f1d896d117 Make a couple of the stat flags dependent on the sys/stat.h header file
that this source is compiled against. This source is referenced by
install which is needed as a build tool and must be able to compile
against NetBSD headers and libraries if we have a hope of supporting
another architecture.

With this change, that's two working programs down and 3945 (?) to go.
The other one was make, but that didn't need any changes to work under
FreeBSD/Alpha. 8-)

8c6d2f42e1 1. EOF was returned when the buffer size was larger than INT_MAX. This
case has very little to do with the output size being larger than
   INT_MAX.
2. The new #include of <limits.h> was disordered.
3. The new declaration of `on' was disordered (integer types go together).
4. Testing an unsigned value for > 0 was fishy.

Alexander Langer
7167d5b04c Convert caddr_t --> void * for sys/mman.h functions.
mlock, mmap, mprotect, msync, munlock, and munmap are defined by
POSIX as taking void *.  The const modifier has been added to
mlock, munlock, and mprotect as the standard dictates.

minherit comes from OpenBSD and has been updated to conform with
their recent change to void *.

madvise and mincore are not defined by POSIX, but their arguments
have been modified to be consistent with the POSIX-defined functions.
mincore takes a const pointer, but madvise does not due to the
MADV_FREE case.

6e690ad4ca Return back to BSD snprintf semantics which recent C9x standard adopts
instead of Singe Unix, thanx Bruce for explaining, I am not realize
standards war was there.

But now, fix n == 0 case to not return error and fix check for too
big n.

Things left to do: check for overflow in arguments.

e0b123f6d0 1) Oops! Insert again if (n == 0) return 0.
Final word is Bruce's quote:

C9x specifies the BSD4.4-Lite behaviour:

       [#3] ...   Thus,  the
       null-terminated  output  has  been completely written if and
       only if the returned value is less than n.

It means that if we not have any null-terminated output as for n == 0
we can't return value less than n, so we forced to return value
equal to n i.e. 0

The next good thing is glibc compatibility, of course.

2) Do check for too big n in machine-independent way.
3) Minor optimization assuming EOF is < 0

5ebfa8de69 Back out part related to "return 0 if n == 0" and return EOF as before.
The main argument is that it is impossible to determine if %n evaluated or not
when snprintf return 0, because it can happens for both n == 0 and n == 1.
Although EOF here is good indication of the end of process, if n is
decreased in the loop...
Since it is already supposed in many places that EOF *is* negative, f.e.
from Single Unix specs for snprintf
"return ... a negative value if an output error was encountered"
this not makes situation worse.

a65a537cb1 Remove wrong comment about snprintf:
"return the number of bytes needed, rather the number used"

4ecaf22055 snprintf return value fixes to conform Single Unix specs:
1) if buffer size is smaller than arguments size, return buffer
size, not arguments size as before.

2) if buffer size is 0, return 0, not EOF as before.
(now it is compatible with Linux and Apache implementations too).

NOTE: Single Unix specs says:

If the value of n {buffer size} is zero on a call to snprintf(), an
unspecified value less than 1 is returned.

It means we can't return EOF since EOF can take *any* value in general
not especially < 1. Better variant will be return -1 (it is less then
1 and different with n == 1 case) but -1 value is already occuped by
EOF in our implementation, so we can't distinguish true IO error
in that case. So 0 here is only possible case still conforming
to Single Unix specs.

d5bc59bb81 Fix recursion problem which occurs when a signal is received during
a malloc. The signal handler creates a thread which requires a malloc...
For now, the only thing to do is to block signals. When we move user
pthreads to use the kernel threads, mutexes will be implemented in kernel
space and then malloc can revert.

8fddd06099 Fixed long double formats. They were mostly not implemented except
on systems where long doubles are just doubles.  FreeBSD hasn't
been such a system since it started using gcc-2.5 many years ago.
The fix is of low quality.  It loses precision.

scanf() of long doubles doesn't seem to be used much, but gdb-4.16
uses %Lg format in its expression parser if it thinks that the
system supports printf'ing of long doubles.  The symptom was that
floating point literals were usually interpreted to be 0.0.

Add an option to the way UFS works dependent on the SUID bit of directories
This changes makes things a whole lot simpler on systems running as
fileservers for PCs and MACS. to enable the new code you must
1/ enable option SUIDDIR on the kernel.
2/ mount the filesystem with option suiddir.
hopefully this makes it difficult enough for people to
do this accidentally.
see the new chmod(2) man page for detailed info.

b1f4a44b03 Reviewed by: various.
Ever since I first say the way the mount flags were used I've hated the
fact that modes, and events, internal and exported, and short-term
and long term flags are all thrown together. Finally it's annoyed me enough..
This patch to the entire FreeBSD tree adds a second mount flag word
to the mount struct. it is not exported to userspace. I have moved
some of the non exported flags over to this word. this means that we now
have 8 free bits in the mount flags. There are another two that might
well move over, but which I'm not sure about.
The only user visible change would have been in pstat -v, except
that davidg has disabled it anyhow.
I'd still like to move the state flags and the 'command' flags
apart from each other.. e.g. MNT_FORCE really doesn't have the
same semantics as MNT_RDONLY, but that's left  for another day.
