Reapply rev 1.37 (hide the __attribute__ gcc keyword) into RELENG_4 even
though it was backed out.
With out this change the TenDRA compiler is not bootstrapable.
style(9) cleanups mostly consisting of:
o explicitly check return values and variables against a value
o return x; -> return (x);
o fix inconsistent sysexits usage by nuking it (partially
suggested by bde)
o Expand the explaination of the -b option WRT the resulting
group ACL entry in relation to the existing group and mask
ACL entries.
o Move the explanation of multiple ACL entries on the command
line to the ACL ENTRIES section.

o Remove KSE race in setuid() in which oldcred was preserved before giant
was grabbed. This was introduced in 1.101 when the giant pushdown
for kern_prot.c was originally performed.

o General style, formatting, etc, improvements:
- uid's -> uids
- whitespace improvements, linewrap improvements
- reorder copyright more appropriately
- remove redundant MP SAFE comments, add one "NOT MPSAFE?"
for setgroups(), which seems to be the sole un-changed system
call in the file.
- clean up securelevel_g?() functions, improve comments.

Fix a bug with transmitter restart after receiving a 0 window. The
receiver was not sending an immediate ack with delayed acks turned on
when the input buffer is drained, preventing the transmitter from
restarting immediately.
Propogate the TCP_NODELAY option to accept()ed sockets. (Helps tbench and
is a good idea anyway).
Some cleanup. Identify additonal issues in comments.
Forget to remove fsck from src/release/{alpha,pc98}/boot_crunch.conf,
which should be done with src/release/i386/boot_crunch.conf rev 1.51
and src/usr.sbin/sysinstall/install.c rev 1.311.
Sysinstall cleanups for installation:
1) Use devfs to mount filesystems. If mounting devfs is fail,
fallback to old code.
2) When fscking filesystems, use 'fsck_ffs' explicitly. As a
result, we no longer need 'fsck' the wrapper program.

Add functionality and fix bugs so the driver will work with soon-to-be
released management apps.
1. Implement poll(). This will check for queued aif's so that a
subsequent ioctl call to retrieve the next aif will not block.
2. Don't catch signals when sleeping on a fib sent from userland. This
causes a race and panic due to the pthread context switcher waking
up the tsleep at inopportune times.
3. Fix some whitespace nits.

Work around world breakage in previous commit. The bug is in
<security/pam_misc.h>. It declares a function parameter named 'send',
so nothing that includes both <unistd.h> (which declares send(2)) and
<security/pam_misc.h> be compiled with WARNS=2 unless NO_WERRROR is
set.
Remove kget() feature, which is removed from 5-current kernel.
Since userconfig feature is implemented by tweaking variables (hint.*)
with loader(8), we can put back an equivalent feature. Maybe the first
step for this is to commit yokota-san's patch (add userconfig command
for loader).

o Stop abusing MD headers with non-MD types.
o Hide nonstandard functions and types in <netinet/in.h> when
_POSIX_SOURCE is defined.
o Add some missing types (required by POSIX.1-200x) to <netinet/in.h>.
o Restore vendor ID from Rev 1.1 in <netinet/in.h> and make use of new
__FBSDID() macro.
o Fix some miscellaneous issues in <arpa/inet.h>.
o Correct final argument for the inet_ntop() function (POSIX.1-200x).
o Get rid of the namespace pollution from <sys/types.h> in
<arpa/inet.h>.

vm/vm_kern.c: rate limit (to once per second) diagnostic printf when
you run out of mbuf address space.
kern/subr_mbuf.c: print a warning message when mb_alloc fails, again
rate-limited to at most once per second. This covers other
cases of mbuf allocation failures. Probably it also overlaps the
one handled in vm/vm_kern.c, so maybe the latter should go away.
This warning will let us gradually remove the printf that are scattered
across most network drivers to report mbuf allocation failures.
Those are potentially dangerous, in that they are not rate-limited and
can easily cause systems to panic.
Unless there is disagreement (which does not seem to be the case
judging from the discussion on -net so far), and because this is
sort of a safety bugfix, I plan to commit a similar change to STABLE
during the weekend (it affects kern/uipc_mbuf.c there).
