[PATCH] Fix pool usage in FSFS locking code

[Sergey Raevskiy]

Hi!

I've noticed an improper pool usage in FSFS code.  The svn_lock_t * object is
created in RESULT_POOL, but its fiels are not gettting pstrdup'ed.

The patch with fix is attached.

Log message:
[[[
* subversion/libsvn_fs_fs/lock.c
  (lock_body): Fix pool usage. Call apr_pstrdup() when initializing svn_lock_t
   fields.
