70ab223490 Remove ASN1_R_MALLOC_FAILURE.
There was a TODO to remove it once asn1_mac.h was trimmed. This has now
happened. Remove it and reset error codes for crypto/asn1.

34248d4cb7 Get rid of err function codes.
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.

689be0f4b7 Reset all the error codes.
This saves about 6-7k of error data.

96396b3aaa Fix cross-module errors.
Some files in crypto/x509 were moved from crypto/asn1, so they emit errors from
another module. Fix make_errors.go to account for this: cross module errors
must use the foreign module as the first argument to OPENSSL_PUT_ERROR. Both
the function code and the error code should be declared in the foreign module.

Update make_errors.go to ignore cross-module error lines when deciding which
function tokens to emit.

29b186736c Precompute sorted array for error strings.
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.
