Files in lib/ are picked up and built using makefile directives in
src/Makefile.am. Remove the need to generate lib/Makefile.in and the
stub lib/Makefile.am.

Use reallocarray() when we have it (i.e. in OpenBSD system). When we
don't, use equivalent overflow detection for our allocate_array and
reallocate_array functions.
Remove lib/reallocarray.c from our LIBOBJS as we no longer need it.
Provide a fallback SIZE_MAX macro definition in flexint.h (not
preprocessor friendly, but enough for our reallocate_array use case).

The libcompat.la library was small and less friendly to bootstrapping
and cross compilation. Now, we will simply link individual object
files as needed, which is simpler.

Consistently make use of the ANSI C function definition style instead of
the K&R style.

This is taken from OpenSSH Portable, which in turn takes it from
OpenBSD.
reallocarray wraps the stdlib's realloc function. It takes two size
arguments and checks for overflow, like calloc, but doesn't zero the
memory. Therefore, it allows us to do overflow-safe array reallocations
and overflow-safe unzeroed array allocations, which the stdlib
allocation functions don't.
We have a bunch of specific array allocation macros, none of
which check for overflow. reallocarray should be able to replace them.

The *.[chly] sources are now in the src directory. This implies a
bunch of changes in Makefile.am and friends to account for the new
location. The .gitignore files are now more local to places where various object files and generated source files occur.
