lukem | m4 -g: { and } aren't supported in patsubst() or regexp()
When running in -g (GNU m4) emulation, patsubst() and regexp()
use the GNU m4 emacs-like regexes as implemented by gnulib,
which don't support {..} intervals.
When converting a GNU m4 regex to a POSIX ERE, escape raw { and }.
Autoconf relies on the GNU m4 regex behaviour.
See:
- https://www.gnu.org/software/autoconf/manual/autoconf-2.69/html_node/Redefined-M4-Macros.html
- https://www.gnu.org/software/gnulib/manual/html_node/emacs-regular-expression-syntax.html
This fixes the tools/compat/configure regen.

m4: fix typo in error message
To trigger the error message, compile m4 with -DREAL_FREEZE, then run
'./m4 -R /dev/null'.

christos | - don't eat the rest of the string when no match in patsubst
- include the pattern in the error printing of regex
- handle 3 argument and empty patterns the gnu way
- add support for freezing and thawing state (not working yet)

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).

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
formatting and style fixes have been applied in various places.
Thanks to Masao Uebayashi <uebayasi@soum.co.jp> for pointing this out.
