Norbert Federa ccc5d1b279 codec/rfx: fix multithreaded encoder 
Some component of the encoder chain (I suspect the rlgr encoder) expects
the output buffer to be zeroed. The multithreaded RemoteFX encoder uses
wStreams from the StreamPool which are reused and not zeroed out of
course. For now, in order to prevent data corruption we clear the stream.

Norbert Federa 938a0890a3 codec/rfx: removed unnecessary WaitForSingleObject 
The WaitForSingleObject call on TilePool's event is called with a zero time-out
interval and the event is a manual reset event ... thus no locking or waiting
is involved anyways and Queue_Dequeue may very well return NULL independently
of calling WaitForSingleObject which is already correctly handled.

Norbert Federa 1d384ce863 codec/rfx: removed unused queue TileQueue 
Declared, created, deleted but not used:

    git grep TileQueue
    libfreerdp/codec/rfx_types.h: wQueue* TileQueue;
    libfreerdp/codec/rfx.c:       context->priv->TileQueue = Queue_New(TRUE, -1, -1);
    libfreerdp/codec/rfx.c:       Queue_Free(context->priv->TileQueue);

Norbert Federa b9c8ac6527 codec/rfx: use function pointer for rlgr codec 
Option to switch the rlgr implementation during runtime - exactly
like we do it with the ycbcr, dwt and quantization functions.

Norbert Federa df7526f888 codec/rfx: Fixed bufferpool size used for RemoteFX 
y_r_buffer, cb_g_buffer, cr_b_buffer and dwt_buffer are all word arrays (16bit)
but obviously the bufferpool size was calculated based on the wrong assumption
that these are 32 bit values in commit 37a59efbe3

Norbert Federa b2108839b0 utils: fix broken stopwatch implementation 
Stopwatch (in the way it is used) must be able to measure the wall
clock time with high resolution but used clock() which is not
appropriate for this purpose:
On POSIX systems clock() returns the processor time used by the
program. On Windows clock() does measure the wall clock time but
has only a resolution of 1ms (if at all).
This also renders the freerdp profiler unusable.

This commit changes stopwatch to use the performance counters
on Windows and gettimeofday() for the rest.

Also added a warning about invalid profiling results to the
RemoteFX codec if rfxcontext->priv->UseThreads is enabled because
stopwatch is currently not used in a thread safe way.

Also see GitHub Issue #1325
