Use Coccinelle script to replace 'ret = E; return ret' with

Manual fixups:

* audio/audio.c: coding style of "read (...)" and "write (...)"
* block/qcow2-cluster.c: wrap line to make it shorter
* block/qcow2-refcount.c: change indentation of wrapped line
* target-tricore/op_helper.c: fix coding style of

* target-mips/dsp_helper.c: reverted changes because I don't

e58ff62d58 audio: pa: Set volume of recording stream instead of recording device
Since pulseaudio 1.0 it's possible to set the individual stream volume
rather than setting the device volume. With this, setting hardware mixer
of a emulated sound card doesn't mess up the volume configuration of the
host.

A side effect is that this limits compatible pulseaudio version to 1.0
which was released on 2011-09-27.

73bcb24d93 Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

7e274652e4 audio: Clean up inappropriate and unreachable use of hw_error()
audio_init() should not use hw_error(), because dumping CPU registers
is unhelpful there, and aborting is wrong, because it can be called
called from an audio device's realize() method.

The two uses of hw_error() come from commit 0d9acba:

* When qemu_new_timer() fails.  It couldn't fail back then, and it
  can't fail now.  Drop the unreachable error handling.

* When no_audio_driver can't be initialized.  It couldn't fail back
  then, and it can't fail now.  Replace the error handling by an
  assertion.

6dd35fd81e dsoundaudio: remove primary buffer
Enabling this option just creates a playback buffer with the specified settings,
and then ignores it. It's probably some outdated hack to set audio formats on
windows. (The first created stream dictates all other streams settings, at least
on some Windows versions). Setting DAC_FIXED_SETTINGS should have the same
effect as setting (the now removed) primary buffer.

b28fb27b5e audio: Don't free hw resources until after hw backend is stopped
When stopping an audio voice, call the audio backend's fini
method before calling audio_pcm_hw_free_resources_ rather than
afterwards. This allows backends which use helper threads (like
pulseaudio) to terminate those threads before the conv_buf or
mix_buf are freed and avoids race conditions where the helper
may access a NULL pointer or freed memory.

Change all the combinations to:

40a814b0b1 audio: Lower default wakeup rate to 100 times / second
This is more then plenty to keep audio card fifos filles / emptied.

This drops host cpu-load for audio playback inside a linux vm from
13% to 9%.

73204cffe5 ossaudio: check for oss support in oss_audio_init
Check whenever the device path (/dev/dsp by default) exists and qemu is
allowed to access it.  Return NULL if it isn't, so ossaudio will not
be used on systems wihtout oss support (increasinly common on modern
linux systems).
