clean up COMPAT_* options for native netbsd code:
- new series of files that are useful for saying "i want everything
since netbsd 1.4", etc.
- use the fact COMPAT_* options have future dependancies to remove
many redundant options.

removes about 3000 lines total across kernel configuration files.
tested about 30 random kernels in the changed list.

Remove TCP_COMPAT_42 from the config files. Pass 2.

branches: 1.32.2;
Systematize (and in many cases, fix) the comments on options COMPAT_NN.

There are quite a few configs that are missing some COMPAT_NN options
in ways that don't make sense; this should probably get cleaned up
too, but for the time being I've not added or removed anything.

Use COPTS="-O2 -fno-reorder-blocks" as defined in sys.mk for userland.

Compile tests only.

branches: 1.30.10;
Retire OSI network stack. OK core@

branches: 1.29.8;

The rnd pseudo-device is not really optional, because it is in the same
source file as the entropy-pool code itself. Move it to std. This
will be cleaned up more when I split the sources up as they should be.

This fixes build breaks on several ports. Thanks to Havard Eidnes for
pointing them out.

branches: 1.28.2;
dependant -> dependent

Remove unused count (invariably "4") from pseudo-device fss.

branches: 1.26.18; 1.26.20;
Add options COMPAT_40 to files which have options COMPAT_30.

branches: 1.25.68; 1.25.70; 1.25.72; 1.25.74;
Remove 'count' argument for pseudo-devices that ignore it
(vnd, bpfilter, ppp, gif, gre, tun, sl, strip, faith, stf).

branches: 1.24.2; 1.24.4; 1.24.6;
Adjust comments for options FFS_NO_SNAPSHOT.

XXX: This option should be mentioned in options(4).

Enable ptyfs by default on the non-install and non small/tiny/ramdisk kernels

64 bit inode changes.

branches: 1.21.4;
Add COMPAT_20 (and COMPAT_16 in some cases) to kernel config files
that didn't have those options but had other earlier compat options.

Invert FFS_SNAPSHOT to FFS_NO_SNAPSHOT

Add file system snapshots to kernel configs.

- Ffs internal snapshots get compiled in unconditionally.

- File system snapshot device fss(4) added to all kernel configs that
have a disk. Device is commented out on all non-GENERIC kernels.

branches: 1.18.4; 1.18.6;
Add COMPAT_BSDPTY to the rest of the config files.

Add "options SYSCTL_INCLUDE_DESCR" to a lot of configs, but commented
out in most of them.

branches: 1.16.2;
add COMPAT_15/COMPAT_16

branches: 1.15.6;
enable USERCONF by default; it's small and extremely useful to have available.

Enable "pseudo-device clockctl" in all kernels, except
installation related kernels (INSTALL* and RAMDISK*).
This enables rc.conf(5) $ntpd_chroot to be used "out of the box"

branches: 1.13.2; 1.13.4;
Add the INCLUDE_CONFIG_FILE option to all config files. In config
files that are generic (ie, GENERIC, GENERICSBC, GENERIC32, ALL, or
ALPHA), it is uncommented.

Add commented-out USERCONF option. Mainly useful for install media
and can be optionally enabled based on miniroot and ramdisk size
requirements.

add options PIPE_SOCKETPAIR to individual kernel configs
the option is commented out on everything but kernels I was able
to recognize as INSTALL-like or ones for small memory machines

cleanup:
options SPACE TAB
makeoptions TAB
psuedo-device TAB
remove trailing whitespace
replace multiple spaces -> tabs
options "FOO" -> options FOO
options "FOO=bar" -> options FOO=bar
options "FOO=\"bar\"" -> options FOO="\"bar\""

memc attaches at mainbus now.

branches: 1.8.2;
Standardise TCP_COMPAT_42 as commented out, grouped with other COMPAT options,
and with the comment '4.2BSD TCP/IP bug compat. Not recommended'
Add commented out 'TCP_DEBUG # Record last TCP_NDEBUG packets with SO_DEBUG'
(All hail amiga and atari which make some attempt to automate the
multiplicity of config files...)

Enable DHCP and BOOTP as supported diskless NFS boot options.

Add rnd(4) pseudo-device.

Switch to the MI 53c710 driver recently committed by Izumi Tsutsui.

branches: 1.4.2;
Add "options COMPAT_AOUT_M68K".

Add the memory controller ASIC driver.

Add CD9660, plus some general cleanup.

branches: 1.1.2; 1.1.4;
Add preliminary support for the MVME162-LX 200/300 series of boards.

Currently, the major onboard devices are supported (disk, network,
rs232 and VMEbus). However, work is still need to support the remaining
devices (eg. IndustryPack sites).

These boards are available with a dazzling array of build options. At
this time, the following options are *required*:

o Real floating point hardware (the 68LC040 model isn't tested),
o The VMEchip2 must be present,
o If offboard VMEbus RAM is not present, at least 8MB of onboard
RAM is required.
o Even if offboard VMEbus RAM *is* present, at least 4MB of onboard
RAM is required. (Boards with 1 or 2MB onboard RAM *can* be
supported with offboard RAM, but not without some funky values in
the VMEbus Master mapping registers.)

There is no support for boards other than those in the -LX 200/300 series.
