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.

+ The termlib.buildlink3.mk file is meant to be included by packages that need basic termlib functionality, i.e. tgetent(), tgoto(), tputs(), etc. Together with the termlib.builtin.mk file, they will use either a built-in termcap library, a built-in X/Open "enhanced" curses library, or ncurses to provide these functions. + Add BUILDLINK_LIBNAME.* definitions to the various curses buildlink3.mk and builtin.mk files that give the "base" library name of the curses library, e.g. curses, ncurses, etc. These are used by the termlib files to set BUILDLINK_LIBNAME.termlib.

Instead of just looking at the libraries, we check for the headers as well, and if multiple implementations exist (usually because of symlinks to shared libraries), then we order the search as: tinfo, curses, termcap, termlib, c

+ Fix error in previous commit -- too much of the termcap buildlink code was moved to the builtin.mk file.
