The subtransport path was relying on pointing to data owned by
the remote which meant that after a redirect, the updated path
was getting lost for future requests. This updates the http
transport to strdup the path and maintain its own lifetime.
This also pulls responsibility for parsing the URL back into the
http transport and isolates the functions that parse and free that
connection data so that they can be reused between the initial
parsing and the redirect parsing.
9e9aee6 added an include <netinet/in.h> to fix the build on FreeBSD.
Sometime since then the same header is included ifndef _WIN32, so
remove the duplicate include.
W/o this a libgit2 error message could have a mixed encoding:
e.g. a filename in UTF-8 combined with a native Windows error message
encoded with the local code page.

According to man 3 SSL_shutdown / TLS, "If a unidirectional shutdown is
enough (the underlying connection shall be closed anyway), this first
call to SSL_shutdown() is sufficient."
Currently, an unidirectional shutdown is enough, since
gitno_ssl_teardown is called by gitno_close only. Do so to avoid further
errors (by misbehaving peers for example).
Fixes#1129.
3f9eb1e introduced support for SSL certificates issued for IP
addresses, making use of in_addr and in_addr6 structs. On FreeBSD
these are defined in (a file included in) <netinet/in.h>, so include
that file on FreeBSD and get the build working again.
SSL_get_error() allows to receive a result code for various SSL
operations. Depending on the return value (see man (3) SSL_get_error)
there might be additional information in the OpenSSL error queue. Return
the queued message if available, otherwise set an error message
corresponding to the return code.
Passing SSL_VERIFY_PEER makes OpenSSL shut down the connection if the
certificate is invalid, without giving us a chance to ignore that
error. Pass SSL_VERIFY_NONE and call SSL_get_verify_result if the user
wanted us to check.
When no CNs match, we used to jump to on_error which gave a bogus
error as that's for OpenSSL errors. Jump to cert_fail so we tell the
user that the error came from checking the certificate.
This allows us to add capabilitites to both at the same time, keeps
them in sync and removes a lot of code.
gitno_buffer now uses a callback to fill its buffer, allowing us to
use the same interface for git and http (which uses callbacks).
