* configure.ac (gl_INIT): Add gnulib stuff.

(fseeko, ftello, ttyname, isascii): Replaced the AC_REPLACE_FUNCS
by a simple check.
(putc_unlocked): Removed check.  Not used.
(strsep, mkdtemp, asprintf): Replaced checks by gnulib checks.
(xsize): Added will probably come handy soon.
(CFLAGS): Use -Wformat-security instead of
-Wformat-nonliteral. Add --Wno-format-y2k.
* gl/, gl/m4/: New.

* gpg-agent.c: Include setenv.h.

* Makefile.am (AM_CPPFLAGS): Added.

* util.h: Add some includes for gnulib.
(ttyname, isascii): Define them inline.
* fseeko.c, ftello.c: Removed.
* strsep.c, mkdtemp.c: Removed.
* ttyname.c, isascii.c: Removed.

* mkdtemp.c: Removed.
* exec.c: Include mkdtemp.h

* keybox-file.c (ftello) [!HAVE_FSEEKO]: New replacement
function.  Copied from ../common/ftello.c.
* keybox-update.c (fseeko) [!HAVE_FSEEKO]: New replacement
function.  Copied from ../common/iobuf.c.

* scdaemon.c: Include mkdtemp.h.

* misc.c: Include setenv.h.

* symcryptrun.c: Include mkdtemp.h.
