remove mesa < 18 support

Fix "build.sh syspkgs" build error

branches: 1.46.2;
Reintroduce the support of MKCATPAGES

Requested by <mrg>

Remove catman pages support

No longer relevant after the MKCATPAGES removal.

Sort and deduplicate set lists.

Give syspkg names to xserver without machine dependet files

Give syspkg names to xserver mi files

enable EGL and glamor. partly from maya@.

for x86 and evbarm:
- install headers and libEGL
- install xorg-server glamoregl component
- link xorg drivers against gbm/egl

bonus fix:
- fix some wrongly marked compatx11file files


build tested on shark, sgimips, evbarm64-el, amd64 and i386.
run tested on radeon, intel and nvidia on amd64, including
'modesetting' driver on amd64. however, my systems disable
it due to llvmpipe so i'm not sure what is happening.

properly mark libmesa_dri.so obsolete in mesa18 x86 builds.

libmesa_dri.so is obsolete in mesa18 for x86 as well.

branches: 1.38.14;

More sets list sorting (maybe this time they're really all done)

remove all the X11R6 (old xfree86) entries.

a technically more correct solution would be to mark all but the
shared libraries obsolete, but with approximately 10000 entries
it would significantly slowdown postinstall obsolete checking
and as an end-user, i'm not sure i'd want it anyway.

this also makes it much easier to automate X11R7 changes ;-)

branches: 1.36.2;
move the obsolete list files into their respective sets. this means
that if you install a new set and run "postinstall fix obsolete"
the expected things happen.

(hi 12.5 year old me who thought base was better than etc set, which
it really was, but this is better again :-)

sets.subr:
support machine=<xxx>, machine_arch=<xxx>, machine_cpu=<xxx> tags.

dri7: build Mesa 7 r300_dri.so for x86 platforms.

update sets and reachover makefiles for mesa 10.3.5.

branches: 1.33.10;
libmesa needs the lib prefix because it is used in LIBDPLIBS

branches: 1.32.4; 1.32.10;
move xorg-server.m4 into the MD files that build xorg-server.
this should fix most of the recent build issues on xorg without
xorg-server platforms.

move xorg-server.m4 into the xserver set, and mark it 'xorg'.

fixes non-xorg-server builds.

- build mesa_dri and swrast on all platforms
- kill imstt
- re-add int10 on macppc

merge all the changes for xorg-server 1.6

Try to cleanup the sets to allow ports without X11R7 servers to build:
- Xnest is mi, cvt and gtf are not
- Man pages are (mostly) mi

As all port now build Xvfb, move it into the mi file.
Remove any empty md.* files (but leave ad.*)

branches: 1.26.2; 1.26.4; 1.26.8;
Use "-obsolete-" instead of "-unknown-" as the syspkg tag for obsolete entries.
Suggested by Alan Barrett <apb>

* reformat the (non-comment) columns
* use "-unknown-" as the syspkg tag for obsolete entries for consistency
with in-use entries
* remove pointless "obsolete" X11R7 entries

remove x11 entry for XF86Config.5 since it is not mi
discovered by: Juergen Hannken-Illjes while building evbppc

add entries for ./etc/mtree/set.x{server,font,etc} when MKXORG=yes

Entries for HTML man pages generated with MKHTML=yes.
PR 29233

add the last of the xorg list entries

- add x11 tag to all entries
- add most of the entries required for xorg (with xorg tag)

branches: 1.19.2; 1.19.6; 1.19.10;
Add a note about marking entries as "obsolete", instead of deleting them.

branches: 1.18.8;
White space nits.

rename 2 installed files in xsrc which may have case conflicts in $DESTDIR
/usr/X11R6/bin/xdmx -> /usr/X11R6/bin/dmx
/usr/X11R6/include/X11/bitmaps/Stipple -> /usr/X11R6/include/X11/bitmaps/Stippler

Add Xdmx server, libraries and utilities to reachover set lists.

Update reachover build framework set list for XFree86 4.5.0.

branches: 1.14.4; 1.14.10;
Eliminate a lot of redundancy here. Xnest is built on every platform..So it
goes in mi

Add ./etc/mtree/set.<setname> entry for each set.

Implement `xetc' set to contain configuration that may be changed by
the end-user that we don't want to overwrite when extracting the
other X sets.

remove unnecessary directory

Add support for MKCATPAGES=no MKMAN=no MKMANZ=yes MKLINT=no.
Remove unnecessary entries for directories.
Move some catman pages from xbase -> xserver, to match the man pages.

move xvidtune to xserver/mi since it's installed by all machines

XXX we may want to not install it at all, but this is better than
having it spread across xbase for some machines and xserver
for others in various md.<mach> files.

x11 set lists mi and md.i386

Separate out the X sets:
* sets for xsrc/xc (XF 3.x)
xbase3 xcomp3 xcontrib3 xfont3 xmisc3 xserver3
* sets for xsrc/xfree/xc (XF 4.x)
xbase4 xcomp4 xcontrib4 xfont4 xmisc4 xserver4
* sets for src/x11 (reachover build of xsrc/xfree/xc):
xbase xcomp xcontrib xfont xmisc xserver
(note: not populated yet, and not to be shared by x*3 or x*4 anymore)

Move X11R6/lib/X11/xserver/SecurityPolicy from xbase set to xserver set.
It is installed only if BuildServer == YES.

Add a NetBSD RCS tag to each distrib list file.

Move some MI stuff to i386 MD files, courtesy of the broken config
files for other ports.

Add various missing files.

To be consitent with the other sets:
- use ./usr and not usr
- remove duplicated directory entries

branches: 1.1.2;
Add MI and mac68k-specific X11 set lists.
