  Fixed compile of tst_qscriptextensionplugin on some Windows configurations
  drop the SysV semaphores -specific code out from QWSSignalHandler
  minor refactoring of the QWSLock class
  simplify the code by using the EINTR_LOOP macro
  simplify the semaphores initialization
  minor refactoring of the QLock class
  add a warning on an incorrect usage of QLock
  make sure we really clear all locks
  fix build with QT_NO_QWS_SIGNALHANDLER
  use a printErr() function instead of std::cerr like in lupdate
  Re-apply licenseheader text in source files for qt4.8
  Fix build in C++0x mode
  skip the ipv6 Host checking for the moment, since it fails on Windows XP. will fix later
  Added some of my Qt 4.8 changes to the changelog
  remove duplicate message
  Update bearer startup code in network autotests
  symbian socket engine: share ip address conversion code
  fix "Host" header of ipv6 URLs in QNAM
  uic: Use QString::fromUtf8 for QUrl properties.
