Gitian uses patched Boost improperly #1579

Three problems:

• boost-win32.yml doesn't work at all because the patch isn't indented
• The #defines and #include should be moved to the relevant location in the Bitcoin code, not patched into the Boost dependency, or else native builds won't use the fix
• gitian-win32.yml still references 1.47 for qmake instead of 1.49

I recently took a look at Boost 1.50, which was released a few days ago ... it seems they took a different approach to fix this. See: http://www.boost.org/doc/libs/1_50_0/doc/html/interprocess/acknowledgements_notes.html#interprocess.acknowledgements_notes.release_notes.release_notes_boost_1_50_00

Seems with 1.50 we would need no monkey patches and I'm currently using it here.

Yeah, getting rid of the monkey patch is even better.

Closing this, boost 1.50 is now used
