Log message:
Update to 0.72. From the release announcement:

This is a bugfix release to address a few reported issues and also a few
issues that were discovered via my own testing.

    * Add a helper method which ensures all data is flushed to disk
    * Added additional error handling to prevent malformed DHT messages
      crashing the library
    * Fixed issue when zeroing unused bits for torrents with an exact
      multiple of 32 pieces
    * Fixed issue where data could be written to the wrong file if a file
      with the same name existed in multiple torrents
    * Fixed the handling of torrents where the last file(s) are of zero
      length
    * Fixed regression with global download rate limiting
    * Fixed a performance regression with the new piece picking pipeline
      which resulted in lots of CPU cycles being used up on peers which
      have not sent an unchoke message

OK'ed by wiz@ (as was the textproc/icu update).

Log message:
Simply and speed up buildlink3.mk files and processing.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

Log message:
Needs pkg-config. Prefer bsdtar over gtar. Mark as destdir usable.
