Examples:
"debug" - Set global level to debug
"3" - Set global level to 3 (info)
"info,pcm:debug" - Set global to info, pcm to debug
"error,mixer:5,pcm:4" - Set global to error, mixer to 5 (trace), pcm to 4 (debug)

Add priority level and interface classifiers. Define macros
for all priority level types to keep the callers more readable.
Ensure the compatibility with previous logging mechanism.

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.

Change @SYMBOL_PREFIX@snd_has_tempo_base to
@SYMBOL_PREFIX@snd_has_queue_tempo_base.
Starting with version 1.2.13, alsa-lib fails to link with ld.lld-19 due
to "version script assignment of 'ALSA_1.2.13' to symbol
'snd_seq_has_tempo_base' failed: symbol not defined".
Per commit 769d1db1b0 the correct name for
the symbol is @SYMBOL_PREFIX@snd_has_queue_tempo_base; therefore, update
src/Vesions.in.in to match.
Fixes bug #420
Fixes Gentoo bug 943399 (https://bugs.gentoo.org/943399)

Implement the API function calls corresponding to the new sequencer
port flag bit that has been added recently to the kernel.
A UMP MIDI 2.0 device allow to have an optional MIDI 1.0 port while
speaking in MIDI 2.0 protocol for other UMP Groups. The new seq port
flag indicates that.
This is rather a minor difference, and since ALSA sequencer core
covers the all conversions, usually you don't have to worry about it
at all.

MIDI2 Set Tempo message uses 10ns-based values, and we need to update
the API to change the base time unit.
This patch adds a few new API functions:
- snd_seq_has_queue_tempo_base() returns 1 if the client supports a
new tempo-base value; if 0, it's an old system and application has
to use the tempo in the fixed 1us unit
- the tempo base can be changed with
snd_seq_queue_tempo_set_tempo_base(), provided in nsec unit;
the value has to be either 10 or 1000 (or 0 as default, equivalent
with 1000)
The protocol version is checked and fallback to the fixed 1us base for
the old clients.

Configure script allows for the disabling of the pcm module. When
disabled, the pcm symbols will not be available. Add guards to remove
symbols from version map when not present.
