Make almost all the library selectable per target. Do not install manual

symbols in map file via pre-processor macros, and move the comments
describing the ABI selection to configure.ac.
For now the header files are included as is and filtered through

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.

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.

Switch libmd wrapper to use dlsym()
Switch from the previous versioned symbol implementation which required
users to also link against the message digest provider explicitly, or
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.

closefrom: Handle lowfd < 0 properly
More important if close_range() is going to be used, since casting
negative values to 'unsigned int' might hide the errors.

changes and refactoring.
In addition, refactor pstat implementation into closefrom_pstat(), so
that the code is easier to read, and requires no conditional
declarations.

Use libmd hashing function implementations instead of embedding our own
This splits the implementation responsibilities, and reduces embedded
code copies, which was one of the driving points with this project to
start with, so it's nice to give a good example.

Add recallocarray() and freezero() from OpenBSD
Add recallocarray(), introduced in OpenBSD 6.1, and freezero(),
introduced in OpenBSD 6.2. The former is imported as-is from OpenBSD,
while the latter is the non-malloc-internal branch of the same code (and
also the OpenSSH portable variant).
Both of these originated in OpenBSD, but have also been implemented by
IllumOS, cf. https://www.illumos.org/issues/8546
Documentation for these functions is in malloc(3) upstream, the relevant
parts of which were previously imported in reallocarray(3bsd). Update
reallocarray(3bsd) with the changes that were introduced since, and add
the relevant bits for recallocarray() and freezero(), plus aliases.

err: Add err(), warn(), errx() and warnx() familiy of functions
Some systems such as Windows or musl-libc based ones do not have these
BSD extensions. In addition libbsd itself is making use of the warnx()
functions, so we better provide these interfaces in case they are
missing.
