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.)

gcm_test.c includes a test case that does a 'malloc(0)'. This test case
currently fails if malloc(0) returns NULL.  According to the standard,
malloc's behavior with a size of 0is implementation specific and may
either be NULL or another pointer suitable to be passed to free().  This
change modifies gcm_test.c to handle a return value of NULL.  It has
been tested with a custom allocator on an experimental branch.

gcm_test.cc needs to access the internal GCM symbols. This is
unfortunate because it means that they have to be marked OPENSSL_EXPORT
just for this.

To compensate, modes.h is removed and its contents copied into
crypto/modes/internal.h.

This removes the confusion about whether |gcm128_context| copies the
key (it didn't) or whether the caller is responsible for keeping the
key alive for the lifetime of the |gcm128_context| (it was).

This is the only test amongst the tests for core crypto functionality
that depends on crypto/bio. This change removes that dependency. This
also factors out the duplicative hexdump logic into a shared function.

This isn't exhaustive. There are still failures in some tests which probably
ought to get C++'d first.

Including string.h in base.h causes any file that includes a BoringSSL
header to include string.h. Generally this wouldn't be a problem,
although string.h might slow down the compile if it wasn't otherwise
needed. However, it also causes problems for ipsec-tools in Android
because OpenSSL didn't have this behaviour.

This change removes string.h from base.h and, instead, adds it to each
.c file that requires it.

Chromium does not like static initializers, and the CPU logic uses one to
initialize CPU bits. However, the crypto library lacks an explicit
initialization function, which could complicate (no compile-time errors)
porting existing code which uses crypto/, but not ssl/.

Add an explicit CRYPTO_library_init function, but make it a no-op by default.
It only does anything (and is required) if building with
BORINGSSL_NO_STATIC_INITIALIZER.

Otherwise, in C, it becomes a K&R function declaration which doesn't actually
type-check the number of arguments.

(This change contains substantial changes from the original and
effectively starts a new history.)
