cleanup, tags: Create tags for the cleanup primitives

Oleg reported that it is hard to find the definition of things like:
__free(argv) without having to do 'git grep "DEFINE_FREE(argv,"'.

Add tag generation for the various macros in cleanup.h.

Notably 'DEFINE_FREE(argv, ...)' will now generate a 'cleanup_argv'
tag, while all the others, eg. 'DEFINE_GUARD(mutex, ...)' will
generate 'class_mutex' like tags.
