included. It was used for general files. This caused the __depend_*
lists in <bsd.dep.mk> to be empty, so mkdep was never run, so
.depend never existed, so it was always out of date, so `rm -f
.depend' was always executed to update it.

Doubled the number of transmit descriptors to 128 so that the internal
FIFO in the NIC can be fully filled when dealing with small packets.
Several minor performance improvements.

Add -s flag to tftpd. This enables the so-called secure mode
of tftpd where it chroots to a given directory before allowing access
to the files. In addition, it runs as nobody when in this mode.

- don't include <sys/ioctl.h> in any header. Include <sys/ioccom.h>
instead. This was already done in 4.4Lite for the most important
ioctl headers. Header spam currently increases kernel build
times by 10-20%. There are more than 30000 #includes (not counting
duplicates) for compiling LINT.
- include <sys/types.h> if and only it is necessary to make the header
almost self-sufficient (some ioctl headers still need structs from
elsewhere).
- uniformized idempotency ifdefs. Copied the style in the 4.4Lite
ioctl headers.
Fixed the following bugs:
- the buffer was reprinted endlessly when msg.bufx == 0 and (for a
different reason) when msg.bufx == 1.
- the last byte of the buffer wasn't printed except in the the infinite
loop cases.
- the comment about walking the buffer didn't match the (correct) code.
- minor -Wall and style bugs.
Not fixed:
- excessive newline processing which hid the non-printing of the last
byte of the buffer.
drop the oldest entry in the queue.
There was a fair bit of discussion as to whether or not the
proper action is to drop a random entry in the queue. It's
my conclusion that a random drop is better than a head drop,
however profiling this section of code (done by John Capo)
shows that a head-drop results in a significant performance
increase.
There are scenarios where a random drop is more appropriate.
If I find one in reality, I'll add the random drop code under
a conditional.

It is needed for implementation details but very little of it is
needed for the interface. Include it in the few places that didn't
already include it.

Put the jump table for i486_bzero() in the data section. This

comma expression has no effect" in the MAKE_SET() macro. This also
fixes compiling with -O3 (which removes static functions unless
there is a suitable reference to them). Declaring all the static
symbols as __unused would also fix the warning, but would be bogus
(they are used) and wouldn't fix -O3. However, the dummy pointers
for the references waste about 1.5K text and 20K symbol space for
GENERIC. This wastage hasn't changed - the dummy pointers are just
nonzero now.
