- In case the parent is bge(4), don't set the Jumbo frame settings unless
the MAC actually is Jumbo capable as otherwise the PHY might not have the
corresponding registers implemented. This is also in line with what the
Linux tg3 driver does.

termination of the supervisor after removing the pidfile.
This looks like desirable behavior, because termination of a
supervisor usually supposes termination of its charge. Also it will
fix the issue with stale pid files after reboot due to init kills a
supervisor before its child exits.

not to leak the descriptor after exec(3). This raises the issue for
daemon(3) of the pidfile lock to be lost when the child process
executes.
To solve this and also to have the pidfile cleaned up when the program
exits, if a pidfile is specified, spawn a child to exec the command
and wait in the parent keeping the pidfile locked until the child
process exits and remove the file.

hold the lock.
This is part of my series of work to try and capture when net80211
locking isn't.
ObNote: it'd be nice to be able to mark a lock as "assert if the lock
is dropped", so I could capture functions which decide that dropping
and reacquiring the lock is a good idea (without re-checking the
sanity of the state protected by the lock.)
Without this change, pressing ^T could result in rc.d script putting

Script <filename> running

Vnode-backed mappings cannot be put into the kernel map, since it is a
system map.
Use exec_map for transient mappings, and remove the mappings with
kmem_free_wakeup() to notify the waiters on available map space.
Do not map the whole executable into KVA at all to copy it out into
usermode. Directly use vn_rdwr() for the case of not page aligned
binary.
There is one place left where the potentially unbounded amount of data
is mapped into exec_map, namely, in the COFF image activator
enumeration of the needed shared libraries.

This allows all of the athstats statistics to work again.
Specifics:
* The previous code used chars < 0x80 as printable, and chars >= 0x80
as "statistics"
* .. which meant any statistic above 127 would wrap around to 0;
* .. so once I added the 802.11n TX/RX statistics to athstats, the tail
end of the statistics list weren't accessible.
This patch:
* adds a define which represents the magic character, rather than a hard
coded one
* the statistic in question is little endian encoded after the magic
character.
Notes:
* statfoo is useful enough to possibly warrant turning into a library API.

At 16 FIBs a total of over 64k return codes/replies/stati are checked,
sometimes multiple times (in different ways, e.g. the reflected request
as well as ipfw counter values).
The scripts need two or three machines to run and are thus not added

The previous code did not limit the I/O request size based on

- Make hash sizes growable, to satisfy users running large mpd
installations, having thousands of nodes.
- NG_NAMEHASH() proved to give a very bad distribution in real life
name sets, while generic hash32_str(name, HASHINIT) proved to give
an even one, so you the latter for name hash.
- Do not store unnamed nodes in slot 0 of name hash, no reason for that.
- Use the ID hash in cases when we need to run through all nodes: the
NGM_LISTNODES command and in the vnet_netgraph_uninit().
- Implement NGM_LISTNODES and NGM_LISTNAMES as separate code, the former
iterates through the ID hash, and the latter through the name hash.
- Keep count of all nodes and of named nodes, so that we don't need
to count nodes in NGM_LISTNODES and NGM_LISTNAMES. The counters are
also used to estimate whether we need to grow hashes.
- Close a race between two threads running ng_name_node() assigning same
name to different nodes.
