After using the new vector stuff for real I found...
A bug in AST_VECTOR_INSERT_AT that could cause a seg fault.
The callbacks needed to be closer to ao2_callback in behavior
WRT to CMP_MATCH and CMP_STOP behavior and the ability to return
a vector of matched entries.
A pre-existing issue with APPEND and REPLACE was also fixed.
I also added a new macro to test.h that acts like ast_test_validate
but also accepts a return code variable and a cleanup label. As well
as printing the error, it sets the rc variable to AST_TEST_FAIL and
does a goto to the specified label on error. I had a local version
of this in test_vector so I just moved it.
