Log message:
Fixes for SpiralSound/Midi.C

* test for failure of open() should be == -1, not == 0
	This causes Open() to behave as intended, only creating the
	m_MidiReader thread if the MIDI device is successfully opened.

* unconditionally initialize m_Mutex in Open()

* conditionally close m_MidiReader in Close(), if NULL do nothing

* make m_MidiFd and m_MidiWrFd the same file descriptor.  The MIDI
	device special file can only be opened once at a time.

Log message:
The problem is that SpiralSynth opens the MIDI device path before
calling SetDeviceName.

The call trace goes something like this:

Synth.C
main() ==> Synth *synth=new Synth; ==> Synth::Synth()
==> MidiDevice::Get()->SetDeviceName(SpiralInfo::MIDIFILE);

SpiralSound/Midi.h
MidiDevice::Get() ==> m_Singleton=new MidiDevice;
==> MidiDevice::MidiDevice() ==> MidiDevice::Open()
==> MidiDevice::SetDeviceName

patches/patch-ao works around this problem by closing the prematurely
opened private variable representing the MIDI device, and setting it to
NULL.  MidiDevice methods check for NULL and re-initialize the private
variable, this time opening the MIDI device path after SetDeviceName.
