Add a shortcut for the "fake freeze" files to not expand include macros

Fix a core dump.

Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Make compilable from src/tools/m4 on non-NetBSD hosts.

Pull in various changes from OpenBSD, most from Marc Espie, including:
* Provide some GNUisms as extensions.
* Provide dynamically growable string space.
* Make define(defn(foo)) work correctly for builtins.
(The current version is supposed to be capable of satisfying autoconf.)

All still relevant NetBSD changes have been preserved in this version, and

WARNSify, fix .Nm usage, getopt returns -1 not EOF, deprecate register

Simplify some push-back code (e.g. for left and right quotes) so that
it uses pbstr() instead of doing the characters individually (in
reverse order) with putback().
Fix dodiv() so that divert(<out-of-range stream>) doesn't cause "divnum" to
return 0, but rather the stream number specified to divert(). Macros
like PUSHDIVERT/POPDIVERT rely on this. The new behaviour is compatible
with vendor m4 implementations.
