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 is the enhancements of rawmidi API for the new feature added in
6.14 kernel: the indication of a tied device and the inactive flag for
the selected substream.
The new function is added for obtaining the tied device,
snd_rawmidi_info_get_tied_device().
And the new bit flag is defined for indicating the inactive
substream, SNDRV_RAWMIDI_INFO_STREAM_INACTIVE, which is exposed via
snd_rawmidi_info_get_flags().

Some applications seem including alsa/seqmid.h individually, and this
got broken with the update of alsa-lib because now we have

internally. Also, add the inclusion of rawmidi.h in ump.h for similar
reasons.

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.

snd_seq_create_ump_block() receives a snd_ump_block_info_t data at the
creation of a FB and updates its associated sequencer port, but it
handled the port direction incorrectly. The UMP / port direction
means the connectivity, but the current code translated other way
round. The correct translation should be that input = receiver, i.e.
a writable port for applications, and output = source, a readable port
for applications.
This patch corrects the translation, and add more comments to the
direction definition.

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.

For making it easer for applications to create a virtual UMP Endpoint
and UMP blocks, add two API helper functions.
snd_seq_create_ump_endpoint() creates (unsurprisingly) a UMP Endpoint,
based on the given snd_ump_endpoint_info_t information. The number of
(max) UMP groups belonging to this Endpoint has to be specified.
This function sets up the Endpoint info on the sequencer client, and
creates a MIDI 2.0 UMP port as well as UMP Group ports automatically.
The name of the sequencer client is updated from the Endpoint name,
too.
After creating a UMP Endpoint, create each UMP Block via
snd_seq_create_ump_block() function with a snd_ump_block_info_t info.
The associated groups for each block have to be specified there.
The port names and capability bits are updated accordingly after
setting each block information.
