The tracetool script is written in shell and has hit several portability
problems due to shell quirks or external tools across host platforms.
Additionally the amount of string processing and lack of real data
structures makes it tough to implement code generator backends for
tracers that are more complex.

This patch replaces the shell version of tracetool with a Python
version.  The new tracetool design is:

  scripts/tracetool.py - top-level script
  scripts/tracetool/backend/ - tracer backends live here (simple, ust)
  scripts/tracetool/format/  - output formats live here (.c, .h)

There is common code for trace-events definition parsing so that
backends can focus on generating code rather than parsing input.

Support for all existing backends (nop, stderr, simple, ust,
and dtrace) is added back in follow-up patches.

If the audio backend is capable of volume control, don't apply
software volume (mixeng_volume ()), but instead, rely on backend

control.

Basically, the main wait loop calls qemu_run_all_timers() unconditionally. The
first thing this routine used to do is to see if a timer had been serviced,
and then reset the loop timeout to the next deadline.

However, the new deadlines had not been calculated at that point, as
qemu_run_timers() had not been called yet for each of the clocks. So
qemu_rearm_alarm_timer() would end up with a negative or zero deadline, and
default to setting a 250us timeout for the loop.

As qemu_run_timers() is called for each clock, the real deadlines would be put
in place, but because a loop timeout was already set, the loop timeout would
not be changed.

Once that 250us timeout fired, the real deadline would be used for the
subsequent timeout.

For idle VMs, this effectively doubles the number of times through the loop,
doubling the number of select() system calls, timer calls, etc. putting added
scheduling pressure on the kernel. And under cgroups, this really causes a big
problem because the cgroup code does not scale well.

By simply running the timers before trying to rearm the timer, we always rearm
with a non-zero deadline, effectively halving the number of system calls.

Once a chr frontend is able to receive input again, we need to inform
the io-thread about this fact. Otherwise, main_loop_wait may continue to
select without the related backend file descriptor in its set. This can
cause high input latencies if only low-rate events arrive otherwise.

As long as we have no link and we aren't in internal loopback mode, no

pcnet_stop already clears any reason (BABL, CERR, MISS, MERR) why ERR

tb.time is a time value, but not necessarily of the same size as time_t:
while time_t is 64 bit for w64, tb.time still is 32 bit only.

Replace all type casts to 'long' or 'unsigned long' by 'intptr_t' or 'uintptr_t'.

For type casts which are only used to extract the lower bits of an address
or to modify those bits, signedness does not matter. There I always use 'uintptr_t'.

For w64, some entries need 'uintptr_t' instead of 'unsigned long'.

The default definition of setjmp which is implemented in MinGW-w64
cannot be used with programs like QEMU which call longjmp from
code without structured exception handling (SEH).

This code therefore disables stack unwinding.

We could also implement SEH for QEMU's generated JIT code, but
that is much more difficult. Stack unwinding would also cost
execution time.
