convenient when the source string isn't null-terminated.
Implement the other conversion functions (mbstowcs(), mbsrtowcs(), wcstombs(),
wcsrtombs()) in terms of these new functions.
the thread ID and call db_trace_thread().
Since arm has all the logic in db_stack_trace_cmd(), rename the
new DB_COMMAND function to db_stack_trace to avoid conflicts on
arm.
While here, have db_stack_trace parse its own arguments so that
we can use a more natural radix for IDs. If the ID is not a thread
ID, or more precisely when no thread exists with the ID, try if
there's a process with that ID and return the first thread in it.
This makes it easier to print stack traces from the ps output.

init and fini handlers. Our vm system removes all userland mappings at
exit prior to calling pmap_release. It just so happens that we might
as well reuse the pmap for the next process since the userland slate
has already been wiped clean.
However. There is a functional benefit to this as well. For platforms
that share userland and kernel context in the same pmap, it means that
the kernel portion of a pmap remains valid after the vmspace has been
freed (process exit) and while it is in uma's cache. This is significant
for i386 SMP systems with kernel context borrowing because it avoids
a LOT of IPIs from the pmap_lazyfix() cleanup in the usual case.

Note that the mount point which is not accessible shows
up as the previous file system that was printed. The reason
for this is that df -t will call statfs(2) on the pathname
supplied by getfsstat(2).
This is done to refresh the file system statistics in the
event that a previous file system had a long delay in
providing its stats.
This change affects the df utility in the following ways:
o Teach df has to deal with statfs(2) failing. If statfs(2)
fails, fall back on the possibly stale stats provided by
the initial call to getfsstat(2).
o Print a warning that the fs stats could possibly be stale
o Modify the man page and document this new behavior
as a bug.

Also introduce a macro to be called by persistent nodes to signal their
persistence during shutdown to hide this mechanism from the node author.
Make node flags have a consistent style in naming.
Document the change.
This bring us several things:
- updated drivers
- IPv6 support at last
- ntp-genkeys is replaced by ntp-keygen
- ntptrace is now a script (courtesy of John Hay)
- lots of renamed files from .htm to .html (while I prefer .html, I
find the change a bit gratuitous)
- still no manpages :(
Please test and report.

may result

- Return meaningful return errorcodes.
- Free previously allocated connection in error cases.
In ng_device_rcvdata():
- Return meaningful return errorcodes.
- Detach mbuf from netgraph item, and free the item before
doing any other actions that may return from method.
- Do not call strange malloc() for buffer. [1]
- In case of any error jump to end, where mbuf is freed.
In ng_device_disconnect():

- Free disconnected connection.
style(9) in mentioned above functions:
- Remove '/* NGD_DEBUG */', when only one line is ifdef'ed.
- Remove extra braces to easier reading.
- Add space after comma in function calls.
