fixed two init missing
Added SIP wrapping for Data::releaseBuffer
* Created new Release_Win7_Sync configuration 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)
Add default install path for libgsl (based on patch from S. Gara)
