remove "no options" for compat_ossaudio now it's disabled by default

branches: 1.40.8;
Make zaurus kernels use symbol tables loaded by the bootloader.

Now COPY_SYMTAB is no longer necessary and it saves ~500kbytes of
GENERIC, so re-enable options DDB (i.e. revert GENERIC rev 1.85).

Also fix zbsdmod.o (a kernel loader for Zaurus Linux) to load symbols
at a proper address as the MI sys/lib/libsa/loadfile_elf32.c does.

No particular comment on port-zaurus@:
https://mail-index.netbsd.org/port-zaurus/2019/11/11/msg000086.html

Note zbsdmod.c (derived from OpenBSD/zaurus) assumed that the loaded
kernels had "esym" variable at the top of its data section and
implicitly overwrote it with the address of loaded symbol tables.
OpenBSD/zaurus kernels used the esym value written by the zbsdmod.o
to initialize ksyms(4) on startup, but we will avoid such implicit
MD interface between the bootloader and kernels (though we don't
bother to add a symbol address value into bootinfo but just assume
symbols are loaded at end[] of a loaded kernel, as per the MI
libsa loadfile() implementation).

Worth to pullup to both netbsd-8 and netbsd-9.

Oops, revert previous.
Combinations between NICs and PHYs are unpredictable...

Fix kernel size overflow caused by addition of ure(4) and PHY drivers.

Modern USB NICs are useful due to availability in the market, although
they cannot exhibit full performance with ohci(4). Also, some of them
support RX/TX offloading, which can be useful even with ohci(4).

Therefore, rather add modern NICs in usbdevices.config.

Instead, remove PHY drivers that cannot be used with zaurus.

Now, all kernels fits within 5 MiB = 5120 KiB:
- GENERIC 5105K ( 15K free)
- C700 5098K ( 22K free)
- INSTALL 4991K (129K free)
- INSTALL_C700 4681K (439K free)

Revert changes that pinned-down i2c parent specs. The i2c subsystem
has been enhanced to make this unnecessary.

Fully specifiy the location of indirectly-configured I2C devices. In
particular, the parent spec must not be wild-carded, as doing so doesn't
work well on systems where more than one I2C bus is present.

branches: 1.35.2;
Shrink ramdisk to fit INSTALL kernel within 5MB:
- drop shutdown
- replace disklabel, fsck_ffs, and newfs with stripped-down versions

Disable compat stuffs that are accidentally accidentally added to rev 1.33.
Now INSTALL kernel fits within 5MB again.

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.

branches: 1.32.6;
Shrink the ramdisk of INSTALL kernel for zaurus in order to fit within 5MB.

Now free spaces of the main kernel and ramdisk are about 62KB and 215KB for
INSTALL, respectively.

OK christos

reduce install kernel size.

branches: 1.30.2;
wildcard speaker attachments, now that we can handle many of them.

Add a synthesized pc beeper and keyboard bell for platforms with an audio
device.

remove some phy(4) from zaurus INSTALL kernel.

avoid kernel size limit...

branches: 1.27.2;
Reduced INSTALL kernel size.

Backout previous, it does not work.

Provide a bit more space for the ram disk image

branches: 1.24.2;
Reorganize symbol table embedding. The existing option SYMTAB_SPACE is
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.

Add "no options COMPAT_70" to all kernel configuration files that
already had "no options COMPAT_60".

Adapt to increased ramdisk size

branches: 1.21.2;
Typo

disable more stuff.

branches: 1.19.2;
Bump the INSTALL ramdisk by 100k so that the contents fits again.
Approved by nonaka@

Add "no options COMPAT_60" to all kernel configuration files
that already had "no options COMPAT_50".

branches: 1.17.2;
Update all kernel configs mentioning WSEMUL_* but not already including
WSDISPLAY_COMPAT_USL using the following rules:
- If WSEMUL_ is commented out, add commented out out WSDISPLAY_COMPAT_USL
- If INSTALL or obviously memory constrained, add WSDISPLAY_DEFAULTSCREENS=1
and commented out WSDISPLAY_COMPAT_USL
- Otherwise add WSDISPLAY_COMPAT_USL

Some of the INSTALL configs for larger memory machines are probably suitable
for adding WSDISPLAY_COMPAT_USL.

Now wsconscfg(8) should be able to switch VTs when expected.

Implemented after no objection from tech-kern to the following:

Ensure all WSDISPLAY_COMPAT_USL entries have same comment

bump up ramdisk size.

P1003_1B_SEMAPHORE is no longer optional.

Try to shrink INSTALL kernel a bit.
Loading INSTALL kernel on SL-C1000 running Zaurus Linux still sometimes
fails (due to its size), but at least it works on maintenance kernel.

Reorganlization zlcd(4) and ztp(4) device attachments from nonaka@:
- ztp depends on zssp so attach ztp at zssp rather than pxaip
- split LCD backlight controls from zlcd(4) into new lcdctl device
to share it among forthcoming SL-C7x0 variants

Shrink ramdisk size to 2048KB.

Shrink INSTALL kerenl more:
- disable KERNFS (install ramdisk uses /sbin/dmesg directly)
- disable mice, audio, uk(4), and wsfont(4)

Reduce kernel size.
Tested on SL-C1000.

Fix PR/44898.

branches: 1.6.4; 1.6.6;
comment out KLOADER.

Added kloader support.

branches: 1.4.2;
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)
