Bring in the WARNS directive from NetBSD, localized in a new bsd.sys.mk
to avoid polluting sys.mk. This directive controls the addition of
compiler warning flags to CFLAGS in a relatively compiler-neutral manner.
The idea is that WARNS can be set in Makefile.inc or in individual
Makefiles as they become clean, to prevent the introduction of new
warnings in the code (-Werror is added by default when WARNS > 0).
This behaviour can be overridden with the following two knobs:
NO_WARNS disables the checking of WARNS completely
NO_WERROR disables the addition of -Werror to the flags.
Additionally, setting WFORMAT to 1 (in makefiles) and/or defining
FORMAT_AUDIT (by the user) will enable increased checking of format
string arguments.

The idea is that WARNS can be set in Makefile.inc or in individual
Makefiles as they become clean, to prevent the introduction of new
warnings in the code. -Werror is added by default
machines. The code formerly read:
long val;
if (val < (long)-0x80000000 || ...)
return EINVAL;
The constant 0x80000000 has type unsigned int. The unary `-'
operator does not change the type (or the value, in this case).
Therefore the promotion to long is done by 0-extension, giving
0x0000000080000000 instead of the desired 0xffffffff80000000. I
got rid of the `-' and changed the cast to (int32_t) to give proper
sign-extension on all architectures and to better reflect the fact
that we are range-checking a 32-bit value.
This commit also makes the analogous changes to ng_int{8,16}_parse
for consistency.

committed to disk before clearing them. More specifically, when
free_newdirblk is called, we know that the inode claims the new
directory block. However, if the associated pagedep is still linked
onto the directory buffer dependency chain, then some of the entries
on the pd_pendinghd list may not be committed to disk yet. In this
case, we will simply note that the inode claims the block and let
the pd_pendinghd list be processed when the pagedep is next written.
If the pagedep is no longer on the buffer dependency chain, then
all the entries on the pd_pending list are committed to disk and
we can free them in free_newdirblk. This corrects a window of
vulnerability introduced in the code added in version 1.95.

DF step 3.3V functionality.

82C146. The Intel i82365SL-DF supports 3.3V cards. The Step A/B/C
parts do not appear to support this. This is hard to know for sure
since it was deduced from "compatible" parts' data sheets and the
article mentioned below.
Rework the VLSI detection to be a little nicer and not depend on
scanning cards twice. This would allow bad VLSI cards to coexist with
a good intel card, for example. We now detect i82365SL-DF cards where
before we'd detect a VLSI. For the most part, this is good, but we
run a small chance of detecting a single slot 82C146 as a i82365SL-DF.
Since I can't find a datasheet for the 82c146, I don't know if this is
a problem or not.
This work is based on an excellent article, in Japanese, by NAKAGAWA,
Yoshihisa-san that appeared in FreeBSD Press Number 4. He provided a
patch against PAO3 in his article. Since the pcic.c code has changed
some since then, I've gone ahead and cleaned up his patch somewhat and
changed how the code detects the buggy '146 cards.
I also removed the comment asking if there were other cards that
matched the 82C146 since we found one and additional information isn't
necessary.
vm_mtx does not recurse and is required for most low level
vm operations.
faults can not be taken without holding Giant.
Memory subsystems can now call the base page allocators safely.
Almost all atomic ops were removed as they are covered under the
vm mutex.
Alpha and ia64 now need to catch up to i386's trap handlers.
FFS and NFS have been tested, other filesystems will need minor
changes (grabbing the vm lock when twiddling page properties).

For now, fix this by not saving the source address of the reply; this

substring operations and allowing the putback buffer size to be the limiting
factor. If the putback buffer size if reached, m4 gives an error instead of
silently truncating the string.
