In the ongoing endeavor to abstract out all SSL backend-specific
functionality, this is the next step: Instead of hard-coding how the
different SSL backends access their internal data in getinfo.c, let's
implement backend-specific functions to do that task.
This will also allow for switching SSL backends as a runtime option.

There are convenient no-op versions of the init/cleanup functions now,
no need to define private ones for axTLS.

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
(because axtls.h declares the latter function), a patch looming in the
immediate future with make all of these functions file-local.
So let's just move the Curl_axtls_close() function's definition before
it is called.

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.

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.
Signed-off-by: Johannes Schindelin <johannes.schindelin@gmx.de>
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).

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.

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
functions and capabilities of all the SSL backends (where Curl_handler

Recent changes that replaced CURL_SIZEOF_LONG in the source with
SIZEOF_LONG broke builds that use the premade configuration files and
don't have SIZEOF_LONG defined.
Bug: https://github.com/curl/curl/issues/1816
libidn was replaced with libidn2 last year in configure.
Caveat: libidn2 may depend on a list of further libs.
These can be manually specified via CURL_LDFLAG_EXTRAS.

Closes#1808
Since curl 7.55.0, NetworkManager almost always failed its connectivity
check by timeout. I bisected this to 5113ad04 (http-proxy: do the HTTP
CONNECT process entirely non-blocking).
This patch replaces !Curl_connect_complete with Curl_connect_ongoing,
which returns false if the CONNECT state was left uninitialized and lets
the connection continue.

The required low-level logic was already available as part of
`libssh2` (via `LIBSSH2_FLAG_COMPRESS` `libssh2_session_flag()`[1]
option.)
This patch adds the new `libcurl` option `CURLOPT_SSH_COMPRESSION`
(boolean) and the new `curl` command-line option `--compressed-ssh`
to request this `libssh2` feature. To have compression enabled, it
is required that the SSH server supports a (zlib) compatible
compression method and that `libssh2` was built with `zlib` support
enabled.

This change does two things:
1. It un-breaks the build in Xcode 9.0. (Xcode 9.0 is currently
failing trying to compile connectx() in lib/connect.c.)
2. It finally weak-links the connectx() function, and falls back on
connect() when run on older operating systems.
Update the progress timers `t_nslookup`, `t_connect`, `t_appconnect`,
`t_pretransfer`, and `t_starttransfer` to track the total times for
these activities when a redirect is followed. Previously, only the times
for the most recent request would be tracked.
Related changes:
- Rename `Curl_pgrsResetTimesSizes` to `Curl_pgrsResetTransferSizes`
now that the function only resets transfer sizes and no longer
modifies any of the progress timers.
- Add a bool to the `Progress` struct that is used to prevent
double-counting `t_starttransfer` times.
Added test case 1399.
