This makes getting a pseudoterminal pair a little bit more portable.
Note that grantpt() and unlockpt() are currently no-ops, since we've
already granted the pseudoterminal slave to the calling user.
We also accept O_CLOEXEC to posix_openpt(), unlike some systems. :^)
Since BufferStream is about creating specific binary stream formats,
let's not have a flaky type like size_t in there. Instead, clients of
BufferStream can cast their size_t to the binary size they want to use.
Account for this in IPCCompiler by making String lengths always 32-bit.
Now that we're trying to be more portable, we can't only rely on using
i32/u32 and i64/u64 since different systems have different combinations
of int/long/long long and unsigned/unsigned long/unsigned long long.

sys$waitid() takes an explicit description of whether it's waiting for a single
process with the given PID, all of the children, a group, etc., and returns its
info as a siginfo_t.
It also doesn't automatically imply WEXITED, which clears up the confusion in
the kernel.
Notice that we are calculating release time according to the level when
the note is turned off rather than the sustain level. Naively using the
sustain level gives very long release times if you turn the note off
during attack, whereas this deterministically gives the same release
time.
1. Make decay sample-granular rather than buffer-granular
You only have ~43 buffers per second which can make a jagged signal.
2. Calculate decay in milliseconds
Decay is supposed to be a time value.
I say "phony" because it's not actually playing the same frequency
twice, it's just playing the same frequency at a higher volume. We can
properly implement this later but at the moment it'll get in the way of
our ADSR implementation.
Now you can change the defaults in AudioEngine and not be totally
confused.
1. The default for m_octave_knob was actually upside-down.
2. The default for m_decay_knob wasn't respecting AudioEngine.
3. The default for m_delay_knob wasn't respecting AudioEngine.
We add this feature together with the VMWareBackdoor class.
VMWareBackdoor class is responsible for enabling the vmmouse, and then
controlling it from the PS2 mouse IRQ handler.
