minor changes HWIOSIG / pco
Merge branch 'master' of github.com:esrf-bliss/Lima
Removed unnecessary additional HW status read in CtControl::getStatus
added new submodule for camera plugin xh
Again added submodule camera/xh, just forget something
Added real support for the new camera plugin Xh from Geoff Mant
Update for xh camera plugin python binding
Updated camera/xh
* Created new Release_Win7_Sync configurations (with S.Petitdemange & R.Homs):
  + for Processlib/LimaCore/PCO VS projects and solution
  + they define _WIN32_WINNT as 0x0600 (_WIN32_WINNT_LONGHORN)
    instead of 0x0502 (_WIN32_WINNT_WS03: WinXP SP2),
    which implies PTHREAD_WIN_XP_SYNC (XP API)
* Update of PCO project (R.Homs):
  + Implementation of HW RoIs & Live mode
  + Update SDK from v1.15 to v1.16
  + Improved buffer synchronisation management (for PyCcdLive)
* Add default install path for libgsl (based on patch from S.Gara)
* Improved SoftBufferCtrlObj::Sync management (with S. Petitdemange):
  + Fixed additional cond. mutex lock in wait: already locked by caller
  + Return TIMEOUT in wait only if buffer is not AVAILABLE
  + Allow multiple users of same buffer, needed by async. PyCcdLive
* Added support for EDF files larger than 2 GBytes (S. Petitdemange)
* Included saving_index_format Tango attr. in limaacq & limacore (R.Homs)
* Call Data.releaseBuffer() once it is no longer needed
  so it can potentially be used by the hardware layer
  through the SoftBufferCtrlObj::Sync mechanism
