of SOCKS headers for dynamic forwarding.

Create replacement header files inside openbsd-compat for common headers
that are missing on a given platform. Usually these are just empty,
but in some cases they'll include the equivalent file. This avoids
having to wrap those includes in '#ifdef HAVE_FOO_H' and reduces the
diff vs OpenBSD.
If we create any such headers, add the path to includes.
Initially just stdint.h, more to follow.

pointer arithmetic wherever possible.

Some AIX compilers unconditionally undefine va_copy but don't set it back
to an internal function, causing link errors. In some compat code we
already use VA_COPY instead so move the two existing instances into the
shared header and use for sshbuf-getput-basic.c too. Should fix building
with at lease some versions of AIX's compiler. bz#2589, ok djm@
apparently memcpy(x, NULL, 0) is undefined behaviour
according to C99 (cf. sections 7.21.1 and 7.1.4), so check skip memcpy calls

New buffer API; the first installment of the conversion/replacement
of OpenSSH's internals to make them usable as a standalone library.
This includes a set of wrappers to make it compatible with the
existing buffer API so replacement can occur incrementally.
