Log Message:
Update php-apc package to 3.1.6.

3.1.6		2010-11-30

- make slam_defense a little more optimistic, allow a thread/process to write
  to cache in a loop
- ensure realpaths hit the realpath_cache, in no-stat mode
- prevent memory starvation, nuke all caches when expunging just one doesn't
  work
- fix uploadprogress keylength issues (NUL is part of keylen, pecl bug #20016)

3.1.5		2010-11-02

- Reduce usage of CG(open_files) (mkoppanen at php dot net)
- Add support for php-trunk, new op code, new internals string format,
  etc. (Dmitry)
- apc_debug are not compiler-valid NOPs for non-debug builds

- Fixed relative paths resolution when ./foo/a.php or ../foo/a.php (or similar
  path) are used. 'foo/a.php' path behaviors remain unchanged
- Fixed a possible memory corruption, when partial path cannot be resolved by
  expand_filepath()
- Fixed notices in apc.php (Tomasz Krawczyk)

- Fixed Bug #17978: standardize user keys to include NULs in
  identifier_len. Z_STRLEN_P() doesn't, so add to it.
- Fixed bug #16966, apc produces tons of warnings "Unable to allocate memory
  for pool".

- Added --enable-apc-debug configuration argument to enable debugging (Kalle)
- Added support for internal debugging on Windows (Kalle)
