Subject: 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.
