The new functions are based on the code of make_filename from GnuPG.
They have been written by me ages ago with only minor modifications by
David Shaw. I re-license them from LGPL-3.0+ OR GPL-2.0+ to
LGPL-2.1-or-later.

The poll interface uses select(2) internally because that is more

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.
