snd_seq_parse_address() uses strncmp() to compare the client name
in the string argument with the existing clients, until it finds one
name matching the same leading characters. This may produce wrong
results when there are two sequencer clients with similar names.
Example: "KMidimon" : "Kmid"

When decoding (N)RPN sequencer events into raw MIDI commands, the
extra_decode_xrpn() function had accidentally swapped the MSB and LSB
controller values of both the parameter number and the data value.

Running status cannot be using in the command immediately following
a system exclusive command, so we have to reset the running status
state in that case.

Since they are never changed it does not make sense to have them in
the writeable .data section, just make sure to add const to the ops
member in the structure definitions so that there are no extra
warnings added.

By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.
The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

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.
Reset the event type after encoding a system message to prevent any
following data bytes from being interpreted as data for a running status
system message, which is not allowed in MIDI.
Create a new state ST_INVALID for the encoder to prevent data bytes at
the beginning of a stream or after a sysex message being interpreted as
note-off parameters.
Add four new information flags SNDRV_SEQ_PORT_TYPE_HARDWARE, _SOFTWARE,
_SYNTHESIZER, _PORT for sequencer ports. This makes it easier for apps
like Rosegarden to make policy decisions based on the port type.
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.
Remove several memory leaks by not aborting prematurely from a
snd_xxx_close() function when some operation fails.
This can happen when a USB device was unplugged.
Added --disable-aload configure option to suppress probing of
/dev/aload* files for auto-loading. These files often conflict with
udev mechanism.
Also, --with-resmgr is changed to --enable-resmgr.

- increased the protocol version to 1.0.1.
