0197a58969 Windows compatibility fixes
VS2013 has trouble with relative include paths for apps/openssl, so move
certhash_win/apps_win.c back to apps/openssl.

gmtime_r on mingw64 fails with negative time_t, override

gmtime_s fails all of the time unit tests, override

SHUT_RD/WR are defined in newer mingw64 headers, check before overriding

5f4e95e7c1 updates for MSVC 2015's degenerate headers
Note that 'perror' moves from stdio.h to stdlib.h, and 'rename' moves
from stdio.h to io.h. Also, standard C includes move from the compiler
to the Windows SDK, which changes the base path for the include files.

5d8a1cf715 add initial CMake and Visual Studio build support
This moves the compatibility include files from include to
include/compat so we can use the awful MS C compiler
<../include/> trick to emulate the GNU #include_next extension.

This also removes a few old compat files we do not need anymore.

3096ab0e45 remove issetuigid wrappers, now that all getenv calls are gone.
From deraadt@ upstream:

Remove all getenv() calls, especially those wrapped by issetugid().
getenv()'s wrapped by issetugid() are safe, but issetugid() is ...
difficult to impliment on many operating systems.  By accident, a grand
experiment was run over the last year, where issetugid() returned 1 (the
safe value) on a few operating systems.  Noone noticed & complained that
certain environment variables were not working.......

dd646a3302 enable libtls by default
The API/ABI for the LibreSSL 2.1.x series is now fixed, so we can safely
enable libtls it by default. This is useful for new OpenNTPD and
OpenSMTPD releases as well.

e83c30c158 monkey patch more POSIX-like behavior out of winsock 2
Windows sockets functions look on the outside like they behave similarly
to POSIX functions, but there are many subtle and glaring differences,
including errors reported via WSAGetLastError, read, write, and close do
not work on sockets, setsockopt takes a (char *) rather than (void *),
etc.

This header implements wrappers that coerce more POSIX-like behavior
from these functions, making portable code easier to develop.

BENEFITS:
One does not necessarily need to sprinkle #ifdefs around code to handle
the Windows and non-Windows behavior when porting code.

CAVEATS:
There may be performance implications with the 'mother-may-I'
approach to determining if a descriptor is a socket or a file.

The errno mappings are not 100% what one might expect compared to POSIX
since there were not always good 1:1 equivalents from the WSA errors.

1bbde19a7c add minimal poll(2) implementation for Windows
This provides sufficient functionality to run openssl(1) from a Windows
console. This is based on the original select-based version from from
songdongsheng@live.cn. Changes:

 * use nfds_t directly for iterating the fds.
 * add WSAGetLastError -> errno mappings
 * handle POLLHUP and the OOB data cases for revents
 * handle sparse arrays of fds correctly
 * KNF style updates
 * teach poll how to handle file handles as well as sockets

This handles the socket/non-socket issue  by alternating a loop between
WaitForMultipleObjects for non-sockets and and select for sockets. One
would think this would be terrible for performance, but as of this
writing, poll consumes about 6% of the time doing a bulk transfer
between a Linux box and 'openssl.exe s_server'.

I tried to implement this all in terms of WaitForMultipleObjects with a
select 'poll' at the end to get extra specific socket status. However,
the cost of setting up an event handle for each socket, setting the
WSAEventSelect attributes, and cleaning them up reliably was pretty
high. Since the event handle associated with a socket is also global,
creating a new one cancels the previous one or can be disabled
externally.

In addition, the 'FD_WRITE' status of a socket event handle does not
behave in an expected fashion, being triggered by an edge on a write
event rather than being level triggered.

Another fun horror story is how stdin in windows might be a console, it
might be a pipe, it might be something else. If these all worked in the
same way, it would be great. But, since a console-stdin can also signal
on a mouse or window event, it means we can easily get stuck in a
blocking read (you can't make stdin non-blocking) if the non-character
events are not filtered out. So, poll does that too.

See here for various additional horror stories:

6dccbae663 update stdio.h for including stdarg.h
it seems that including stdarg.h is needed for defining va_list
environment is hpux 11.31(ia64) with gcc 4.7.1.

without stdarg.h, I got compilation error like this.
  "error: 'va_list' undeclared (first use in this function)"

I checked with gcc -E, then I noticed that __va_list is defined but va_list is not.
  "typedef __gnuc_va_list __va_list;"

with including stdarg.h, va_list is defined.
  "typedef __gnuc_va_list va_list;"
