They do the same thing as OPENSSL_hexstr2buf() and OPENSSL_buf2hexstr(),
except they take a result buffer from the caller.
We take the opportunity to break out the documentation of the hex to /
from buffer conversion routines from the OPENSSL_malloc() file to its
own file. These routines aren't memory allocation routines per se.

The core provides a number of essential functions as "upcalls" to
providers. Some of those were just utility functions that wrap other
upcalls - which don't seem essential and bloat the interface. We should
remove them in order to simplify the interface.

After avoiding OPENSSL_memcmp for EC curve comparison, there are no remaining
uses in the source code. The function is only defined in an internal header
and thus should be safe to remove for 3.0.0.

When bufsize == 0, openssl_strerror_r should return 0 (if _GNU_SOURCE is defined),
to be consistent with non-_GNU_SOURCE variants, which exhibit the same behavior.
Fix a few cases, where the return value of openssl_strerror_r was ignored.

GNU strerror_r may return either a pointer to a string that the function
stores in buf, or a pointer to some (immutable) static string in which case
buf is unused.
In such a case we need to set buf manually.

return true for characters > 127. I.e. they are allowing extended ASCII
characters through which then cause problems. E.g. marking superscript '2' as
a number then causes the common (ch - '0') conversion to number to fail
miserably. Likewise letters with diacritical marks can also cause problems.
If a non-ASCII character set is being used (currently only EBCDIC), it is
adjusted for.
The implementation uses a single table with a bit for each of the defined
classes. These functions accept an int argument and fail for
values out of range or for characters outside of the ASCII set. They will
work for both signed and unsigned character inputs.

gcc's -Wextra pulls in -Wold-style-declaration, which triggers when a
declaration has a storage-class specifier as a non-initial qualifier.
The ISO C formal grammar requires the storage-class to be the first
component of the declaration, if present.
Seeint as the register storage-class specifier does not really have any effect
anymore with modern compilers, remove it entirely while we're here, instead of
fixing up the order.
Interestingly, the gcc devteam warnings do not pull in -Wextra, though
the clang ones do.

However, for the benefit of systems that don't get strings.h included
