1. Don't use the MSDOSFS code for accessing FreeBSD distribution data.
Use Robert Nordier's stand-alone DOS I/O library for the purpose.
It this works as well as Robert says it does, it should drastically reduce
(or even eliminate) our "I can't install from my DOS partition!" calls.
2. As a result of the above, go to stdio file descriptors for all
media types.
3. Taking advantage of #2, start using libftpio for FTP transfers instead
of maintaining our own parallel version of the FTP transfer code.
Yay! I ripped something out for a change!

makes MADV_SEQUENTIAL much more effective. I suggest that
we start using MADV_SEQUENTIAL on system utilities that mmap
their input files, and the I/O is predominantely sequential.
Below is a test with 'cmp' on two relatively large binary files,
where the files are so large that the caching is ineffective:
+ ls -l t1.xxx t2.xxx
-rw-r--r-- 1 root wheel 65598384 Dec 10 12:13 t1.xxx
-rw-r--r-- 1 root wheel 65598384 Dec 10 12:14 t2.xxx
+ time cmp t1.xxx t2.xxx

This change is as a result of an observation made by BDE.
has always held an open file descriptor. This allowed logging to
spare virtual consoles and being able to switch to them.
My previous change removed this since all writes were done with ttymsg()
which opens it's own fd, and hence syslogd didn't need it's own fd to
send messages on... but this caused an unexpected behavior change.
This should close PR#2176
in lots of unrelated junk from <net/if.h> and <net/if_ether.h>. These
functions still aren't prototyped anywhere (but should be in
<net/ethernet.h>---got that, Bill?).
do it themselves. (Some of these programs actually depended on this
beyond compiling the definition of struct ifinfo!) Also fix up some
other #include messes while we're at it.
Simplified average calculations. This also fixes potential overflow errors
and minor rounding inconsistencies (always round to nearest now).
Don't lose more SIGINFOs than necessary.
Print \r at the start of the status message. This clears the dots that
are sometimes left by ping -f.

dangerously dedicated. There is little error checking later, and
following garbage metadata outside the slice usually caused crashes,
Empty 'a' partitions are fairly easy to create by cloning the label
for the whole disk.

type to be int so that errors can be returned.
2) Use the new SIOCSIFMTU ether_ioctl support in the few drivers that are
using ether_ioctl().
3) In if_fxp.c: treat if_bpf as a token, not as a pointer. Don't bother
testing for FXP_NTXSEG being reached in fxp_start()...just check for
non-NULL 'm'. Change fxp_ioctl() to use ether_ioctl().
obvious effects are that most of the automagically chosen defaults
will now be displayed while going through the menu, and an improved
error handling thanks to the more detailed error status reporting.
2.2 fodder, but i'll leave it to Jordan's review.
sysinstall's new User&group menu will use it, hence it's a 2.2
candidate despite of providing new functionality.
