The WHILE_FALSE construction is used to avoid compiler warnings in
macro constructions. This fixes a few instances where it was not
used in order to keep the code consistent.

Given that this is performed by the NTLM code there is no need to
perform the initialisation in the HTTP layer. This also keeps the
initialisation the same as the SASL based protocols and also fixes a
possible compilation issue if both NSS and SSPI were to be used as
multiple SSL backends.

The regexp looking for assignments within conditions was too greedy
and matched a too long string in the case of multiple conditionals
on the same line. This is basically only a problem in single line
macros, and the code which exemplified this was essentially:
do { if((x) != NULL) { x = NULL; } } while(0)
..where the final parenthesis of while(0) matched the regexp, and
the legal assignment in the block triggered the warning. Fix by
making the regexp less greedy by matching for the tell-tale signs
of the if statement ending.
Also remove the one occurrence where the warning was disabled due
to a construction like the above, where the warning didn't apply
when fixed.

ERR_error_string(NULL) should never be called. It places the error in a
global buffer, which is not thread-safe. Use ERR_error_string_n with a
local buffer instead.

Attempt to unpause a busy read in the CURLOPT_XFERINFOFUNCTION.
When uploading from stdin in non-blocking mode, a delay in reading
the stream (EAGAIN) causes curl to pause sending data
(CURL_READFUNC_PAUSE). Prior to this change, a busy read was
detected and unpaused only in the CURLOPT_WRITEFUNCTION handler.
This change performs the same busy read handling in a
CURLOPT_XFERINFOFUNCTION handler.

This commit adds curl_multi_wakeup() which was previously in the TODO
list under the curl_multi_unblock name.
On some platforms and with some configurations this feature might not be
available or can fail, in these cases a new error code
(CURLM_WAKEUP_FAILURE) is returned from curl_multi_wakeup().

Prior to this change schannel ignored --tls-max (CURL_SSLVERSION_MAX_
macros) when --tlsv1 (CURL_SSLVERSION_TLSv1) or default TLS
(CURL_SSLVERSION_DEFAULT), using a max of TLS 1.2 always.

- Disable the extra sensitivity except in debug builds (--enable-debug).
- Improve SYSCALL error message logic in ossl_send and ossl_recv so that
"No error" / "Success" socket error text isn't shown on SYSCALL error.
Prior to this change 0ab38f5 (precedes 7.67.0) increased the sensitivity
of OpenSSL's SSL_ERROR_SYSCALL error so that abrupt server closures were
also considered errors. For example, a server that does not send a known
protocol termination point (eg HTTP content length or chunked encoding)
_and_ does not send a TLS termination point (close_notify alert) would
cause an error if it closed the connection.
To be clear that behavior made it into release build 7.67.0
unintentionally. Several users have reported it as an issue.
Ultimately the idea is a good one, since it can help prevent against a
truncation attack. Other SSL backends may already behave similarly (such
as Windows native OS SSL Schannel). However much more of our user base
is using OpenSSL and there is a mass of legacy users in that space, so I
think that behavior should be partially reverted and then rolled out
slowly.
This commit changes the behavior so that the increased sensitivity is
disabled in all curl builds except curl debug builds (DEBUGBUILD). If
after a period of time there are no major issues then it can be enabled
in dev and release builds with the newest OpenSSL (1.1.1+), since users
using the newest OpenSSL are the least likely to have legacy problems.

Closes https://github.com/curl/curl/pull/4623
Starting with this change when doing parallel transfers, without this
option set, curl will prefer to create new transfers multiplexed on an
existing connection rather than creating a brand new one.
--parallel-immediate can be set to tell curl to prefer to use new
connections rather than to wait and try to multiplex.
libcurl-wise, this means that curl will set CURLOPT_PIPEWAIT by default
on parallel transfers.

- s/USE_CYASSL/USE_WOLFSSL/
- Remove old compatibility macros.
Follow-up to 1c6c59a from several months ago when CyaSSL named symbols
were renamed to wolfSSL. The wolfSSL library was formerly named CyaSSL
and we kept using their old name for compatibility reasons, until
earlier this year.
Prior to this change:
The check if an extra wait is necessary was based not on the
number of extra fds but on the pointer.
If a non-null pointer was given in extra_fds, but extra_nfds
was zero, then the wait was skipped even though poll was not
called.
