Use temporary variable to prevent multiple evaluations of elem argument.
This resolves a memory leak in res_pjproject startup.

Added an pre-defined integer vector declaration. This makes integer vectors
easier to declare and pass around. Also, added the ability to default a vector
up to a given size with a default value. Lastly, added functionality that
returns the "nth" index of a matching value.

Also, updated a unit test to test these changes.

ASTERISK_REGISTER_FILE no longer has any purpose so this commit removes
all traces of it.

Previously exported symbols removed:
* __ast_register_file
* __ast_unregister_file
* ast_complete_source_filename

This also removes the mtx_prof static variable that was declared when
MTX_PROFILE was enabled.  This variable was only used in lock.c so it
is now initialized in that file only.

Based on feedback from Corey Farrell and Y Ateya, a few new
macros have been added...

AST_VECTOR_REMOVE which takes a parameter to indicate if
order should be preserved.

AST_VECTOR_ADD_SORTED which adds an element to
a sorted vector.

AST_VECTOR_RESET which cleans all elements from the vector
leaving the storage intact.

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.

Renamed AST_VECTOR_INSERT to AST_VECTOR_REPLACE because it really
does replace not insert.  The few users of AST_VECTOR_INSERT were
refactored.  Because these are macros, there should be no ABI
compatibility issues.

Added AST_VECTOR_INSERT_AT that actually inserts an element into the
vector at a specific index pushing existing elements to the right.

Added AST_VECTOR_GET_CMP that can retrieve from the vector based
on a user-provided compare function.

Added AST_VECTOR_CALLBACK function that will execute a function
for each element in the vector.  Similar to ao2_callback and
ao2_callback_data functions although the vector callback can take
a variable number of arguments.  This should allow easy migration
to a vector where a container might be too heavy.

Added read/write locked vector and lock manipulation macros.

Added unit tests.
