NTLM: use DES_set_key_unchecked with OpenSSL
... as the previously used function DES_set_key() will in some cases
reject using a key that it deems "weak" which will cause curl to
continue using the unitialized buffer content as key instead.

CURLOPT_PREREQFUNCTION: add new callback
Triggered before a request is made but after a connection is set up

Changes:

- callback: Update docs and callback for pre-request callback
- Add documentation for CURLOPT_PREREQDATA and CURLOPT_PREREQFUNCTION,
- Add redirect test and callback failure test
- Note that the function may be called multiple times on a redirection
- Disable new 2086 test due to Windows weirdness

60738f398c vtls: Fix a memory leak if an SSL session cannot be added to the cache
On connection shutdown, a new TLS session ticket may arrive after the
SSL session cache has already been destructed. In this case, the new
SSL session cannot be added to the SSL session cache.

The callers of Curl_ssl_addsessionid() need to know whether the SSL
session has been added to the cache. If it has not been added, the
reference counter of the SSL session must not be incremented, or memory
used by the SSL session must be freed. This is now possible with the new
output parameter "added" of Curl_ssl_addsessionid().

739de69ee6 libssh2: Get the version at runtime if possible
Previously this code used a compile time constant, meaning that libcurl
always reported the libssh2 version that libcurl was built with. This
could differ from the libssh2 version actually being used. The new code
uses the CURL_LIBSSH2_VERSION macro, which is defined in ssh.h. The
macro calls the libssh2_version function if it is available, otherwise
it falls back to the compile time version.

http: fix the broken >3 digit response code detection

the response to be non-compliant.

b0eda8dc6e strerror: use sys_errlist instead of strerror on Windows
- Change Curl_strerror to use sys_errlist[errnum] instead of strerror to
  retrieve the error message on Windows.

Windows' strerror writes to a static buffer and is not thread-safe.

Follow-up to 2f0bb86 which removed most instances of strerror in favor
of calling Curl_strerror (which calls strerror_r for other platforms).

hsts: handle unlimited expiry
When setting a blank expire string, meaning unlimited, curl would pass
TIME_T_MAX to getime_r() when creating the output, while on 64 bit
systems such a large value cannot be convetered to a tm struct making
curl to exit the loop with an error instead. It can't be converted
because the year it would represent doesn't fit in the 'int tm_year'
field!

Starting now, unlimited expiry is instead handled differently by using a
human readable expiry date spelled out as "unlimited" instead of trying
to use a distant actual date.

Test 1660 and 1915 have been updated to help verify this change.

ftp,imap,pop3,smtp: reject STARTTLS server response pipelining
If a server pipelines future responses within the STARTTLS response, the

error.

http2: Curl_http2_setup needs to init stream data in all invokes
Thus function was written to avoid doing multiple connection data
initializations, which is fine, but since it also initiates stream
related data it is crucial that it doesn't skip those even if called
again for the same connection. Solved by moving the stream
initializations before the "doing-it-again" check.
