Lluís VilanovaandStefan Hajnoczi 864a2178d4 trace: [tcg] Do not generate TCG code to trace dynamically-disabled events
If an event is dynamically disabled, the TCG code that calls the
execution-time tracer is not generated.

Removes the overheads of execution-time tracers for dynamically disabled
events. As a bonus, also avoids checking the event state when the
execution-time tracer is called from TCG-generated code (since otherwise
TCG would simply not call it).

Marc-André LureauandMarkus Armbruster 086ee7a620 scripts: use build_ prefix for string not piped through cgen()
The gen_ prefix is awkward.  Generated C should go through cgen()
exactly once (see commit 1f9a7a1).  The common way to get this wrong is
passing a foo=gen_foo() keyword argument to mcgen().  I'd like us to
adopt a naming convention where gen_ means "something that's been piped
through cgen(), and thus must not be passed to cgen() or mcgen()".
Requires renaming gen_params(), gen_marshal_proto() and
gen_event_send_proto().

Paolo Bonzini e8c2091d4c checkpatch: should not use signal except for SIG_DFL or SIG_IGN
Using signal to establish a signal handler is not portable; on
SysV systems, the signal handler would be reset to SIG_DFL after
delivery, while BSD preserves the signal handler.  Daniel Berrange
reported that (to complicate matters further) the signal system call
has SysV behavior, but glibc signal() actually calls the sigaction
system call to provide BSD behavior.

However, using signal() to set a signal's disposition to SIG_DFL
or SIG_IGN is portable and is a relatively common occurrence in
QEMU source code, so allow that.

Eduardo Habkost 23ea4f3032 scripts: Test script to look for -device crashes
Test code to check if we can crash QEMU using -device. It will
test all accel/machine/device combinations by default, which may
take a few hours (it's more than 90k test cases). There's a "-r"
option that makes it test a random sample of combinations.

The scripts contains a whitelist for: 1) known error messages
that make QEMU exit cleanly; 2) known QEMU crashes.

This is the behavior when the script finds a failure:

* Known clean (exitcode=1) errors generate DEBUG messages
  (hidden by default)
* Unknown clean (exitcode=1) errors will generate INFO messages
  (visible by default)
* Known crashes generate error messages, but are not fatal
  (unless --strict mode is used)
* Unknown crashes generate fatal error messages

Having an updated whitelist of known clean errors is useful to make the
script less verbose and run faster when in --quick mode, but the
whitelist doesn't need to be always up to date.
