- Add gtar to BUILD_DEPENDS everywhere in moz.port.mk, since fx 18 will
start using gtar-only options. Ditto for unzip, used during install.
- special-case the deps for firefox/thunderbird/seamonkey, since those
are maintained on the long-term. Only those need to depend on the
latest and greatest nss/nspr.
- move the '--relax LDFLAGS for ppc' to moz.port.mk
- move the 'yasm BUILD_DEPENDS for i385/amd64' to moz.port.mk
- move more common CONFIGURE_ARGS to moz.port.mk (libevent,gio,bz2,gconf..)
- fix MODMOZ_WANTLIB wrt nss/nspr majors
- ensure we depend on sqlite3>=21, needed for fx/tb 18
- use --with-system-jpeg only in firefox36/sunbird/fennec/xulrunner,
fx/tb 18 will have to use its bundled libjpeg-turbo (#791305)
- bump REVISIONs for the WANTLIB/LIB_DEPENDS change.
