use %u instead of %d, merge from pecl/phar

- ws/cs, macros, code that only affects other branches
- some unsynced changes need valgrind testing before they can go into this branch, see PECL/HEAD

fix folding

- Utilize new UNIX_PATHS flag in SPL
- Fix tests

@Jani: hold back on the bunny-killing, HEAD will be in sync later today

Improved webPhar speed (frontcontroller11.phar.phpt is disabled, should be removed)

Improved support for opcode caches. Now some open() syscalls might be eliminated by caches.

Fixed efree(NULL)

- We forgot to check that the phar exists before trying to extract files from it :)

fix several issues:
1) segfault in phar_buildfromdirectoryiterator8.phpt
2) tests failing because SKIPDOTS is default on 64 bit, not on 32
3) Marcus, you really need to add SKIPDOTS as a

2) tests failing because SKIPDOTS is default on 64 bit, not on 32
3) Marcus, you really need to add SKIPDOTS as a class constant, so we don't have to use 0x00001000

true fix for potential segfault in phar_build

- Revert the two blocks of code that implement the phar_build optimization, causes segfaults under *nix
- Leave the new structure in place to make re-implementation trivial

- ws, typo fix

82x(./profile2) speedup for buildFrom*()

- Fix ZTS build (not required on HEAD, patch by Uwe Pries)

making progress - up to 42/phar vs. 48/disk with these optimizations

fix windows build and more performance jumps (these are minor)
implement real copy-on-write
use virtual_dirs for wrapper stat

another optimization - move inode hash to initial manifest parsing, improves runtime perf of stat slightly

minor optimization

HUGE speed improvement, from 19 req/sec to 27 req/sec for phpMyAdmin - now speed with apc+phar.cache_list = on-disk speedcvs diff -u |less This is by generating a list of virtual directories and usi

[DOC] implement full signature support for tar-based archives. By default, data archives do
not have a signature, but can have one set via setSignatureAlgorithm()

full refactor of signatures complete - now to implement them for tar as a starting point

fix PHP Bug #45218: PHAR archive built from directory limited by max open file handles

- Need to use a proper inheritance check
