sound fixes for 4.5-rc3

Browse Source 
This was a busy week and I had to prepare a pile of duct tapes for
 the bugs reported by syzkaller fuzzer in wide range of ALSA core
 APIs: timer, rawmidi, sequencer, and PCM OSS emulation.  Let's see
 how many other holes we need to plug.
 
 Besides that, a few usual boring stuff, HD- and USB-audio quirks,
 have been added.
