Close the ip-fragment hole.
Waste less memory.
Rewrite to contemporary more readable style.
Kill separate IPACCT facility, use "accept" rules in IPFIREWALL.

- Optimise the linux a.out loading and uselib system calls so they
take advantage of some of John's recent interface improvements.
Basically, this means they make far less map changes than before.
- Attempt to plug some potentially nasty kernel_map memory leaks..
- Improve support for QMAGIC libs (I only use QMAGIC (ie: a.out libraries from
the slackware 3.0 dist) but this depends on other changes to enhance
the /compat/linux support)
- uselib goes out through a single exit as part of the resource tracking
that I did when closing the resource leaks on errors. This could be
cleaner than what I did, but making a 30-deep nested if/else was not my
idea of fun, neither did I want to repeat the same code 30 times over for
each failure possibility. I guess this function needs to be split into
smaller functions to solve this.
I've been running the Linux Netscape-2.0 (with Java) to test this, and apart
from the long-standing problem with the missing scrollbars, it appears to
still work as before with ZMAGIC libs (and the leaks).. However, I've
been using it with mods for the signal trampoline code for native linux stack
frames on signals and exterminated the blasted sigreturn printf() problem,
so I can't be certain that there is not a dependency on something else.
- Clean up the access to our ifnet structure by caching a pointer

Create devfs entries in dsopen() and (unsuccessfully) attempt to make

fd and wt drivers need bounce buffers, so this normally saves 32K-1K
of kernel memory.
Keep track of which DMA channels are busy. isa_dmadone() must now be
called when DMA has finished or been aborted.
Panic for unallocated and too-small (required) bounce buffers.
fd.c:
There will be new warnings about isa_dmadone() not being called after
DMA has been aborted.
sound/dmabuf.c:
isa_dmadone() needs more parameters than are available, so temporarily
use a new interface isa_dmadone_nobounce() to avoid having to worry
about panics for fake parameters. Untested.

Fixed the (unused) values returned from device attach functions.
Fixed checking of unit number in device open functions - don't load bad
pointers or print error messages about the contents of bad pointers.
Removed unused #includes.
asc.c:
Fixed premature setting of flags in ascopen() - copied the better order
in gscopen().
gsc.c:
Fixed conflict handling for drq:
- fail the probe if the configured drq doesn't match the actual drq.
- set the configured drq to match the actual drq in the autoconfig case.

Speed up for vfs_bio -- addition of a routine bqrelse to greatly diminish

Correct the ordering for vrele of .text and release of credentials.
Use the selective tlb update for 486/586/P6.
Numerous fixes to the size of objects allocated for files. Additionally,
fixes in the various pagers.
Fixes for proper positioning of vnode_pager_setsize in msdosfs and ext2fs.
Fixes in the swap pager for exhausted resources. The pageout code
will not as readily thrash.
Change the page queue flags (PG_ACTIVE, PG_INACTIVE, PG_FREE, PG_CACHE) into
page queue indices (PQ_ACTIVE, PQ_INACTIVE, PQ_FREE, PQ_CACHE),
thereby improving efficiency of several routines.
Eliminate even more unnecessary vm_page_protect operations.
Significantly speed up process forks.
Make vm_object_page_clean more efficient, thereby eliminating the pause
that happens every 30seconds.
Make sequential clustered writes B_ASYNC instead of B_DELWRI even in the
case of filesystems mounted async.
Fix a panic with busy pages when write clustering is done for non-VMIO
buffers.
Save 112K for SB, 64K for PAS and 64K for MSS.
Since PAS use SB emulation, 176K normally saved for it.
Few minor optimizations added like in Linux driver.
When you start tracker and produce some heavy disk activity,
output interrupts becomes lost and I don't know how to solve it
finally. Newly added code at least allows recovery after timeout.
2) Use CURSIG(curproc) in PROCESS_ABORTING instead of junk code was there.
3) Reanimate timeout code in DO_SLEEP by setting WK_TIMEOUT flag
which is never set in old code.
4) DO_SLEEP: set aborting flag on interrupting singnals as supposed, not
on signals which do nothing as in old code.
5) Cleanup WAKE_UP macro, WK_WAKEUP not used.
6) Remove wrong typecasts in sleep/wakeup code.
This random address can be matched (with some probability) with another
sleep addresses from other drivers, which can cause strange sleep/wakeup
sequence. Rewrite this ugly code to do the right thing.
Add more features to the one remaining to handle the job:
