1191   This single function is key to pretty much everything.  The pvrusb2
1192   device can logically be viewed as a series of subsystems which can be
1193   stopped / started or unconfigured / configured.  To get things streaming,
1194   one must configure everything and start everything, but there may be
1195   various reasons over time to deconfigure something or stop something.
1196   This function handles all of this activity.  Everything EVERYWHERE that
1197   must affect a subsystem eventually comes here to do the work.
1198
1199   The current state of all subsystems is represented by a single bit mask,
1200   known as subsys_enabled_mask.  The bit positions are defined by the
1201   PVR2_SUBSYS_xxxx macros, with one subsystem per bit position.  At any
1202   time the set of configured or active subsystems can be queried just by
1203   looking at that mask.  To change bits in that mask, this function here
1204   must be called.  The "msk" argument indicates which bit positions to
1205   change, and the "val" argument defines the new values for the positions
1206   defined by "msk".
1207
1208   There is a priority ordering of starting / stopping things, and for
1209   multiple requested changes, this function implements that ordering.
1210   (Thus we will act on a request to load encoder firmware before we
1211   configure the encoder.)  In addition to priority ordering, there is a
1212   recovery strategy implemented here.  If a particular step fails and we
1213   detect that failure, this function will clear the affected subsystem bits
1214   and restart.  Thus we have a means for recovering from a dead encoder:
1215   Clear all bits that correspond to subsystems that we need to restart /
1216   reconfigure and start over.
