d72e284271 Support arbitrary elliptic curve groups.
This change exposes the functions needed to support arbitrary elliptic
curve groups. The Java API[1] doesn't allow a provider to only provide
certain elliptic curve groups. So if BoringSSL is an ECC provider on
Android, we probably need to support arbitrary groups because someone
out there is going to be using it for Bitcoin I'm sure.

Perhaps in time we can remove this support, but not yet.

3bf1cca262 Don't report |ERR_R_MALLOC_FAILURE| on failure of |EC_KEY_new_by_curve_name|.
Change |EC_KEY_new_by_curve_name| to report |ERR_R_MALLOC_FAILURE|
itself, so that reporting of |EC_R_UNKNOWN_GROUP| is not confused by
the caller's addition of a spurious |ERR_R_MALLOC_FAILURE|.

126320c881 Add dummy EC_GROUP_set_point_conversion_form.
BoringSSL always uses uncompressed points. This function aborts if
another form is requested or does nothing if uncompressed points are
requested.

ad6b28e974 Add 64-bit, P-256 implementation.
This is taken from upstream, although it originally came from us. This
will only take effect on 64-bit systems (x86-64 and aarch64).

Before:

Did 1496 ECDH P-256 operations in 1038743us (1440.2 ops/sec)
Did 2783 ECDSA P-256 signing operations in 1081006us (2574.5 ops/sec)
Did 2400 ECDSA P-256 verify operations in 1059508us (2265.2 ops/sec)

After:

Did 4147 ECDH P-256 operations in 1061723us (3905.9 ops/sec)
Did 9372 ECDSA P-256 signing operations in 1040589us (9006.4 ops/sec)
Did 4114 ECDSA P-256 verify operations in 1063478us (3868.4 ops/sec)

c3ef76f327 Compatibility changes for wpa_supplicant and OpenSSH.
OpenSSH, especially, does some terrible things that mean that it needs
the EVP_CIPHER structure to be exposed ☹. Damian is open to a better API
to replace this, but only if OpenSSL agree too. Either way, it won't be
happening soon.

114ddebbf6 Unexport EC_GROUP_copy.
EC_GROUP_copy is an rather unfriendly function; it doesn't work if the groups
have different[*] underlying EC_METHODs, but this notion is not exposed through
the API. I found no callers of EC_GROUP_copy in external code.

This leaves the precompute_mult functions as the remaining mutable API exposed
through EC_GROUP.

[*] Though, of the two EC_METHODs right now, simple.c is entirely unused.

5b082e880d Various documentation fixes.
Add some missing headers and ensure each header has a short description. doc.go
gets confused at declarations that break before the first (, so avoid doing
that. Also skip a/an/deprecated: in markupFirstWord and process pipe words in
the table of contents.

eb7d2ed1fe Add visibility rules.
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.

4c921e1bbc Move public headers to include/openssl/
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.
