fragments in the file system by fragment (block) number. This new
mode does the necessary arithmetic to generate absolute fragment
numbers rather than than the cg-relative numbers printed in the default
mode.
If -f is passed once, contiguous fragment ranges are collapsed into
an X-Y format as free block lists are currently printed in regular
dumpfs output, but if specified twice, all block numbers are printed
individually, allowing both compact and more script-friendly
representation.
This proves quite handy when attempting to recover deleted data, as it
allows exclusion of non-deleted data from blocks searched.

o change ioctl's that pass channel lists in/out to handle variable-size
arrays instead of a fixed (compile-time) value; we do this in a way
that maintains binary compatibility
o change ifconfig so all channel list data structures are now allocated
to hold MAXCHAN entries (1536); this, for example, allows the kernel
to return > IEEE80211_CHAN_MAX entries for calls like IEEE80211_IOC_DEVCAPS
Usual moving of code with no changes from ipfw2.c to the
newly created files, and addition of prototypes to ipfw2.h
I have added forward declarations for ipfw_insn_* in ipfw2.h
to avoid a global dependency on ip_fw.h
In this episode:
- introduce a common header with a minimal set of common definitions;
- bring the main() function and options parser in main.c
- rename the main functions with an ipfw_ prefix
No code changes except for the introduction of a global variable,
resvd_set_number, which stores the RESVD_SET value from ip_fw.h
and is used to remove the dependency of main.c from ip_fw.h
(and the subtree of dependencies) for just a single constant.
program name, and ignore that entry. ipfw2.c code instead skips
this entry and starts with options at offset 0, relying on a more
tolerant implementation of the library.
This change fixes the issue by always passing a program name
in the first entry to getopt. The motivation for this change
is to remove a potential compatibility issue should we use
a different getopt() implementation in the future.
No functional changes.

There are still several signed/unsigned warnings left, which
require a bit more study for a proper fix.
This file has grown beyond reasonable limits.
We really need to split it into separate components (ipv4, ipv6,
dummynet, nat, table, userland-kernel communication ...) so we can
make mainteinance easier.

very well maintained and point user to sysutils/fusefs-ntfs, which
at the time of this writing seems to be a better alternative.

o correct typo that caused random channel selection
o explicitly add 1/2 and 1/4 width channels because channel lookups match
flags that include IEEE80211_CHANNEL_HALF and IEEE80211_CHANNEL_QUARTER
replace the table of partition with a simpler and faster array of strings.
The change in the array is done mechanically, using vi commands.
Most entries in the table are probably 15+ years old and largely outdated,
so the next step is to remove stale entries with more current values.

+ Remove a dead field of a struct. It serves no purpose anymore.
+ Remove a \n at the end of the format string of err(); the err()
function already adds a \n ;
+ remove many unnecessary casts which obfuscate the code.
This file has a huge number of indentation bugs, but I'd rather fix
them when/if we happen to modify the relevant parts of the code.

o add net80211 support for a tdma vap that is built on top of the
existing adhoc-demo support
o add tdma scheduling of frame transmission to the ath driver; it's
conceivable other devices might be capable of this too in which case
they can make use of the 802.11 protocol additions etc.
o add minor bits to user tools that need to know: ifconfig to setup and
configure, new statistics in athstats, and new debug mask bits
While the architecture can support >2 slots in a TDMA BSS the current
design is intended (and tested) for only 2 slots.
