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.
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).
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.
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)
Added --with-configdir and --with-plugindir options to configure
which specify the directories for config files and plugin objects
respectively. The default paths when these options are not
specified are unchanged.
Added --enable-symbolic-functions configure option. This will detect
and pass -Bsymbolic-functions linker option, which gives you better
performance and smaller binary size. Only recent binutils supports
this option.
- add long card name to device description
- create empty PCM plugin to allow right hint description parsing
- reorder devices in alsa.conf
- make namehint more configurable (using default.namehint.showall switch)
- add two levels basic and exteded for hints to default configuration files
- do not show direct device aliases
- removed all known memory leaks
the current configure script assumes that it will be run in the srcdir ... i
often build things out of tree so you can quickly punt all the generated
files:
mkdir build
cd build
../configure
cd ..
rm -r build
clean!
this tweaks the configure script in a few places to use the correct variable
instead of assuming that configure is always in $PWD ...
i say "sort of" in the subject because there is still the issues of the pcm
symbols list being generated in $builddir instead of $srcdir and the alsa
include symlink, but these doesnt really concern me for what i need ;)

See: bug#2274
checking for versioned symbols... ./configure: line 19347: test: "1: integer
expression expected
./configure: line 19350: test: "1: integer expression expected
This is caused by my libtool VERSION string:
VERSION="1.5.22 Debian 1.5.22-2"
The test in configure.in can't currently deal with the quotes.

some architectures, like Blackfin, have a prefix added to all symbols (in our
case it's historical baggage)
while normally packages shouldnt care, when code starts mixing assembler with
C (like symbol versioning), you need to dip down into the inner details.
find attached a patch which queries gcc for the prefix (all gcc toolchains
have a builtin define of __USER_LABEL_PREFIX__) and then automatically has
asm() constructs utilize this
since most targets define __USER_LABEL_PREFIX__ to nothing, hopefully this
shouldnt cause any problems :)
Add configuration options to change the default device path from the
default /dev/snd. This is useful for embedded systems that do not want
subdirectories in /dev.
