dd9a0984 - xgettext: In language Vala, report out-of-range hexadecimal escapes.

xgettext: In language Vala, report out-of-range hexadecimal escapes. This avoids a later crash "Assertion `UNICODE_VALUE (c) >= 0 && UNICODE_VALUE (c) < 0x110000' failed." * gettext-tools/src/x-vala.c (phase7_getc): When the value of a hexadecimal escape sequence overflows, warn and use the last value before it overflowed. * gettext-tools/tests/xgettext-vala-7: New file. * gettext-tools/tests/Makefile.am (TESTS): Add it.
