "common.h" being transitively included as
first file. If they do not have a matching header file, they instead
include "common.h" as first file themselves.
This fixes the outlined problems and will become our standard practice
for header and source files inside of the "src/" from now on.

transport: provide a getter for the proxy options
As with the callbacks, third-party implementations of smart subtransports cannot
reach into the opaque struct and thus cannot know what options the user set.
Add a getter for these options to copy the proxy options into something external

smart: store reported symrefs
The protocol has a capability which allows the server to tell us which
refs are symrefs, so we can e.g. know which is the default branch.
This capability is different from the ones we already support, as it's
not setting a flag to true, but requires us to store a list of
refspec-formatted mappings.
This commit does not yet expose the information in the reference
listing.

Remove converting user error to GIT_EUSER
This changes the behavior of callbacks so that the callback error
code is not converted into GIT_EUSER and instead we propagate the
return value through to the caller. Instead of using the
giterr_capture and giterr_restore functions, we now rely on all
functions to pass back the return value from a callback.
To avoid having a return value with no error message, the user
can call the public giterr_set_str or some such function to set
an error message. There is a new helper 'giterr_set_callback'
that functions can invoke after making a callback which ensures
that some error message was set in case the callback did not set
one.
In places where the sign of the callback return value is
meaningful (e.g. positive to skip, negative to abort), only the
negative values are returned back to the caller, obviously, since
the other values allow for continuing the loop.
The hardest parts of this were in the checkout code where positive
return values were overloaded as meaningful values for checkout.
I fixed this by adding an output parameter to many of the internal
checkout functions and removing the overload. This added some
code, but it is probably a better implementation.
There is some funkiness in the network code where user provided
callbacks could be returning a positive or a negative value and
we want to rely on that to cancel the loop. There are still a
couple places where an user error might get turned into GIT_EUSER
there, I think, though none exercised by the tests.

Further EUSER and error propagation fixes
This continues auditing all the places where GIT_EUSER is being
returned and making sure to clear any existing error using the
new giterr_user_cancel helper. As a result, places that relied
on intercepting GIT_EUSER but having the old error preserved also
needed to be cleaned up to correctly stash and then retrieve the
actual error.
Additionally, as I encountered places where error codes were not
being propagated correctly, I tried to fix them up. A number of
those fixes are included in the this commit as well.

remote: make _ls return the list directly
The callback-based method of listing remote references dates back to the
beginning of the network code's lifetime, when we didn't know any
better.
We need to keep the list around for update_tips() after disconnect() so
let's make use of this to simply give the user a pointer to the array so
they can write straightforward code instead of having to go through a
callback.

Support cancellation in push operation
This commit adds cancellation for the push operation. This work consists of:
1) Support cancellation during push operation
- During object counting phase
- During network transfer phase
- Propagate GIT_EUSER error code out to caller
2) Improve cancellation support during fetch
- Handle cancellation request during network transfer phase
- Clear error string when cancelled during indexing
3) Fix error handling in git_smart__download_pack
Cancellation during push is still only handled in the pack building and
network transfer stages of push (and not during packbuilding).
