07137c0267 ioplug - Fix the refinement of period_* after periods 
When changing only PERIODS after BUFFER_*, ioplug doesn't update
the corresponding PERIOD_* parameters properly.  This should fix
ALSA bug#2601.

2e7cc001a9 Re-add assert.h to asoundlib.h 
Looks like many apps rely on implicit inclusion of assert.h in asoundlib.h.
Take it back again to make them happy.

54a2cf5ecf Remove sequencer instrument layer 
Remove obsoleted sequencer instrument layer from alsa-lib.
The old symbols are compiled in as default as dummy functions
(unless --disable-old-symbols is given to configure) so that
the old binaries can still work more or less.

68e5771a6f Remove assert from header files 
Putting assert in the public macros isn't good idea at all.
Let's get rid of them.

Also, clean up snd*_alloca() functions to use a helper macro
instead of copy and paste.

9eb272c753 Fix gcc compile warnings 
Fix gcc compile warnings with nasty const cast.  Let's use simply macros
instead of inline functions.  It's just an array access after all...

f38e5feca3 Export dB conversion helper functions 
Export helper functions to convert dB level and range.

snd_tlv_*dB*() are to convert dB level or range directly from TLV data.
snd_ctl_*dB*() are to get dB level or range from a control element.

631f7cde82 Change assert condition in error message handler 
Activating assert() in the default error message handler isn't always
good for producitve systems.  Make this optional and enable only when
a special configure option is given (i.e. for explicit debugging).

d6093c58f3 snd_pcm_dmix_close: raise semaphore if unable to discard 
This patch causes snd_pcm_dmix_close() to up a semaphore after downing it
if it is unable to discard it.  It prevents some deadlock that I am
getting when a couple of applications interact and one of them closes the
device and later re-opens it.

67399e35ff Fix wrong offset calculation in snd_pcm_{read|write}_mmap() 
The offset used in snd_pcm_{read|write}_mmap() is not the linear offset
but the offset in a ring buffer.  It has to be rounded.

the next-available one (-1) as the default number.  Now it's set to 0.

e23317de39 Allow empty pythonincdir option

the standard header path.  So, configure shouldn't check its emptiness.

dac0e3b17c Handle "Input Source" as a capture element 
Some drivers use "Input Source" as the capture source mixer element because
mixer abstraction layer can't handle multiple "Capture Source" elements.
This patch adds a hack to handle Input Source as a capture route, and let
mixer apps know that it's a capture stuff, at least.

679ae1c7f2 Continue build even if python-config doesn't exist 
It's annoying that the configure script stops with an error if
python-config doesn't exist.  It's no fatal error, so the configure
should disable the python components and continue.

9749c31fa7 cmi8788: add alsa-lib config

c7e1676dcd Don't set PCM pointer at error in snd_pcm_hw_open()

e0d7bfcea6 mixer simple basic abstraction - added python binding 
reasons:
- rapid development
- class-like code structure
- more readable code
features:
- hcontrol binding is managed from python (opportunity to create
  virtual mixer without driver or join multiple cards to behave as one)

e4c80614e9 Use S16_BE as dmix format for PPC drivers 
PPC drivers should use S16_BE as the base format of dmix/dsnoop.

267d7c7281 Add support of little-endian on i386/x86_64 dmix 
i386/x86_64 alsa-lib may need to handle big-endian formats, e.g.
when running via qemu on PPC.  The generic dmix code already has
both endian support, so let's use it as fallback.
