[PATCH] Refactor the bdb atomic initialization code into a generic implementation

[[[
Extract the atomic initialization code from libsvn_fs_base/bdb/env.c
and convert
it to a generic implementation that can be used to initialize other libraries
(*cough* Cyrus SASL *cough*). Make bdb use the new implementation.

* subversion/include/svn_atomic.h: New file.

* subversion/libsvn_subr/atomic.c: New file.

* subversion/libsvn_fs_base/bdb/env.c
  Include svn_atomic.h instead of apr_atomic.h.
  (svn__atomic_t,
   svn__atomic_read,
   svn__atomic_set,
   svn__atomic_cas): These are now in subversion/include/svn_atomic.h
  and have a single underscore. All calls were changed to reflect this.
  (BDB_CACHE_UNINITIALIZED,
   BDB_CACHE_START_INIT,
   BDB_CACHE_INIT_FAILED,
   BDB_CACHE_INITIALIZED): Deleted. Similar definitions are now in svn_atomic.h.
  (bdb_cache_state): This is no longer declared inside an #ifdef
APR_HAS_THREADS,
  and is initialized with SVN_INITIALIZED.
  (svn_fs_bdb__init_cb): New function. Contains bdb-specific initialization.
  (svn_fs_bdb__init): Call svn_atomic_init_once().
