Since we already use the base64 package since a while back, we can just
as well switch to that here too.
It also happens to use the exact same function name, which otherwise
causes a run-time warning.

`USE_WINDOWS_SSPI` without `USE_WIN32_CRYPTO` but with any other DES
backend is fine, but was excluded before.
This also fixes test 1013 as the condition for SMB support in
configure.ac didn't match the condition in the source code. Now it
does.

The Schannel builds are the most useful to verify as they make the most
use of the Windows API. Classic MinGW doesn't support Unicode at all,
only MinGW-w64 and MSVC do.

poll and select already return -1 on error according to POSIX,
so there is no need to perform a <0 to -1 conversion in code.
Also we can just use one check with <= 0 on the return code.

Setting a timeout to INT_MAX could cause an immediate error to get
returned as timeout because of an overflow when different values of
'now' were used.
This is primarily fixed by having Curl_pgrsTime() return the "now" when
TIMER_STARTSINGLE is set so that the parent function will continue using
that time.

USE_TLS_SRP will be true if *any* selected TLS backend can use SRP
HAVE_OPENSSL_SRP is defined when OpenSSL can use it
HAVE_GNUTLS_SRP is defined when GnuTLS can use it
Clarify in the curl_verison_info docs that CURL_VERSION_TLSAUTH_SRP is
set if at least one of the supported backends offers SRP.

The get_cert_location function allocates memory only on success.
Previously get_cert_location was able to allocate memory and return

Check readiness of all sockets before waiting on them
to avoid locking in case the one-time event FD_WRITE
was already consumed by a previous wait operation.

Closes#5634
This avoids using a pair of TCP ports to provide wakeup functionality
for every multi instance on Windows, where socketpair() is emulated
using a TCP socket on loopback which could in turn lead to socket
resource exhaustion.
A previous version of this patch failed to account for how in WinSock,
FD_WRITE is set only once when writing becomes possible and not again
until after a send has failed due to the buffer filling. This contrasts
to how FD_READ and FD_OOB continue to be set until the conditions they
refer to no longer apply. This meant that if a user wrote some data to
a socket, but not enough data to completely fill its send buffer, then
waited on that socket to become writable, we'd erroneously stall until
their configured timeout rather than returning immediately.
This version of the patch addresses that issue by checking each socket
we're waiting on to become writable with select() before the wait, and
zeroing the timeout if it's already writable.

Change Curl_socket_check to use select-fallback in Curl_poll

This commit changes Curl_socket_check to use POLLPRI to
check for connect failure on the write socket, because
POLLPRI maps to fds_err. This is in line with select(2).
The select-based socket check correctly checks for connect
failures by adding the write socket also to fds_err.
The poll-based implementation (which internally can itself
fallback to select again) did not previously check for
connect failure by using POLLPRI with the write socket.
See the follow up commit to this for more information.
This commit makes sure connect failures can be detected
and handled if HAVE_POLL_FINE is defined, eg. on msys2-devel.
