Drop maintainership.

Log message:
Whitespace cleanup, courtesy of pkglint.
Patch provided by Sergey Svishchev in private mail.

Log message:
DESTDIR support.

Log message:
* Honor PKGINFODIR.
* List the info files directly in the PLIST.

Log message:
* Teach the tools framework how to supply the pkgsrc version of
  makeinfo if no native makeinfo executable exists.  Honor TEXINFO_REQD
  when determining whether the native makeinfo can be used.

* Remove USE_MAKEINFO and replace it with USE_TOOLS+=makeinfo.

* Get rid of all the "split" argument deduction for makeinfo since
  the PLIST module already handles varying numbers of split info files
  correctly.

NOTE: Platforms that have "makeinfo" in the base system should check
      that the makeinfo entries of pkgsrc/mk/tools.${OPSYS}.mk are
      correct.

Log message:
Remove some unnecessarily strong dependencies on perl that resulted
from including perl5/buildlink3.mk.  These packages just need the Perl
interpreter, and can just add "perl" to USE_TOOLS instead.

Log message:
Drop support for TOOLS_DEPMETHOD.<tool>.  The new way to specify a
run-time dependency (DEPENDS) on a tool is to append a ":run" modifier
to the tool name, e.g.,

	USE_TOOLS+=	perl:run

Tools without modifiers or with an explicit ":build" modifier will
cause build dependencies (BUILD_DEPENDS) on those tools to be added.
This makes the notation a bit more compact.

Log message:
Remove explicit dependencies on the GNU m4 package with USE_TOOLS+=m4
and appropriate TOOLS_DEPMETHOD.gm4 settings.

Log message:
Change references to M4 & YACC into TOOLS_M4 & TOOLS_YACC to simplify
transition to new tools framework.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.
