libbsdmalloc: Provide all allocator front ends and fork hooks.

Front ends:
- aligned_alloc
- calloc
- posix_memalign

Fork hooks:
- _malloc_prefork
- _malloc_postfork
- _malloc_postfork_child

Otherwise these will pull in the jemalloc definitions from libc,
which (a) defeats the purpose, and (b) won't work correctly with
fork and threads.

Thanks to kre@ and the thread on tech-userlevel for pointing me in
the right direction to making this actually work to override
jemalloc:
https://mail-index.netbsd.org/tech-userlevel/2023/06/30/msg013957.html

Note: libbsdmalloc doesn't set errno=ENOMEM on malloc failure, but
these front ends do (even aligned_alloc, which is from C11, which
doesn't define ENOMEM at all, but this pacifies our aligned_alloc
tests in t_posix_memalign.c).  Might want to fix that.

libbsdmalloc: Nix trailing whitespace.
No functional change intended.

libbsdmalloc: Bump shlib minor.
New symbols, new minor.

libbsdmalloc: New man page.

libbsdmalloc: Nix K&R definitions.  Bump WARNS to 3.

libbsdmalloc: Fix build with DEBUG.
Nix __P while here.

bsdmalloc.3: fix typos in function parameters
libbsdmalloc: Lift C11 divisibility restriction on aligned_alloc.
Restriction was lifted in C17.

libbsdmalloc: Make aligned_alloc(A, S) actually align when A > S.

t_posix_memalign: Simplify.
No functional change intended.

libbsdmalloc: Use a multiply-overflow that clang supports too.

bsdmalloc(3): fix malloc() signature

Make mstats() decl match prototype so this compiles with -DMSTATS.

libbsdmalloc: Fix sense of assertion in aligned_alloc.
