* autoload.cc (timeBeginPeriod): Autoload.

Browse Source 
* dcrt0.cc (dll_crt0_1): Use timeBeginPeriod to set default resolution to 1 ms.
* pinfo.cc (pinfo::thisproc): Set ppid for redirected _pinfo blocks too.
(pinfo::init): Avoid using VirtualQuery.  Just rely on the assumption that
procinfo will be populated.
* pinfo.h (_pinfo::ppid): Move into redirected block.
