FreeRDP uses clipboard->data to cache the result of the Windows->X11
clipboard format conversion, and xf_cliprdr_process_selection_request()
immediately provides this result to local applications if they request
the same clipboard format again. This saves us a possibly costly
conversion in case where the user pastes data repeatedly.
However, this caching mechanism did not support raw clipboard transfers
where the unmodified data is passed between two FreeRDP clients. We use
the same XClipboard protocol for this, so the clipboard->data is in play.
We clear the cached value when we receive new data from the server, so
initially raw transfers are fine. But if some local application (e.g.,
a clipboard manager) asks for some data format before the data is pasted
into the second FreeRDP session then clipboard->data will contain the
*converted* data. And this converted cached data will be provided to
the second FreeRDP session as a part of the raw data transfer. Instead
we should have provided the original data.
In order to achieve this we are now caching the original data in the
same way as the converted one, and the original data is now correctly
provided when the second FreeRDP session asks for a raw data transfer.
Allow password to be stored in .RDP file and parsed and settings
updated, this will allow for dynamic .RDP files to be created with
complete login credentials, using this method the username, server and
password will no longer be visible within process lists.
Also fixed issue of username and domain being read from .RDP files and
set to null by command line processor.
Currently supported source pixel formats are:
- PIXEL_FORMAT_BGRA32
- PIXEL_FORMAT_BGRX32
Support for PIXEL_FORMAT_RGB[XA]32 can simply be added if
required (see the comment in prim_YUV_opt.c).
On my old 3.1 GHz Core i5-2400 the new SSSE3 function can convert
over 900 1080p BGRX frames per second.
The current non-optimized C version (which supports all pixel formats)
can't do more than 40 yuv conversions per second on this cpu.

Also fixed an error in TestPrimitivesYUV which generated resolutions
