These functions do nothing useful when used with a non-ancient
version of openssl (namely 1.1.0 or above).

Its existence is a remnant of (libavcodec's) lock-manager API
which has been removed in a04c2c707d.
There is no need to use the same lock for avisynth, chromaprint
or tls, so switch to ordinary static mutexes instead.

There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

Print every error in the stack, if more than one, and don't print
bogus errors if there's none logged within OpenSSL.
Retain the underlying IO error code, print an error message out of
it, and pass the error code on to the caller.

It avoids leaving dangling pointers behind in memory.
Also remove redundant checks for whether the URLContext to be closed is
already NULL.

They have been removed altogether without a compat implementation, and are
either no-ops or return NULL.
This fixes compiler warnings about checks always evaluating to false, and leaks
of allocated mutexes.

It's completely absurd that libavcodec would care about libavformat
locking, but it was there because the lock manager was in libavcodec.
This is more stright forward. Changes ABI, but we don't require ABI
compatibility currently.
The rtmp protocol uses nonblocking reads, to poll for incoming
messages from the server while publishing a stream.
Prior to 94599a6de3 and
d13b124eaf, the tls protocol
handled the nonblocking flag, mostly as a side effect from not
using custom IO callbacks for reading from the socket. When custom
IO callbacks were taken into use in
d15eec4d6b, the handling of a nonblocking
socket wasn't necessary for the default blocking mode any longer.
The code was simplified, since it was overlooked that other code
within libavformat actually used the tls protocol in nonblocking mode.
This fixes publishing over rtmps, with the openssl backend.

TLS is currently implemented over either OpenSSL or GnuTLS, with more
backends likely to appear in the future. Currently, those backend libraries
are part of the protocol names used during e.g. the configure stage of a
build. Hide those details behind a generically-named declaration for the
TLS protocol to avoid leaking those details into the configuration stage.
The use of TLSv1_*_method() disallows newer protocol versions; instead
use SSLv23_*_method() and then explicitly disable the deprecated
protocol versions which should not be supported.

Fixes ticket #5915.
When the macro is expanded with a semicolon following it and the
macro itself contains a semicolon, we ended up in double semicolons,
which is treated as a statement that disallows further declarations.
This avoids errors about mixed declarations and statements on gcc,
after ee05079766.

Instead of a linked list constructed at av_register_all(), store them
in a constant array of pointers.
Since no registration is necessary now, this removes some global state
from lavf. This will also allow the urlprotocol layer caller to limit
the available protocols in a simple and flexible way in the following
commits.
Move the OpenSSL and GnuTLS implementations to their own files. Other
than the connection code (including options) and some boilerplate, no
code is actually shared.
