core: Replace all calls to *sprintf by gpgrt_*sprintf.

* configure.ac (vasprintf): Remove check.
* src/vasprintf.c: Remove file.
* src/util.h (vasprintf, asprintf): Remove prototypes.  Replace all
calls to vasprintf and asprintf by gpgrt_vasprintf or gpgrt_asprintf.
Also take care to use gpgrt_free on the returned value.
* src/w32-util.c (_gpgme_get_gpgconf_path): Replace a gpgrt_asprintf
by _gpgme_strconcat.
(snprintf): New macro to use gpgrt_snprintf instead of the system's
standard snprintf.
