Install of the alsalisp binary has been disabled since 2006 (in commit
8d382ccd), and building of it was disabled by default in 2018 (in commit
32ceab21), so it is reasonable to assume that nobody is using it.
Use within the alsa-lib project is limited to an aliases file that looks
like it is intended as an example, plus some very small .alisp files
associated with the SiS SI7018 PCI sound card which has not been
manufactured in years. These too have not been installed since 2018 when
commit 32ceab21 disabled building of the alsalisp binary.
In preparing this change, I searched the Github issue tracker for
"lisp", "alisp" and "alsalisp", and found no complaints about the above
changes. I also did a Github code search for projects that might be
including the `alisp.h` header and found none. Therefore I think this
code can be safely deleted and nobody is likely to object.

Fixes several issues with header files:
- prefer alsa/asoundlib.h file for the alsa-lib core functionalities
(use #warning to inform current and future developers, do the job)
- include alsa/asoundlib.h in headers for external plugins by default
- pcm_external.h: dependencies cleanup
- as benefit, the parsers in IDEs should get all information for individial
header files (see PR#435)
This change was mainly tergetted to fix errors caused by wrong include order
(like for endianness detection, missing typedefs etc.).

This patch adds the initial support for UMP rawmidi access.
It's merely the wrapper for the standard rawmidi to access to the UMP

Fixes:
cd alsa-lib
if test -r Makefile; then
make distclean
fi
mkdir build
cd build
../configure
make
Note:
The srcdir is used for the symlinks to generated include files :-(
I've not found a better (easy) way to fix this.

We used to put the additional include path $includedir/alsa in
pkgconfig just because some applications have included asoundlib.h
like
#include <asoundlib.h>
although the canonical form should be
#include <alsa/asoundlib.h>
However, adding this include path is significantly dangerous due to
possible conflicts of file names like version.h. It's already the
reason to discourage people using alsa.pc for the packages.
In this patch, the additional include path from alsa.pc is dropped
finally. At the same time, as a rescue plan for the programs
including via <asoundlib.h>, a stub header file is provided in
include/sound/asoundlib.h. It just includes alsa/asoundlib.h with a
warning to suggest for replacing with alsa/asoundlib.h.
Actually this is the same file as we install into sys/asoundlib.h, so
the whole changes are very minimal here.

We've had a few home brew atomic operations in a couple of places in
the PCM code. This was for supporting the concurrent accesses, but in
practice, it couldn't cover the race properly by itself alone.
Since we have a wider concurrency protection via mutex now, we can get
rid of these atomic codes, which worsens the portability
significantly.

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.
Created a new rate converter plugin SDK.
A rate converter can be replaced as an extra plugin now.
The default rate converter is a built-in linear converter.
You can find a sample external converter in alsa-plugins package.
Fixed the compilation on a system with old alsa-lib headers.
A symlink alsa is created here to include all alsa-lib headers
locally even via #include <alsa/xxx.h>
- exported all necessary functions to create a mixer module outside alsa-lib
- separated simple mixer API from the simple mixer implementation
(using callbacks as usuall)
- src/mixer/simple.c is the core
- src/mixer/simple_none.c is the current (no-abstraction) implementation
based on control names; note that this module does not depend on
internal ALSA structures now
- src/mixer/simple_abst.c is the ongoing abstraction which will use
external dynamic modules; src/conf/smixer.conf will describe which
modules will be used depending on the components from the driver
New snd_pcm_hw_params_* functions are available only explicitly when
ALSA_PCM_NEW_HW_PARAMS_API is defined.
Updated documentation and test code to new API.
- added backward compatibility for older non-compatible functions
- added --with-compat-rc3 to configure script to build library
backwards compatible with 0.9.0rc3
- added symbol versioning like libc.so.6
- ALSA_0.9 - alsa base
- ALSA_0.9.0rc4 - first set of new functions (snd_pcm_hw_params_*)
