build: Abstract symbol versioning via new libbsd_symver_* macros
This makes it more obvious what they are doing. It will make it easier
to make these directives more portable, as they are really ELF specific.

Replace reintroduced legacy u_* type usage in strnvis() and strnunvis()
This fixes a regression caused by 2d7de18. These types are not available
on all systems.

Remove dead code in vis
The loop only executes while len > 0, and the trinary operator in the
function argument is checking against len >= 1 which will always be
true.

Fix vis family of functions to not leak
The code uses an internal helper function to avoid code repetition. But
to get there, the function takes a pointer to a pointer, so that the few
functions that require returning an allocated buffer can get hold of it
this way.
The problem is that the user might pass a NULL pointer and trigger an
internal allocation even if the functions are not expected to do so.
Add a new internal helper for non-allocations, that will assert that
condition, and make any other function that requires this behavior call
this one instead.

Fix strnvis() and strnunvis() NetBSD ABI break
The NetBSD implementations have different prototypes to the ones coming
from OpenBSD, which will break builds, and have caused segfaults at
run-time. We provide now both interfaces with different prototypes as
different version nodes allow selecting them at compile-time, defaulting
for now to the OpenBSD one to avoid build-time breakage, while emitting
a compile-time warning. Later on, in 0.10.0, we will be switching the
compile-time default to the NetBSD version.

Do not use legacy BSD u_* types
Some systems do not have these types available, and they are simply
convenience aliases. Instead use the expanded versions which are more
portable.

Conditionalize temporary compatibility inclusions
These inclusions were in place for backward compatibility purposes,
when the headers were split so that code using them would not break.
Make it possible for applications to disable them by defining
LIBBSD_CLEAN_INCLUDES so that buildability can be tested and fixed
before they get removed in a subsequent release.
