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:
+ Name the programs installed by the db(2) package db2_*.

+ Put documentation under ${PREFIX}/share/doc instead of
  ${PREFIX}/share/doc/html.  Packages that install documentation under the
  "html" directory are supposed to move them to the "doc" \ 
directory when
  they're updated, but these packages are basically EOL'ed so just move
  them now.

+ Add full DESTDIR support.

Bump the PKGREVISION of databases/db to 3 and databases/db3 to 4.

Log message:
Replace mk/bsd.prefs.mk includes with bsd.fast.prefs.mk includes.
The redundant parsing of bsd.prefs.mk is mostly avoided now and
parse time e.g. for x11/kdebase3 gets reduced by up to 10%.
