This commit was manufactured by cvs2svn to create branch 'APC_4_0'.
Initial commit for start of APC-4.0.0.  Multiple Cache support, LFU, apc.php rewrite, window stats.
# More to come, this is the initial commit of my private branch I've been maintaining.  INSTALL file is updated.
MFH: fix BC, do not use autoconf > 2.13 when developing extensions!
MFH: fix defines
- Missed one "#ifdef APC_HAVE_LOOKUP_HOOKS" line..
fix merge mistakes, apc_iterator_search_match arguments mismatch.
MFH: display mem_size and mem_avail as doubles so it can be displayed on 32-bit systems
MFH: Fix segfault with ? expressions (ZEND_JMP_SET), bug #16447
MFH: Correct mistake from previous fix, ZEND_JMP_SET is only for >2.3, fix for #16447
MFH: Fix #16540, apc_clear_cache() apparently returns false on success
MFH: fix APCIterator bugs when not properly initialized and  cache is empty
fix a huge number of wrong MIME types. UGH.
Add ability to dump CSV cache values from the browse page.  Patch by Lucas Nealan (lucas@php.net)
MFH: fix Bug #16083: handle zce->__callstatic member
MFH: Prevent race condition between PCRE and APC in module_init by moving the compilation of filters into the first request initialization.
fix previous commit, only call compile regex function if filters are set.
Add a "none" option for the expunge method.  This will not expunge entries on a cache-full scenario, and will issue a one-time error.
MFH: Fix bug #16747 APC fails to compile with __DEBUG_APC__ flag
* Fixed ZTS build
* Fixed builds without mmap support
Removed the old php4 dsp as in APC3.x
