vtls: remove obsolete declarations of SSL backend functionality
These functions are all available via the Curl_ssl struct now, no need
to declare them separately anymore.
As the global declarations are removed, the corresponding function
definitions are marked as file-local. The only two exceptions here are
Curl_mbedtls_shutdown() and Curl_polarssl_shutdown(): only the
declarations were removed, there are no function definitions to mark
file-local.
Please note that Curl_nss_force_init() is *still* declared globally, as
the only SSL backend-specific function, because it was introduced
specifically for the use case where cURL was compiled with
`--without-ssl --with-nss`. For details, see f3b77e561 (http_ntlm: add
support for NSS, 2010-06-27).

The _shutdown() function calls the _session_free() function; While this
is not a problem now (because schannel.h declares both functions), a
patch looming in the immediate future with make all of these functions
file-local.
So let's just move the _session_free() function's definition before it
is called.

The connect_finish() function (like many other functions after it) calls
the Curl_axtls_close() function; While this is not a problem now

The SHA-256 checksumming is also an SSL backend-specific function.
Let's include it in the struct declaring the functionality of SSL
backends.
In contrast to MD5, there is no fall-back code. To indicate this, the
respective entries are NULL for those backends that offer no support for
SHA-256 checksumming.

The MD5 summing is also an SSL backend-specific function. So let's
include it, offering the previous fall-back code as a separate function
now: Curl_none_md5sum(). To allow for that, the signature had to be
changed so that an error could be returned from the implementation
(Curl_none_md5sum() can run out of memory).

vtls: use the Curl_ssl struct to access all SSL backends' functionality

vtls: declare Curl_ssl structs for every SSL backend
The idea of introducing the Curl_ssl struct was to unify how the SSL

This new struct is similar in nature to Curl_handler: it will define the

This patch adds the new `libcurl` option `CURLOPT_SSH_COMPRESSION`

is required that the SSH server supports a (zlib) compatible

- Rename `Curl_pgrsResetTimesSizes` to `Curl_pgrsResetTransferSizes`
