Beyond generally eliminating unnecessary includes, eliminate as many
includes of headers that declare/define particularly error-prone
functionality like strlen, malloc, and free. crypto/err/internal.h was
added to remove the dependency on openssl/thread.h from the public
openssl/err.h header. The include of <stdlib.h> in openssl/mem.h was
retained since it defines OPENSSL_malloc and friends as macros around
the stdlib.h functions. The public x509.h, x509v3.h, and ssl.h headers
were not changed in order to minimize breakage of source compatibility
with external code.

A previous change in BoringSSL renamed ERR_print_errors_fp to
BIO_print_errors_fp as part of refactoring the code to improve the
layering of modules within BoringSSL. Rename it back for better
compatibility with code that was using the function under the original
name. Move its definition back to crypto/err using an implementation
that avoids depending on crypto/bio.

Since ERR will soon have thread-local storage, we don't need to worry
about high-performance implementations and thus don't need to be able to
switch two different implementations at run-time.

Previously, error strings were kept in arrays for each subdirectory and
err.c would iterate over them all and insert them at init time to a hash
table.
This means that, even if you have a shared library and lots of processes
using that, each process has ~30KB of private memory from building that
hash table.
This this change, all the error strings are built into a sorted list and
are thus static data. This means that processes can share the error
information and it actually saves binary space because of all the
pointer overhead in the old scheme. Also it saves the time taken
building the hash table at startup.
This removes support for externally-supplied error string data.

As feared, 2bca0988 did cause some leak checkers to get upset about the
state_hash pointer getting cleared.
This change makes err_shutdown free all the error queues to try and
avoid this. Hopefully this doesn't upset TSAN in turn.

The extra free in ex_data_impl.c is fixing a mistake: when calling
|CRYPTO_cleanup_all_ex_data| the |EX_CLASS_ITEM| itself wouldn't be
freed.
The change in err_impl.c is to free the thread-id hash also. This allows
programs to free absolutely all memory allocated by BoringSSL, which
allows fuzz testing to find any memory leaks.

Some parts of Android can't be updated yet so this change adds

Android-specific code. (That Android-specific code will live in the
Android repo, not the BoringSSL repo.)
Trying to use these functions outside of Android will result in a link

I misunderstood the OpenSSL semantics here. When receiving an error data
pointer via ERR_get_error_line_data and friends, although the error is
cleared, OpenSSL retains ownership of the data pointer. It's kept in the
cleared error until another error overrides it, or the whole error queue
is cleared.
It's pretty odd to have live pointers in empty errors so this change
allows an error queue to retain one data pointer. Thus the pointer
returned from ERR_get_error_line_data is valid until the next call to
ERR_get_error_line_data, or until the queue is freed.
From reviewing uses of the API, this is sufficient for all of them.

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.

Previously, public headers lived next to the respective code and there
were symlinks from include/openssl to them.
This doesn't work on Windows.
This change moves the headers to live in include/openssl. In cases where
some symlinks pointed to the same header, I've added a file that just
includes the intended target. These cases are all for backwards-compat.
