remove gst_strtoll completely, since it didn't actually do anything more than what g_ascii_strtoull already does.

Original commit message from CVS:
* check/gst/gstvalue.c: (START_TEST), (gst_value_suite):
* gst/gstvalue.c: (gst_value_deserialize_int_helper):
remove gst_strtoll completely, since it didn't actually do
anything more than what g_ascii_strtoull already does.
check for range errors when deserializing
do a cast for the unsigned cases; but further fixing needs
a decision on what the interpretation of "(int)" and
deserialization should be for values that fall outside the
type's boundaries (ie, refuse, or interpret as casting)
