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.

TRE is a lightweight, robust, and efficient POSIX compliant regexp matching library with some exciting features such as approximate (fuzzy) matching. At the core of TRE is a new algorithm for regular expression matching with submatch addressing. The algorithm uses linear worst-case time in the length of the text being searched, and quadratic worst-case time in the length of the used regular expression. In other words, the time complexity of the algorithm is O(M2N), where M is the length of the regular expression and N is the length of the text. The used space is also quadratic on the length of the regex, but does not depend on the searched string. This quadratic behaviour occurs only on pathological cases which are probably very rare in practice.

Over 1200 files touched but no revisions bumped :) RECOMMENDED is removed. It becomes ABI_DEPENDS. BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo. BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo. BUILDLINK_DEPENDS does not change. IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS which defaults to "yes". Added to obsolete.mk checking for IGNORE_RECOMMENDED. I did not manually go through and fix any aesthetic tab/spacing issues. I have tested the above patch on DragonFly building and packaging subversion and pkglint and their many dependencies. I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I have used IGNORE_RECOMMENDED for a long time). I have been an active user of IGNORE_RECOMMENDED since it was available. As suggested, I removed the documentation sentences suggesting bumping for "security" issues. As discussed on tech-pkg. I will commit to revbump, pkglint, pkg_install, createbuildlink separately. Note that if you use wip, it will fail! I will commit to pkgsrc-wip later (within day).

Make pkglint happy about the comment in the Makefile Add an extra CPPFLAGS to the bl3.mk to ensure the correct regexp files are picked up by any package that requires this one. From Aleksey Cheusov.
