History
Ulf Lilleengen d8d015cddc - Split up the BIO queue into a queue for new and one for completed requests. 
This is necessary for two reasons:
  1) In order to avoid collisions with the use of a BIOs flags set by a consumer
     or a provider
  2) Because GV_BIO_DONE was used to mark a BIO as done, not enough flags was
     available, so the consumer flags of a BIO had to be misused in order to
     support enough flags. The new queue makes it possible to recycle the
     GV_BIO_DONE flag into GV_BIO_GROW.
  As a consequence, gvinum will now work with any other GEOM class under it or
  on top of it.

- Use bio_pflags for storing internal flags on downgoing BIOs, as the requests
  appear to come from a consumer of a gvinum volume. Use bio_cflags only for
  cloned BIOs.
- Move gv_post_bio to be used internally for maintenance requests.
- Remove some cases where flags where set without need.
