- Rework the way thread ordering is enforced so that it actually behaves as
  expected (issue discovered during detailed testing). Ordering is now an
  off-by-default option that can be enabled at ALQ creation time using the
  ALQ_ORDERED flag.

- Add an alq_open_flags() KPI call to allow the new ALQ_ORDERED flag to be
  specified. alq_open() is now implemented as a wrapper around alq_open_flags.

- Rename alq_postn() to alq_post_flags() to keep the naming consistent.

- Keep a record of some useful debugging printf's (will be removed in a later
  diff).

- Remove some no longer relevant assertions.

- Introduce the AQ_VARLEN flag, used internally to indicate the ALQ is variable
  length message capable.

- Protect alq_getn/alq_post from 0 length writes so that the "use less than you
  asked for" feature works in contexts where no data may be generated.
