Fix outdated or misleading comments for MEMORY_DISK_ROOT_SIZE.

G/C "MAPPECOPY". It is the deadest of wood, and never actually worked in
NetBSD.

Remove compat_svr4 and compat_svr4_32, as discussed on tech-kern@ recently,
but also as discussed several times in the past.

Unreference IPF/PF from all the config files, and enable NPF instead when
wanted. This also fixes some inconsistencies I saw in several files (eg
IPF options while IPF was not compiled, IPF+PF enabled by default, etc).

branches: 1.115.2; 1.115.4;
Nuke DIRECTED_BROADCAST, it is not documented and not enabled anywhere. It
probably wouldn't have built correctly anyway, since there is no associated
defflag.

These ten lines of code in ip_input.c already look a lot better.

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.

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.

Increase the image size to 1700KB.
At this point, the build succeeds if the build path is short,
but may fail if long. Thanks for martin@ and tsutsui@.

Finally switch PSX16550 fast serial board driver to using MI com(4) driver.
Based on isaki@'s patch and debugged by both isaki@ and tsutsui@.

PSX16550 specific hardware infomation is taken from Human68k's PSXIO driver:
http://retropc.net/x68000/software/hardware/psx16550/

XXX1: TL16C550C seems to have some timing critical issue around THRE interrupt
XXX2: auto hardware flow control of TL16C550 is not implemented in MI com(4)

WABPL is no longer considered experimental (has not been for some time)
so update its comment in config files.

branches: 1.93.2;

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.

Obsolete pow(4) and rtcalarm(8). Discussed in port-x68k@.
Probably the combination of pow(4) ioctl and rtcalarm(8) does
not work for a long time, and nobody uses them.
I'll rewrite a part about power switch handler as a new device.

branches: 1.91.4;
merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

See http://mail-index.netbsd.org/tech-kern/2011/02/19/msg010025.html

Remove unused count from pseudo-device md.

enable IPFILTER_COMPAT in all kernels that have ipfilter already.
canonicalise several of the ipf option segments in various files
(this mostly means adding commented out IPFILTER_DEFAULT_BLOCK,
or adding commented or uncommented IPFILTER_LOG or IPFILTER_LOOKUP
option statements.)

i built about 20 of these kernels to check, but not all of them.

branches: 1.88.2; 1.88.4;
Remove the portalfs kernel file system driver. Replace mount_portal(8)
with a version based on puffs. User functionality remains the same.

Remove SHMMAXPGS from all kernel configs. Dynamically compute the
initial limit as 1/4 of the physical memory. Ensure the limit is at
least 1024 pages, the old default on most platforms.

branches: 1.86.2;
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)

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

Ensure all INSTALL config files consistantly include PIPE_SOCKETPAIR,
MALLOC_NOINLINE, and VNODE_OP_NOINLINE. The exceptions are when they
include another config files that already defines the options, or if
they are for an embedded board, just define a few extra options, and
do not already define PIPE_SOCKETPAIR.

Adjust the ramdisk size.

Ensure all INSTALL* kernels have two ptys, and a note explaining why:
pseudo-device pty 2 # pseudo-terminals (Sysinst needs two)
(Some installers may not be using sysinst, in which case this just reduces
the number of ptys from 16 that are not used to 2 that are not used)
For i386 conf files, no change other than comments.

Use "options<SPACE><TAB>" not "options<TAB>" - noted by simonb.
Move VNODE_OP_NOINLINE and NFS_V2_ONLY into '# Filesystem options' section.
Consistently label '# Filesystem options' and '#File systems' sections.

Ensure all INSTALL config files have (at least) COPTS="-Os", cincluding bebox
based on it working already for macppc.
Also add commented out:
#options VNODE_OP_NOINLINE # Don't inline vnode op calls
#options NFS_V2_ONLY # Exclude NFS3 and NQNFS code
