shared code and converting all ufs references. Originally it may
have made sense to share common features between the two filesystems,
but recently it has only caused problems, the UFS2 work being the
final straw.
All UFS_* indirect calls are now direct calls to ext2_* functions,
and ext2fs-specific mount and inode structures have been introduced.
struct _scrmap, so that it doesn't break C++ programs (name of element of
the structure is the same as the name of the scructure itself).

the former blocks software interrupts, while the latter blocks
hardware interrupts.
Avoid one place where I'm at splnet across a call to copyout. Leave
one in place to give bde something to complain about :-). Actaully,
I'll fix it in a subsequent commit.

allow recovery from transmission lockups which occur in the middle
of the descriptor list, rather than just at the beginning.
For some unknown reason, Rhine II chips have a tendency to stop
transmitting while under heavy load, possibly due to collisions.
Whether this behavior is due to a hardware bug or a driver glitch
is unknown as of now.
In either case, this change allows the driver to gracefully recover
from such situations.
Special thanks go to The Anarcat <anarcat@anarcat.dyndns.org>, who
bugged me into looking at this and to
Dominic Marks <dominic_marks@btinternet.com>, who performed a great
deal of testing to help characterize this problem.

inter-process signalling ceased to preserve and return that value,
instead always returning EPERM. This meant that it was possible
to "probe" the pid space for processes that were not otherwise
visible. This change reverts that reversion.

previously used "micro-optimization" (count-down loop) into a
pessimization. Now the loops are written in the more natural count-up
form.
Also, while being there, i made the logic in out_fdc() similar to the
logic in in_fdc(). The old implementation was a bit bogus anyway
since it first tested the DIO bit and only afterwards the RQM bit.
However, according to the description of the i82077, the DIO bit is
only guaranteed to be valid once the RQM bit is set. Thus, the old
implementatoin would have had the chance to misbehave on a controller
that is implemented in accordance with the i82077 description (but is
not bug-for-bug compatible).

results in the syncache entry being turned into a socket. While it's
not used in the main tree, this is required in the MAC tree so that
labels can be propagated from the mbuf to the socket. This is also
useful if you're doing things like transparent IP connection hijacking
and you want to use the syncache/cookie mechanism, but we won't go
there.

structures etc. to ext2fs-specific names, and remove ufs-specific
code that is no longer required. As a first stage, the code will
still convert back and forth between the on-disk format and struct
inode, so the struct dinode fields have been added to struct inode
for now.
Note that these files are not yet connected to the build.
additional system boot ordering entry, SI_SUB_MAC_LATE, which occurs

with 16-bit ints, since u_short is promoted when it is passed to a
varargs function. gcc now warns about this. We always pass small
integers (this is well obuscated), so there are no conversion problems.
Fixed a related style bug (bogus cast).
-current, since offsetof() is defined a header under /sys so that
system sources don't need to have this wrong include.
This bug was only detected because my version of <stddef.h> has some
spelling fixes (s/field/member/g) and gcc is now sensitive to the spelling
of arg names in macros as required by standards (ISO C90 6.8.3...).
Get rid of the INTERNALSTATICLIB knob and just use plain INTERNALLIB.
INTERNALLIB now means to build static library only and don't install
anything. Added a NOINSTALLLIB knob for libpam/modules. To not
build any library at all, just do not set LIB.
Ipfw processing of frames at layer 2 can be enabled by the sysctl variable
net.link.ether.ipfw=1
Consider this feature experimental, because right now, the firewall
is invoked in the places indicated below, and controlled by the
sysctl variables listed on the right. As a consequence, a packet
can be filtered from 1 to 4 times depending on the path it follows,
which might make a ruleset a bit hard to follow.
I will add an ipfw option to tell if we want a given rule to apply
to ether_demux() and ether_output_frame(), but we have run out of
flags in the struct ip_fw so i need to think a bit on how to implement
this.
