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.

Initial import of libsigsegv-2.2 from pkgsrc-wip, packaged by Martijn van Buul. GNU libsigsegv is a library for handling page faults in user mode. A page fault occurs when a program tries to access a region of memory that is currently unavailable. Catching and handling a page fault is a useful technique for implementing: * Pageable virtual memory * Memory-mapped access to persistent databases * Generational garbage collectors * Stack overflow handlers * Distributed shared memory

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).
