ucm: add LibraryConfig support

2021-04-13T15:14:28+00:00

This commit allows to define private alsa-lib's configuration. When
the configuration is present, the device values ("PlaybackCTL",
"CaptureCTL", "PlaybackMixer", "CaptureMixer", "CapturePCM")
are prefixed with '_ucmHEXA.' string where HEXA is replaced by the
unique hexadecimal number identifying the opened ucm manager handle.

    Syntax 4

    LibraryConfig.a_label.SubstiConfig {
            # substituted library configuration like:
            usr_share_dir "${ConfLibDir}"
    }

    LibraryConfig.b_label.Config {
            # non-substituted library configuration like:
            usr_share_dir "/usr/share/alsa"
    }

    The File counterparts:

    LibraryConfig.c_label.SubstiFile "/some/path"
    LibraryConfig.d_label.File "/some/path"

Note that for files the contents is substituted on the request,
but the file name is always substituted (useful for ${ConfDir} etc.).

The private configuration is not saved or preserved. It's life time
belongs to the opened ucm manager handle.

seq: Fix signedness in MIDI encoder/decoder

2018-08-23T06:34:37+00:00

The qlen field of struct snd_midi_event was declared as size_t while
status_events[] assigns the qlen to -1 indicating to skip.  This leads
to the misinterpretation since size_t is unsigned, hence it passes the
check "dev.qlen > 0" incorrectly in snd_midi_event_encode_byte(),
which eventually results in a memory corruption.

Also, snd_midi_event_decode() doesn't consider about a negative qlen
value and tries to copy the size as is.

This patch fixes these issues: the first one is addressed by simply
replacing size_t with ssize_t in snd_midi_event struct.  For the
latter, a check "qlen <= 0" is added to bail out; this is also good as
a slight optimization.

core: Proper reference of internal snd_dlopen()

2018-01-04T14:29:57+00:00

snd_dlopen() was recently rewritten to be versioned symbols, and we
have to call it with INTERNAL() wrapper from the library itself.

Add the proper declaration in the local header and fix the callers
appropriately.

Change snd_dlopen() function to return the error string

2017-11-27T20:48:20+00:00

The dlopen() function might fail also for another reason than
a missing file, thus return the error string from dlerror().

seq: fix snd_seq_set_queue_tempo() usage example in the documentation

2017-10-03T07:11:44+00:00

snd_seq_set_queue_tempo() requires a queue id as the second argument,
fix the example in documentation to reflect that.

Also add the queue id as an argument of the set_tempo() function, just
to keep the whole example compilable.

cleanup: fix poll.h includes

2017-07-12T10:05:37+00:00

According POSIX[1] and linux manpage[2] the include is poll.h, not
sys/poll.h.

This fixes the he following compiler warning when build with musl libc:

  /usr/include/sys/poll.h:1:2: warning: #warning redirecting incorrect #include  to  [-Wcpp]
   #warning redirecting incorrect #include  to 
    ^~~~~~~
