[alsa-devel] changes in hda-emu kernel code management

Hi,

right now I changed the way to manage the kernel code in hda-emu slightly, and pushed out the commits.

Formerly, each kernel file (hda_*.[ch] and patch_*.c) is symlinked to kernel/ subdirectory in configure script, and it's built there. Now, instead of creating each symlink, a master symlink is created as a subdirectory hda, and the build is done in kernel/*.c which includes "../hda/xxx.c". This makes easier to switch between repos, also little messy.

If you find any regression by this change, let me know.
