Since locale reading code not resistent against stack overflowing or
similar intruder attacks, don't allow PATH_LOCALE env variable action

strdup() it to prevent unsetenv() or setenv() effects. Check its length to
not allow user to overflow internal locale buffer. Move PATH_LOCALE

POSIX: make better stub for LC_MONETARY & LC_NUMERIC, now it check
locale directory existance instead of refusing all non-C non-POSIX
locales. POSIX treats empty locale env variable as unset variable
while our old code treats it as "C" locale, fix it. Implement previous locale
restoring, if locale setting fails. Old code assumes success if some
of LC_ALL subset is successed even other fails, POSIX treats it as
failure with previous locale restoring, fix it.

FTP error return code because
1) They return NULL, it means that ftpErrno can't be used because
it takes file pointer
2) They don't have FILE-type argument as f.e. ftpGet/ftpPut to use
it for ftpErrno instead.
For that functions I add yet one int* type argument to store
FTP error return code. It is impossible to add some global variable
for that reason, because user can have multiply FTP connections
opened at the same time.
So, interface changed, major number bumped.
Userland changes will follows.
Minor bugfixes, the code:
Forget to close file in few places, when failure occurse
Forget to NULL cached host name, multiply free is possible
When malloc fails. don't try to memset NULL pointer, it cause core dump
Replace malloc+memset with calloc, theoretically it can do some
optimization of zeroing process internally
Improve error diagnostic
dealing w/the fixit floppy.

dead kernel debugging. The previous code was a "do nothing".
The most obvious side effect of this is that you can now do things like
this and reasonably expect them to work:
dmesg -M /var/crash/vmcore.3 -N /var/crash/kernel.3
ps -axl -M /var/crash/vmcore.3 -N /var/crash/kernel.3
A good deal of this was lifted from the gdb code to do this, as well as
from NetBSD's libkvm (which has completely different VM macros)
and forwards compatable with version 3. This is needed to enable storing
a run-time library path in the dynamic linking headers. The crt startup
tries version 4 first, and falls back to version 3, so an executable that
is linked on -current will work with the ld.so on 2.1.x and less.

As has been pointed out to me (quite a few times) in email, the people

about updating /etc/rc.
Bruce also pointed out that after my last commit, it was no longer

a bit.

ncurses has int and actually sets the return value. This problem has

Here are the diffs for libc_r to get it one step closer to P1003.1c
These make most of the thread/mutex/condvar structures opaque to the
user. There are three functions which have been renamed with _np
suffixes because they are extensions to P1003.1c (I did them for JAVA,
which needs to suspend/resume threads and also start threads suspended).
I've created a new header (pthread_np.h) for the non-POSIX stuff.
The egrep tags stuff in /usr/src/lib/libc_r/Makefile that I uncommented

tags anyway, 'cause most of the source is in libc which does have tags.

I should have sent this diff with the pthread(3) man page.
It allows people to type

also:
The diff attached adds a pthread(3) man page to /usr/src/share/man/man3.
The idea is that without libc_r installed, this man page will give people
enough info to know that they have to build libc_r.

directly in order to obtain binding information, check that the local
ypbind is using a reserved port and return YPERR_YPBIND if it isn't.
We should not trust any ypbind running on a port >= IPPORT_RESERVED;
it may have been started by a malicious user hoping to trick us into
talking to a bogus ypserv.
Note that we do not check the ypserv port returned to us from ypbind.
It is assumed that ypbind has already done a reserved port test (or not,
depending on whether or not it was started with -s); if we trust the
authenticity of the local ypbind, we should also trust its judgement.
