Added support for checking the tchar, unicode and mbcs variants of
strcat() and strncat() in the banned function list.

Now giving credit properly to github user names, fixed some UTF-8 issues
and added names discovered when contrithanks was improved.

Prior to this change if a GitHub contributor's real name was unknown
they would be omitted from the list.

- Free compression methods if OpenSSL 1.0.2 to avoid a memory leak.

Bug: https://github.com/curl/curl/issues/817


Reported-by:  <jveazey@users.noreply.github.com>

While compiling lib/curl_multibyte.c with '-DUSE_WIN32_IDN' etc. I was
getting:

f:\mingw32\src\inet\curl\lib\memdebug.h(38): error C2054: expected '('
to follow 'CURL_EXTERN'

f:\mingw32\src\inet\curl\lib\memdebug.h(38): error C2085:
'curl_domalloc': not in formal parameter list

The connect-to list isn't copied so as long as the handle may be used
for a transfer the list must be valid.

See OpenSSL commit 21e001747d4a

... when generating them, not "2.0" as the protocol is called just
HTTP/2 and nothing else.

The preprocessor check that sets up the 32bit defines for non-configure
builds didn't work properly for MIPS systems as __mips__ is defined for
both 32bit and 64bit. Now __LP64__ is also checked and indicates 64bit.

For the Windows XP toolset of Visual C++ 2013/2015, the old Windows SDK
7.1 is used. In this case, _USING_V110_SDK71_ is defined.

...as otherwise the TLS libs will skip the CN/SAN check and just allow
connection to any server. curl previously skipped this function when SNI
wasn't used or when connecting to an IP address specified host.

CID 1361815: Explicit null dereferenced (FORWARD_NULL)

CID 1361811: Explicit null dereferenced (FORWARD_NULL)

CID 1024412: Memory - illegal accesses (OVERRUN). Claimed to happen when
we run over 'workend' but the condition says <= workend and for all I
can see it should be safe. Compensating for the warning by adding a byte
margin in the buffer.

Also, removed the extra brace level indentation in the code and made it
so that 'workend' is only assigned once within the function.

- Return value type must match function type.

Caught by Travis CI

The proper FTP wildcard init is now more properly done in Curl_pretransfer()
and the corresponding cleanup in Curl_close().

The previous place of init/cleanup code made the internal pointer to be NULL
when this feature was used with the multi_socket() API, as it was made within
the curl_multi_perform() function.
