Fixed and Changed NVidia Windows Driver Threaded optimization bug workaround of commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b

Commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b added a workaround
for the NVidia driver 260.99 for Window from 2010-12-11 issue.

[1] The workaround sets a process affinity while JOGL initialization
to mitigate NVidia driver's 'Threaded optimization := On' race conditions.
The process affinity is reset reset after initialization.

[2] The process affinity reset code had a bug, i.e. instead to restore the
original process's affinity mask, we restored the system's default affinity mask.

[3] Further more, there seem to be issues with changing a process affinity mask
regarding the process group.

This patch:
  - Solves issue [2] by using the original process affinity mask

  - Solves issue [3] by allowing a custom
    affinity mode via the property 'jogl.debug.windows.cpu_affinity_mode':

      - 0 - none (default, no affinity required for Windows NV driver >= 266.58 from 2011-01-24)
      - 1 - process affinity (was required w/ Windows NV driver 260.99 from 2010-12-11, see commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b)
      - 2 - thread affinity (experimental)

    Hence the workaround is disabled by default,
    since the crash as dicumented in commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b
    could not be reproduced with NV driver 266.58 from 2011-01-24.
