343983d9af [host] add timeout return value for repeated frame 
This is to allow a repeat frame without incuring an additional
memory copy when the frame is already in shared memory.

d4c41d2d94 [host] improve capture performance 
Contrary to the MS documentation, benchmarking shows a substantial
increase in performance when releasing the captured frame as soon
as possible. This change makes it possible to achieve 60FPS at 4K
resolutions.

80581a4aa2 [host] ask for unicode with mingw-w64 makefile 
Pass -DUNICODE as a CFLAG.  The visual studio project asks for
a unicode (wide-string) build, but the unix makefile did not.

This fixes the build on msys2.

758b7af754 [host] use a local copy of the header and then update it all in one go 
Writing to shared memory is much faster then reading as the shared
memory is not cached, this change ensures we are using a local copy
of the header performing the final update all in one go.

updated on every frame.

71c6e5d317 [host] NvFBC now takes full screen capture and crops off letterboxing

image using NvFBC.
