This change mirrors upstream's custom extension API because we have some
internal users that depend on it.

This change also switches the behaviour of the client. Previously the
client would send the SCSV rather than the extension, but now it'll only
do that for SSLv3 connections.

tls1_enc is now SSL_AEAD_CTX_{open,seal}. This starts tidying up a bit
of the record-layer logic. This removes rr->input, as encrypting and
decrypting records no longer refers to various globals. It also removes
wrec altogether. SSL3_RECORD is now only used to maintain state about
the current incoming record. Outgoing records go straight to the write
buffer.
This also removes the outgoing alignment memcpy and simply calls
SSL_AEAD_CTX_seal with the parameters as appropriate. From bssl speed
tests, this seems to be faster on non-ARM and a bit of a wash on ARM.
Later it may be worth recasting these open/seal functions to write into
a CBB (tweaked so it can be malloc-averse), but for now they take an
out/out_len/max_out trio like their EVP_AEAD counterparts.

Just about everything depends on SSL_CIPHER. Move it to the top as the first
section in ssl.h. Match the header order and the source file order and document
everything. Also make a couple of minor style guide tweaks.

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.

The variable switches the default type for add_library from STATIC to SHARED.
We can condition additional stuff on that for convenience. (tabtest still
doesn't build.)
BoringSSL as any kind of stable system shared library is still very much
unsupported, but this is probably handy for making sure we don't forget all
those pesky OPENSSL_EXPORTs.

This makes SSLv23_method go through DTLS_ANY_VERSION's version negotiation
logic. This allows us to get rid of duplicate ClientHello logic. For
compatibility, SSL_METHOD is now split into SSL_PROTOCOL_METHOD and a version.
The legacy version-locked methods set min_version and max_version based this
version field to emulate the original semantics.
As a bonus, we can now handle fragmented ClientHello versions now.
Because SSLv23_method is a silly name, deprecate that too and introduce
TLS_method.

Remove one more difference to worry about switching between TLS and SSLv3
method tables.
Although this does change the get_ssl_method hook for the version-specific
tables (before TLS and SSLv3 would be somewhat partitioned), it does not appear
to do anything. get_ssl_method is only ever called in SSL_set_session for
client session resumption. Either you're using the version-specific method
tables and don't know about other versions anyway or you're using SSLv23 and
don't partition TLS vs SSL3 anyway.

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.

SSL reason codes corresponding to alerts have special values. Teach
make_errors.go that values above 1000 are reserved (otherwise it will assign
new values in that namespace). Also fix all the existing reason codes which
