This change fixes up several comments (many of which were spotted by
Kenny Root) and also changes doc.go to detect cases where comments don't
start with the correct word. (This is a common error.)
Since we have docs builders now, these errors will be found
automatically in the future.

Running make_errors.go every time a function is renamed is incredibly
tedious. Plus we keep getting them wrong.
Instead, sample __func__ (__FUNCTION__ in MSVC) in the OPENSSL_PUT_ERROR macro
and store it alongside file and line number. This doesn't change the format of
ERR_print_errors, however ERR_error_string_n now uses the placeholder
"OPENSSL_internal" rather than an actual function name since that only takes
the uint32_t packed error code as input.
This updates err scripts to not emit the function string table. The
OPENSSL_PUT_ERROR invocations, for now, still include the extra
parameter. That will be removed in a follow-up.

The only dependency the low-level crypto modules have on code in
crypto/obj is their use of OBJ_nid2sn, which is trivial to avoid.
This facilitates future simplification of crypto/obj, including
possibly the removal of functions like OBJ_nid2sn and the complex
build infrastructure that supports them.
This change also removes EVP_CIPHER_name and EVP_MD_name.

The EVP_CIPHER codepath should no longer be used with TLS. It still exists for
DTLS and SSLv3. The AEAD construction in TLS does not allow for
variable-overhead AEADs, so stateful AEADs do not include the length in the ad
parameter. Rather the AEADs internally append the unpadded length once it is
known. EVP_aead_rc4_md5_tls is modified to account for this.
Tests are added (and RC4-MD5's regenerated) for each of the new AEADs. The
cipher tests are all moved into crypto/cipher/test because there's now a lot of
them and they clutter the directory listing.
In ssl/, the stateful AEAD logic is also modified to account for stateful AEADs
with a fixed IV component, and for AEADs which use a random nonce (for the
explicit-IV CBC mode ciphers).
The new implementation fixes a bug/quirk in stateless CBC mode ciphers where
the fixed IV portion of the keyblock was generated regardless. This is at the
end, so it's only relevant for EAP-TLS which generates a MSK from the end of
the key block.

As useless as it might seem, the certificates in PKCS#12 files appear to
always be encrypted with 40-bit RC2. OpenSSL, NSS and Windows are all
the same on this point. Thus, in order to be able to import PKCS#12
files we need RC2 support.
RC2 has deliberately not been added to EVP_get_cipherbynid so that the
linker can drop the RC2 code unless the PKCS#12 functions are actually
called.

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.
