Warning: Using --disable-threads creates a different ABI which we
can't encode in the the cpu-vendor-os triplet. The run time checks
should detect this and abort the process.

This is only doe for the old API. The estream API needs to be added.

* src/posix-lock.c (gpgrt_lock_init): Detect unitialized lock var.
* src/w32-lock.c (gpgrt_lock_init): Ditto.
--
gpgrt_lock_init may be used for dynamically allocated locks. For
example
gpgrt_lock_t *lock = xcalloc (1, sizeof *lock);
gpgrt_lock_init (lock);
gpgrt_lock_lock (lock);
foo ();
gpgrt_lock_unlock (lock);
gpgrt_lock_destroy (lock);
free (lock);
This patch actually allows for this.

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.
