c8e5338a7c build: Rename LIBBSD_ABI to SOVERSION
This matches the semantics of the variable, and makes it independent of
the project, just as the package variables.

9fab225f26 Split errc family of functions from err ones
On most systems the err family of functions is already present, but are
missing the errc family of functions, which are also present on some
other systems. Splitting them into separate files will make it easer to
conditionally include one or the other.

10920c3084 build: Make name_from_id man pages conditional instead of id_from_name
The code is only making the name_from_id function conditional, and
assumes id_from_name are always to be included, so we need to match
the logic for the man page inclusion.

dec783dce5 build: Fix version script linker support detection
When the linker uses --no-undefined-version either specified by the user
or as the default behavior (such as with newer clang >= 16 releases),
a missing symbol definition will cause a linker error if that symbol is
listed in the version script.

e50896286c build: Do not require funopen() to be ported
This function cannot be easily and (more importantly) correctly ported
without cooperation from the libc stdio layer. We already document that
users should be prepared to have the function not available on some
platforms and that they should ideally switch their code to other
more portable and better interfaces.

Instead of making the build fail, and requiring porters to add
exceptions for something that most probably cannot be ported correctly
anyway, simply print a warning and let it build. This will not be a
regression because on those systems libbsd would have never been built
before.

e7cf8c5785 Switch md5 compatibility logic back to direct linking
When using the recent dlsym() based wrapper, we are not requiring any
symbol from libmd, as we resolve those dynamically at run-time. We were
ending up linking against libmd because in another part of the code we
require (depending on the architecture) the SHA512 functions for the
getentropy() local implementation. But that function might be provided
by the system libc on some systems, which means we end up not linking
against libmd at all.

To solve this we go back to the previous simpler solution of linking
directly, which had the main drawback of then making programs fail to
link when not specifying -lmd (on platforms that need it). And then
switch the .so link point from a symlink to a linker script, so that we
can inject the -lmd library as-needed. This is similar to what glibc is
doing.

25d35625eb build: Split libmd dependency due to MD5 functions from SHA requirements
To be able to rework the md5 deprecation logic, we need to detangle when
we depend on libmd due to requiring MD5 functions, which might be
otherwise provided by libc, or when we require SHA functions for the
internal getentropy() implementation.

31f034e386 Switch libmd wrapper to use dlsym()
Switch from the previous versioned symbol implementation which required

they would fail to find the symbols, to an implementation that loads
the symbols from the linked library providing the functions using
dlsym(), thus preserving backwards compatibility.
