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.

This is the first structure to be implemented with the new BIGNUM ASN.1
routines. Object reuse in the legacy d2i/i2d functions is implemented by
releasing whatever was in *out before and setting it to the
newly-allocated object. As with the new d2i_SSL_SESSION, this is a
weaker form of object reuse, but should suffice for reasonable callers.
As ECDSA_SIG is more likely to be parsed alone than as part of another
structure (and using CBB is slightly tedious), add convenient functions
which take byte arrays. For consistency with SSL_SESSION, they are named
to/from_bytes. from_bytes, unlike the CBS variant, rejects trailing
data.
Note this changes some test expectations: BER signatures now push an
error code. That they didn't do this was probably a mistake.

Also implement it without reference to crypto/asn1 or fake ASN1_INTEGERs and
add a test. Some platform crypto APIs only give back the key size, and not the
encoded signature length. No sense in implementing it twice.

These functions are useful for implementing non-ASN.1-based protocols
like JSON Web Signature (JWS) and they are even already used within
Chromium.

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.

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.

Where possible, functions should return one for success and zero for
error. The use of additional negative values to indicate an error is,
itself, error prone.
This change fixes many EVP functions to remove the possibility of
negative return values. Existing code that is testing for <= 0 will
continue to function, although there is the possibility that some code
was differentiating between negative values (error) and zero (invalid
signature) for the verify functions and will now show the wrong error
message.

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.
