Although, libgpg-error does not yet provide an API for multi-thread
support, it is useful to add the already available detection to the
config script. This allows the latest Libgcrypt to take advantage of
this in its regression tests. In particular for the regression tests
a gpgrt_thread functions would be useful and eventually added to
libgpg-error. The new gpg-error.m4 script should already be used by
other packages to be prepared for future updates.

This patch introduces the gpgrt_ functions which will be extended over
time to provide a library of commonly used code in GnuPG and
Libgcrypt. Having them in a library named libgpg-error is a misnomer
but this way we can achieve a smooth upgrade path.
In contrasts to other GnuPG libraries, the gpgrt_ functions return a
simple gpg_err_code_t and not gpg_error_t. The rationale for this is
that a source of error identifier does not make sense here; it is
better to use the source of error identifier of the caller. This can
easily be achieved in a component by wrapping these function in a
gpg_error macro/inline.
There is no cross-compiling support for Posix platforms; the
gen-posix-lock-obj tool must be run on the target system.
Note that the gen-w32-lock-obj tool is not needed at build time but
was used to figure out ABI definitions for Windows.
