bump ramdisk sizes to cope with GCC 7 bloat.

Remove TCP_COMPAT_42 from the config files. Pass 1.

Remove unused count from pseudo-device md.

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

branches: 1.38.4; 1.38.6;
Changes to MEMORY_RBFLAGS option:
- renamed to MEMORY_DISK_RBFLAGS to better fit the rest of the
MEMORY_DISK options(4)
- change default value to RB_AUTOBOOT instead of RB_SINGLE, and adapt
the config(5) files accordingly
- document this option inside options(4)

Bump ramdisk size from 500k to 600k to compensate for recent bloat,
probably caused by ifconfig now needing proplib.

Always specify COPTS="-Os" and disable several options and devices
to shrink kernels. Current sun68k bootloader can't load a kernel larger
than ~2MB, and our ever growing kernel have been reached the limit.

branches: 1.35.16;
Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

branches: 1.34.6;

Adjust comments for options FFS_NO_SNAPSHOT.

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

typo in comment. (since 1994?!)

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

revert "defflag VMSWAP" changes for now.
there seems to be far more people who don't want to edit
their kernel config files than i thought.

add "options VMSWAP" to non INSTALL kernels.

branches: 1.27.6;
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.

Enable disconnect/reselect for esp(4) on 3/80 by default.

It also implies to enable tagged queueing, which works fine on my 3/80:

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

branches: 1.23.2;
commands have grown, make the ramdisk bigger.

branches: 1.22.6;
enable USERCONF by default; it's small and extremely useful to have available.

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.

Rename MEMORY_DISK_SIZE (formerly MINIROOTSIZE) to MEMORY_DISK_ROOT_SIZE,
which was suggested by Izumi Tsutsui <tsutsui@ceres.dti.ne.jp> as
being more consistent with what it's controlling...

* rename MINIROOTSIZE to MEMORY_DISK_SIZE, so that all md(4) options
are now consistently named
* fold opt_mdsize.h into opt_md.h

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\""

Standardise TCP_COMPAT_42 as commented out, grouped with other COMPAT options,

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...)

Fix various misspellings of compatible/compatibility.

We cannot specify root on md0a because md is pseudo-device.
"options MEMORY_DISK_IS_ROOT" is enough for this.

- Sync MINIROOTSIZE with etc/disktab.
- Remove ppp. (ramdisk does not have pppd, anyway)

Config root on md0a, not md0.

Sync with RAMDISK:
No need for any COMPAT_* options in the ramdisk kernel
Can do without the uk driver also...

Like INSTALL and INSTALL3X, leave out DDB.
(Can patch using the PROM if needed.)

Move the sun3-vs-sun3x stuff into std.sun3 and std.sun3x
