* runtime/task_finder_vma.c (__stp_tf_get_vma_entry_addr): Deleted.
(struct __stp_tf_vma_entry): Replace module by user void* field.
(stap_add_vma_map_info): Take a void *user arg.
(stap_find_vma_map_info): Take a void **user arg.
* runtime/sym.c (_stp_mod_sec_lookup): Use stap_find_vma_map_info.

* runtime/task_finder_vma.c: Replace all mutex calls with appropriate
read or write (un)lock calls.

All callers of __stp_tf_get_vma_map_entry_internal lock and unlock
the mutex correctly themselves in all cases. This unlock would trigger
a double unlock.
* runtime/task_finder_vma.c (__stp_tf_get_vma_map_entry_internal):
Don't mutex_unlock(&__stp_tf_vma_mutex).

* tapsets.cxx (utrace_derived_probe_group::emit_module_decls):
Always emit vm callback probe for __stp_tf_vm_cb.
* runtime/task_finder.c (__stp_tf_vm_cb): Always expose, move _stp_dbug
statements under ifdef DEBUG_TASK_FINDER_VMA. Find and record
corresponding module when vm_path not NULL.
* runtime/task_finder_vma.c (struct __stp_tf_vma_entry): Add _stp_module.
(stap_add_vma_map_info): Add _stp_module argument and assign.
(__stp_tf_get_vma_entry_addr): New static function to get
the __stp_tf_vma_entry given an address.

* task_finder_vma.c (__stp_tf_vma_initialize): New function to
initialize the free list.
(__stp_tf_vma_put_free_entry): Puts a vma entry back on the free
list.
(__stp_tf_add_vma): Instead of allocating a vma entry, grab one
from the free list by calling __stp_tf_vma_put_free_entry().
(__stp_tf_remove_vma_entry): Instead of freeing a vma entry, call
__stp_tf_vma_put_free_entry() to put it on the free list instead.
* task_finder.c (stap_start_task_finder): Calls
__stp_tf_vma_initialize().
