There's a __pragma expression which allows this. Android builds us Windows with
MinGW for some reason, so we actually do have to tolerate non-MSVC-compatible
Windows compilers. (Clang for Windows is much more sensible than MinGW and
intentionally mimicks MSVC.)
MinGW doesn't understand MSVC's pragmas and warns a lot. #pragma warning is
safe to suppress, so wrap those to shush them. This also lets us do away with a
few ifdefs.

Many of the compatibility issues are described at
https://msdn.microsoft.com/en-us/library/mt612856.aspx. The macros
that suppressed warnings on a per-function basis no longer work in
Update 1, so replace them with #pragmas. Update 1 warns when |size_t|
arguments to |printf| are casted, so stop doing that casting.
Unfortunately, this requires an ugly hack to continue working in
MSVC 2013 as MSVC 2013 doesn't support "%zu". Finally, Update 1 has new
warnings, some of which need to be suppressed.

Updated by davidben to give up on suppressing warnings in crypto/x509 and
crypto/x509v3 as those directories aren't changed much from upstream. In each
of these cases, upstream opted just blindly initialize the variable, so do the
same. Also switch C4265 to level 4, per Microsoft's recommendation and work
around a bug in limits.h that happens to get fixed by Google include order
style.
(limits.h is sensitive to whether corecrt.h, pulled in by stddef.h and some
other headers, is included before it. The reason it affected just one file is
we often put the file's header first, which means base.h is pulling in
stddef.h. Relying on this is ugly, but it's no worse than what everything else
is doing and this doesn't seem worth making something as tame as limits.h so
messy to use.)

This change makes the AEAD and EVP code paths use the same code for
AES-GCM. When AVX instructions are enabled in the assembly this will
allow them to use the stitched AES-GCM implementation.
Note that the stitched implementations are no-ops for small inputs
(smaller than 288 bytes for encryption; smaller than 96 bytes for
decryption). This means that only a handful of test cases with longish
inputs actually test the stitched code.

arm_arch.h is included from ARM asm files, but lives in crypto/, not
openssl/include/. Since the asm files are often built from a different
location than their position in the source tree, relative include paths
are unlikely to work so, rather than having crypto/ be a de-facto,
second global include path, this change moves arm_arch.h to
include/openssl/.
It also removes entries from many include paths because they should be
needed as relative includes are always based on the locations of the
source file.

`cmake -GNinja .. -DCMAKE_BUILD_TYPE=Release` fails without this
patch, when building using MSVC 2013.
MSVC will detect (in release builds only, it seems) that functions that
call abort will never return, and then warn that any code after a call
to one of them is unreachable. Since we treat warnings as errors when
building, this breaks the build. While this is usually desirable, it
isn't desirable in this case.

even in 32-bit mode. AES and GHASH should Just Work in this case: the
-armx.pl files can be built for either 32- or 64-bit mode based on the
flavour argument given to the Perl script.
SHA-1 and SHA-256 don't work like this however because they've never
