libbarrelfish: Spilt private waitset_chan.h header into a public and private
header.

* Check all files that included the old header, if the need the private or the
public header or both or none at all. Some files included the header but
didn't use any of the functions provided by the header.

* Change libahci so that it no longer uses the libbarrelfish-private header.

Refactored libcollections.a to prefix all exported functions and data
types with collections_ to prevent namespace pollution. Many
application programs have their own functions named list_* and hash_*
(e.g. PostgreSQL).

simplify out-of-band cap transfer to avoid asynchronously reporting errors back to the sender

As discussed on the mailing list (10.01.2012 "Proposed change to
out-of-band cap transfer"), this change changes the semantics so that
an error in delivery of the cap is reported to the receiver (rather
than asynchronously to the sender) along with a NULL capref. This
simplifies the implementation within the monitor, and results in saner
error handling on both sides.
