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.

The BORINGSSL_YYYYMM #defines have served well to coordinate short-term skews
in BoringSSL's public API, but some consumers (notably wpa_supplicant in
Android) wish to build against multiple versions for an extended period of
time. Consumers should not do this unless there is no alternative, but to
accommodate this, start a BORINGSSL_API_VERSION counter. In future, instead of
BORINGSSL_YYYYMM #defines, we'll simply increment the number.
This is specifically called an "API version" rather than a plain "version" as
this number does not denote any particular point in development or stability.
It purely counts how many times we found it convenient to let the preprocessor
observe a public API change up to now.

I've used these defines to easy the update of BoringSSL in Android

the rest of Android and thus it's not possible to land changes the
atomically update several things at once.
For this I tended just to add this define in the Android copy of
BoringSSL, but we're starting to see that bleed into other situations
now so it's looking like this will be generally useful.
These defines may be added when useful but shouldn't build up: once the

The IUF functions were added for PEM and internally are very lenient to
whitespace and include other PEM-specific behaviors (notably they treat
hyphens as EOF). They also decode a ton of invalid input (see upstream's
RT #3757).
Upstream has a rewrite with tests that resolves the latter issue which
we should review and import. But this is still a very PEM-specific
interface. As this code has basically no callers outside the PEM code
(and any such callers likely don't want a PEM-specific API), it's
probably not worth the trouble to massage this and PEM into a strict IUF
base64 API with PEM whitespace and hyphen bits outside. Just deprecate
it all and leave it in a corner.

This change marks public symbols as dynamically exported. This means
that it becomes viable to build a shared library of libcrypto and libssl
with -fvisibility=hidden.
On Windows, one not only needs to mark functions for export in a
component, but also for import when using them from a different
component. Because of this we have to build with
|BORINGSSL_IMPLEMENTATION| defined when building the code. Other
components, when including our headers, won't have that defined and then
the |OPENSSL_EXPORT| tag becomes an import tag instead. See the #defines
in base.h
In the asm code, symbols are now hidden by default and those that need
to be exported are wrapped by a C function.
