1ae23ad935 - MONITORX/MWAITX: It is possible that MWAITX wakeup from timed mwait but APIC timer was still not reset.
A corruption would happen if MWAIT is called again to setup the timer while it still running from previous time.
  Also spurious wakeup could possibly happen as timer will send wakeup when it stops counting.

address most of the memory leaks (#149)
the param tree, siminterface log and SIM were not released handle all
but SIM for now
should reduce the memory leaks list dramatically

32c7c3815a Display lib options 'cmdmode' and 'gui_debug' are now ignored by the wxWidgets port.
Using a bochsrc config designed for another gui no longer causes a BX_PANIC for unknown option.

Close cdrom image file on eject (#145)
The WIN32 configuration for the cdrom was not closing the image file on
eject. This left the handle open while Bochs was running, not allowing
the image file to be modified.

591e2aa79f bugfix: when CET was not compiled in the emulation behavior of non-CET CPU was altered
CET 'change' some x86 behavior
For example EPTP[7] become not-reserved and write to it not fail anymore
VMX doesn't check error code for CP exception if CET is enabled
These behaviors these changed even when CET was not compiled in

reset status bar items at reset (#142)
When the user presses the "Reset" button on the gui ribbon, we need to
clear the active status of all statusbar items or they remain set after
the reset occurs.

6aa399e9eb Added x64 configuration for the VS2019 plugins workspace (fixes issue #8).

was necessary (adding OutDir/IntDir stuff).
