This removes all but the generic C RC4 implementation. At this point we
want to optimize for size/simplicity rather than speed.
See also upstream's 3e9e810f2e047effb1056211794d2d12ec2b04e7 which
removed the RC4_CHUNK code and standardized on RC4_INDEX. A
since-removed comment says that it was implemented for "pre-21164a Alpha
CPUs don't have byte load/store instructions" and helps with SPARC and
MIPS.
This also removes all the manual loop unrolling.

The generic RC4 implementation may read and write just past the end of the
buffer; when input and output are aligned, it always reads an RC4_CHUNK at a
time. It appropriately masks off and preserves the excess bytes off the end, so
this can only have practical effects if it crosses a page boundary. There's an
alignment check, so that can't happen; page boundaries are always aligned. But
it makes ASan unhappy and strictly speaking is a memory error.
Instead, fall through to the generic codepath which just reads it byte by byte.
This should fix the other bot failure.

RC4_CHUNK is always defined, RC4_INT is always uint32_t and the
"register" keyword is an anachronism.

This avoids unnecessary differences between LP64 and LLP64. Also
MSVC throws overflow warnings in the big-endian 64-bit codepath,
so use the preprocessor.

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.
