Remove some more *LEGACY* settings that are over a month old and

Changes 2.1.10:
  I. IMPORTANT BUG FIXES
    - The size comparison for BDF and PCF files could fail sometimes.
    - Some  CFF files  were still not  loaded  correctly.   Patch from
      Derek Noonburg.
    - The stroker still had some serious bugs.
    - FreeType didn't properly parse empty Type 1 glyphs.
    - An unbound dynamic buffer growth was fixed in the PFR loader.
    - Several bugs have been fixed in the cache sub-system.
    - The auto-hinter didn't work properly for fonts without a Unicode
      charmap -- it even refused to load the glyphs.
  II. IMPORTANT CHANGES
    - Many fixes have been applied to drastically reduce the amount of
      heap   memory   used   by   FreeType,   especially   when  using
      memory-mapped font files  (which is the default on Unix  systems
      which support them).
    - The auto-hinter  has been replaced with a new module, called the
      `auto-fitter'.  It consumes  less memory  than its  predecessor,
      and it is  prepared to support non-latin scripts  better in next
      releases.
    - George Williams  contributed code to read  kerning data from PFM
      files.
  III. MISCELLANEOUS
    - The BDF driver  no longer converts  all returned bitmaps  with a
      depth of 2bpp or 4bpp to a depth of 8bpp.
    - A new option `--ftversion' has been  added to freetype-config to
      return the FreeType version.
    - The  memory  debugger  has  been  updated   to  dump  allocation
      statistics on  all allocation  sources in the library.

Makefile cleanup to close PR#30492

Log message:
Coalesce the common makefile code in the builtin.mk file that inspect
the X11 distribution using imake into mk/buildlink3/imake-check.mk.
imake-check.mk calls out to a helper shell script mk/buildlink3/imake-check
that generates the required Imakefiles and runs imake.  Remove the
now extraneous builtin-imake.mk files as the builtin.mk files can now
contain the name of the imake symbol to check.

Log message:
Only check for the existence of the first word of ${IMAKE} since it may
contain a command plus arguments.  We use the standard idiom to extract
the first word of a list stored in a make variable:

	VAR_CMD=	${VAR:C/^/_asdf_/1:M_asdf_*:S/^_asdf_//}

XXX This can be replaced with a more succinct use of variable modifiers
XXX when we update the bootstrap bmake to match the latest NetBSD make
XXX sources, i.e.:
XXX
XXX	VAR_CMD=	${VAR:[1]}

Log message:
Don't require a read-write pkgsrc tree when invoking imake.  We avoid
this requirement by using TMPDIR as the read-write location demanded
by using imake.

Log message:
Use IMAKE_MAKE instead of MAKE to process the makefile generated by imake.

Log message:
Massive cleanup of buildlink3.mk and builtin.mk files in pkgsrc.
Several changes are involved since they are all interrelated.  These
changes affect about 1000 files.

The first major change is rewriting bsd.builtin.mk as well as all of
the builtin.mk files to follow the new example in bsd.builtin.mk.
The loop to include all of the builtin.mk files needed by the package
is moved from bsd.builtin.mk and into bsd.buildlink3.mk.  bsd.builtin.mk
is now included by each of the individual builtin.mk files and provides
some common logic for all of the builtin.mk files.  Currently, this
includes the computation for whether the native or pkgsrc version of
the package is preferred.  This causes USE_BUILTIN.* to be correctly
set when one builtin.mk file includes another.

The second major change is teach the builtin.mk files to consider
files under ${LOCALBASE} to be from pkgsrc-controlled packages.  Most
of the builtin.mk files test for the presence of built-in software by
checking for the existence of certain files, e.g. <pthread.h>, and we
now assume that if that file is under ${LOCALBASE}, then it must be
from pkgsrc.  This modification is a nod toward LOCALBASE=/usr.  The
exceptions to this new check are the X11 distribution packages, which
are handled specially as noted below.

The third major change is providing builtin.mk and version.mk files
for each of the X11 distribution packages in pkgsrc.  The builtin.mk
file can detect whether the native X11 distribution is the same as
the one provided by pkgsrc, and the version.mk file computes the
version of the X11 distribution package, whether it's built-in or not.

The fourth major change is that the buildlink3.mk files for X11 packages
that install parts which are part of X11 distribution packages, e.g.
Xpm, Xcursor, etc., now use imake to query the X11 distribution for
whether the software is already provided by the X11 distribution.
This is more accurate than grepping for a symbol name in the imake
config files.  Using imake required sprinkling various builtin-imake.mk
helper files into pkgsrc directories.  These files are used as input
to imake since imake can't use stdin for that purpose.

The fifth major change is in how packages note that they use X11.
Instead of setting USE_X11, package Makefiles should now include
x11.buildlink3.mk instead.  This causes the X11 package buildlink3
and builtin logic to be executed at the correct place for buildlink3.mk
and builtin.mk files that previously set USE_X11, and fixes packages
that relied on buildlink3.mk files to implicitly note that X11 is
needed.  Package buildlink3.mk should also include x11.buildlink3.mk
when linking against the package libraries requires also linking
against the X11 libraries.  Where it was obvious, redundant inclusions
of x11.buildlink3.mk have been removed.

Log message:
Packages have no business modifying PKG_DEFAULT_OPTIONS -- it's a
user settable variable.  Set PKG_SUGGESTED_OPTIONS instead.  Also,
make use of PKG_OPTIONS_LEGACY_VARS.
