ALSA: seq: Reorganize kconfig and build

Browse Source 
This is a slightly intensive rewrite of Kconfig and Makefile about
ALSA sequencer stuff.

The first major change is that the kconfig items for the sequencer are
moved to sound/core/seq/Kconfig.  OK, that's easy.

The substantial change is that, instead of hackish top-level module
selection in Makefile, we define a Kconfig item for each sequencer
module.  The driver that requires such sequencer components select
exclusively the kconfig items.  This is more straightforward and
standard way.

Say Y or M to enable MIDI sequencer and router support. This

Many programs require this feature, so you should enable it

Say Y here to enable the dummy sequencer client. This client

You don't need this unless you want to connect many MIDI

To compile this driver as a module, choose M here: the module
will be called snd-seq-dummy.
