Log message:
Libtool fix for PR pkg/26633, and other issues.  Update libtool to 1.5.10
in the process.  (More information on tech-pkg.)

Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.

Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.

Log message:
Mechanical changes to package PLISTs to make use of LIBTOOLIZE_PLIST.
All library names listed by *.la files no longer need to be listed
in the PLIST, e.g., instead of:

	lib/libfoo.a
	lib/libfoo.la
	lib/libfoo.so
	lib/libfoo.so.0
	lib/libfoo.so.0.1

one simply needs:

	lib/libfoo.la

and bsd.pkg.mk will automatically ensure that the additional library
names are listed in the installed package +CONTENTS file.

Also make LIBTOOLIZE_PLIST default to "yes".

Log message:
Rework the way the kaffe packages work:
- Make kaffe the main package, on which others can depend, and which has no
  support for things like sound nor graphics.  Bump its revision to 2.
  While here, do some cleanup too.
- Add a kaffe-x11 package, that installs on top of kaffe, and which provides
  the library needed for AWT support through X11.
- Add a kaffe-esound package, that installs on top of kaffe, and which provides
  the library needed for sound support through esound (i.e., no more need for
  the USE_ESOUND variable here).
- Remove the kaffe-nox11 package.
