transports: ssh: replace deprecated function `libssh2_session_startup`
The function `libssh2_session_startup` has been deprecated since libssh2
version 1.2.8 in favor of `libssh2_session_handshake` introduced in the
same version. libssh2 1.2.8 was released in April 2011, so it is already
seven years old. It is available in Debian Wheezy, Ubuntu Trusty and
CentOS 7.4, so the most important and conservative distros already have
it available. As such, it seems safe to just use the new function.

transports: ssh: disconnect session before freeing it
The function `ssh_stream_free` takes over the responsibility of closing
channels and streams just before freeing their memory, but it does not
do so for the session. In fact, we never disconnect the session
ourselves at all, as libssh2 will not do so itself upon freeing the
structure. Quoting the documentation of `libssh2_session_free`:
> Frees all resources associated with a session instance. Typically
> called after libssh2_session_disconnect_ex,
The missing disconnect probably stems from a misunderstanding what it
actually does. As we are already closing the TCP socket ourselves, the
assumption was that no additional disconnect is required. But calling
`libssh2_session_disconnect` will notify the server that we are cleanly
closing the connection, such that the server can free his own resources.
Add a call to `libssh2_session_disconnect` to fix that issue.

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.

transports: ssh: clean up after libssh2 on exit
After calling `libssh2_init`, we need to clean up after the library by

ssh: store error message immediately after a failed agent call
When the call to the agent fails, we must retrieve the error message
just after the function call, as other calls may overwrite it.
As the agent authentication is the only one which has a teardown and
there does not seem to be a way to get the error message from a stored
error number, this tries to introduce some small changes to store the
error from the agent.
Clearing the error at the beginning of the loop lets us know whether the
agent has already set the libgit2 error message and we should skip it,
or if we should set it.

When the stream writing function was written, it assume that
libssh2_channel_write() would always write all of the data to the

fit into one ssh packet.
Since it can perform short writes, call it in a loop like we do for
send(), advancing the buffer offset.

ssh: make sure to ask for a username and use the same one
In order to know which authentication methods are supported/allowed by
the ssh server, we need to send a NONE auth request, which needs a
username associated with it.
Most ssh server implementations do not allow switching the username
between authentication attempts, which means we cannot use a dummy
username and then switch. There are two ways around this.
The first is to use a different connection, which an earlier commit
implements, but this increases how long it takes to get set up, and
without knowing the right username, we cannot guarantee that the
list we get in response is the right one.
The second is what's implemented here: if there is no username specified
in the url, ask for it first. We can then ask for the list of auth
methods and use the user's credentials in the same connection.

cred: tighten username rules
The ssh-specific credentials allow the username to be missing. The idea
being that the ssh transport will then use the username provided in the
url, if it's available. There are two main issues with this.
The credential callback already knows what username was provided by the
url and needs to figure out whether it wants to ask the user for it or
it can reuse it, so passing NULL as the username means the credential
callback is suspicious.
The username provided in the url is not in fact used by the
transport. The only time it even considers it is for the user/pass
credential, which asserts the existence of a username in its
constructor. For the ssh-specific ones, it passes in the username stored
in the credential, which is NULL. The libssh2 macro we use runs strlen()
against this value (which is no different from what we would be doing
ourselves), so we then crash.
As the documentation doesn't suggest to leave out the username, assert
the need for a username in the code, which removes this buggy behavior
and removes implicit state.
git_cred_has_username() becomes a blacklist of credential types that do
not have a username. The only one at the moment is the 'default' one,
which is meant to call up some Microsoft magic.
