Chris Adams 328d1d2fd6 Properly protect access to pixmap reader thread with mutex ... Previously, access to the reader thread wasn't guarded properly, causing a crash when the reader thread was deleted prior to QDeclarativePixmapData (which then attempted to dereference the thread pointer to cancel the request). This commit adds locking to ensure that access to the reader is protected properly. This commit also fixes an issue where if a QDeclarativePixmapData was deleted after its QDeclarativePixmapReply was removed from the jobs queue but prior to processing, a pointer to the data could be dereferenced as part of processing, but caching the required information in the reply.
