In r24137
Remove the MAHAF code and binaries, which doesn't work on anything more recent than Windows XP due to the usage of an unsigned driver. Remove the custom timer (PMT, TSC...) code to use the Windows recommended way aka, QueryPerformanceCounter (QPC) Remove the deprecated functions in wpthread relating to this. Some further cleanup will be needed, but this patch is already big enough.
This patch voluntarily excludes the Linux Fix for further investigation as we haven't ruled out a kernel bug yet;
