cleaning php-src root dir

Hi, the php-src/ dir is quite filled with outdated READMEs and TODOs, any objection to remove these files: README.PHP4-TO-PHP5-THIN-CHANGES README.QNX README.UPDATE_5_2 README.Zeus TODO TODO-5.1 TODO-PHP5 UPGRADING The TODOs seem to be quite outdated, the Upgrading guides for 5.0, 5.1 and 5.2 are part of the documentation meanwhile. 5.3 will get a new one. Related to that: ChangeLog in 5.3 is kind of awkward: It only lists changes in 2005, until HEAD became PHP 6. In HEAD it's a long file covering 2005-2008, anybody wants to clean that up :-) README.TESTING2 might need an update, run-tests2.php doesn't exist, but server-tests.php does, anybody maintining that? README.WIN32-BUILD-SYSTEM - does this require updating for the new build infrastructure? johannes
