Replace GNUPG_GCC_A_ macros by GPGRT_ATTR_ macros.
* common/util.h: Provide replacement for GPGRT_ATTR_ macros when using
libgpg-error < 1.20.
* common/mischelp.h: Ditto.
* common/types.h: Ditto.
--

Given that libgpg-error is a dependency of all GnuPG related libraries
it is better to define such macros at only one place instead of having
similar macros at a lot of places.  For now we need repalcement
macros, though.

sc-copykeys doesn't work any more because it's based on old API.
pcsc-wrapper has gone because of nPth which is compatible to pthreads.

01a2a61bc4 scd: PC/SC reader selection by partial string match.
* scd/apdu.c (open_pcsc_reader_direct): Partial string match.

--

The card reader name by PC/SC service might include USB bus,
which varies (on some platform like GNU/Linux).  Thus, it's
better to match partial string.

Original patch was submitted by anstein.  I changed it to fallback to
the first reader if no match found.

Note that we need to change pcsc-wrapper.c in 2.0 backport.

gnulib has always been a cause of trouble in GnuPG because we used
only a very few functions and the complex include machinery of gnulib
is quite complex and the cause for many build problems for example on
OS X.  This is not gnulib's fault but due to our limited use of gnulib
and that we only rarely update the gnulib code to avoid regressions.

In part two we will address the functions

 mkdtemp
 setenv
 unsetenv
 strpbrk

which may bot be implemented on all platforms.  They are not required
on a libc based system.
