Merge branch 'PHP-5.4' of git.php.net:php-src into PHP-5.4

* 'PHP-5.4' of git.php.net:php-src: (101 commits)
  exif NEWS
  add tests for bug #62523
  Merged PR #293 (Exif crash on unknown encoding was fixed) By: 	Draal Conflicts: 	configure.in 	main/php_version.h
  Just SKIP that test on travis
  fix memory leak on error (from Coverity scan)
  Fix coverity issue with -1 returned by findOffset not being handled by getPreferredTag
  5.4.21 release date
  When src->src is null this doesn't get initialized but it is still used, so the passed in *ze will point to unitialized memory. Hopefully src->src is never null, but just in case this initialization doesn't hurt.
  Fix typo
  Clean up this weird safe_emalloc() call
  Minor Coverity tweaks
  - Moved NULL check before dereferencing
  - Fixed possible NULL ptr dereference
  - Fixed possible uninitialized scalar variable usage (spotted by Coverity)
  Remove senseless check here
  - Fix extern declaration according to definition
  - Fix possible memory leak
  - Moved allocation to if block to make Coverity happy
  - Fixed possible memory leak
  Fix unitialized opened_path here - found by Coverity
