vtls: remove obsolete declarations of SSL backend functionality

2017-08-28T12:56:57+00:00

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).

vtls: move the SUPPORT_HTTPS_PROXY flag into the Curl_ssl struct

2017-08-28T12:56:56+00:00

That will allow us to choose the SSL backend at runtime.

vtls: convert the have_curlssl_* constants to runtime flags

2017-08-28T12:56:56+00:00

The entire idea of introducing the Curl_ssl struct to describe SSL
backends is to prepare for choosing the SSL backend at runtime.

To that end, convert all the #ifdef have_curlssl_* style conditionals
to use bit flags instead.

vtls: move sha256sum into the Curl_ssl struct

2017-08-28T12:56:56+00:00

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.

vtls: move md5sum into the Curl_ssl struct

2017-08-28T12:56:56+00:00

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

2017-08-28T12:56:56+00:00

This is the first step to unify the SSL backend handling. Now all the
SSL backend-specific functionality is accessed via a global instance of
the Curl_ssl struct.

vtls: declare Curl_ssl structs for every SSL backend

2017-08-28T12:56:56+00:00

The idea of introducing the Curl_ssl struct was to unify how the SSL
backends are declared and called. To this end, we now provide an
instance of the Curl_ssl struct for each and every SSL backend.
