Some ARM environments don't support |getauxval| or signals and need to
configure the capabilities of the chip at compile time. This change adds
defines that allow them to do so.

This fixes an issue with Clang, which doesn't like static functions that

Td4 is an array of u8. A u8 << int promotes the u8 to an int first then shifts.
If the mathematical result of a shift (as modelled by lhs * 2^{rhs}) is not
representable in an integer, behaviour is undefined. In other words, you can't
shift into the sign bit of a signed integer. Fix this by casting to u32
whenever we're shifting left by 24.
(For consistency, cast other shifts, too.)

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.
In order to support Chromium, a couple of libssl functions were moved to
ssl.h from ssl_locl.h: ssl_get_new_session and ssl_update_cache.

Windows complains when the declaration of a function doesn't match the
definition. In this case, the |bits| argument (not a pointer, just an
unsigned) was marked as const in the definition only.
Normally const isn't used for non-pointer arguments so I've removed it
in this case to make Windows compile.
