(gpa): Update to 0.9.10 (libpng, curl, gnutls, gettext, libiconv, zlib): Update. * NEWS: Mention changes. * Makefile.am (EXTRA_DIST): Update accordingly. * patches/gnutls-2.12.23: Move to gnutls-2.1.24 * patches/gpa-0.9.10/0001-Fix-crash-on-filename-conversion-error.patch: New.
This is in preperation for a 2.3.4 release, mainly to include
the newest libgcrypt. It is likely that not all gnutls patches
will apply. This will be fixed in a second commit.
