Some cosmetic tweaks.
Some improvement in translation.
This change, together with recent change to jmembers.sgml and jcontrib.sgml,
should definitely go into 2.2.
This includes the following changes:
- Support for poking ARP entries into the local table is now built
in, so the arptab.c module I hacked together is no longer needed.
- rarp_process() and rarp_reply() now accept a len argument which is
passed down from rarp_loop() which tells rarp_reply() exactly how
long the original RARP frame was. (Usually, it's 60 bytes, which is
the minimum.) Previously, the length was calculated using the sum
of sizeof(struct ether_header) + sizeof(struct ether_arp) (plus the
ethernet frame header, I think). The result was a total packet
length of 42 bytes. Now, rarp_reply() sends out packets that are
the same size as those it recieves (60 bytes). This agrees with the
behavior of rarpd on SunOS (as observed with tcpdump). The unused
extra bytes are zeroed.
the races in my previous commits here, and fix some other problems with
syslogd as well.
- if the child process exited early (eg: could not bind to the socket),
the boot process would hang for 30 seconds. The parent was not noticing
that the child had exited. (my fault)
- when writing to tty devices, instead of treating them like files that
need \r\n instead of \n, actually use ttymsg() which has specific code
intended to write to potentially blocking ttys safely. I had a machine
lock up last night because /dev/console on a serial port got flow control
blocked. Setting comcontrol drainwait fixed everything but syslogd which
was going into a spin trying to write to the console and completely
ignoreing everything else.
- fix a couple of nonsensical bits of code while here.. eg: wait3 takes
a pointer to an int. There is no sense in declaring it as 'union wait',
then casting the pointer to (int *), then forgetting about it.
Garbage in `eacces' caused the wrong errno to be set for non-EACCES errors.
Garbage in `etxtbsy' caused a semi-random retry strategy for ETXTBSY errors.
Found by: NIST-PCTS. gcc -Wall reported the problem, but -Wall is not
enabled for libc.
substantially increasing buffer space. Specifically, we double
the number of buffers, but allocate only half the amount of memory
per buffer. Note that VDIR files aren't cached unless instantiated
in a buffer. This will significantly improve caching.
We've already got it in libc, but both libraries are incompatible
wrt. their header files and internal data structures. This
incompatibility caused the expr(1) on the fixit floppy to mysteriously
dump core for the colon operator.
Strong 2.2 candidate, since it fixes the usage of MAKEDEV on the fixit
floppy. I'd like to get it reviewed by somebody else though.

Add printing of PCI header type register. (This makes the output
80 columns wide. Ughh. I'm looking for a better way to put the
information on one line ...)
