e582990901 If we run out of consumers while orphaning them, and the provider's geom 
is withering, destroy the provider when done.

This was exposed by the recent change to geom_dev's orphaning logic.

346cd5fe2d Implement g_call_me() as a way for geom methods to schedule operations 
to be performed in the event-thread.

To do this, we need to lock the eventlist with g_eventlock (nee g_doorlock),
since g_call_me() being called from the UP/DOWN paths will not be able to
aquire g_topology_lock.

This also means that for now these events are not referenced on any
particular consumer/provider/geom.

For UP/DOWN path use, this will not become a problem since the access()
function will make sure we drain any bio's before we dismantle.

of the last commit message.

get notified to make things settle a bit faster.

855f8b26f2 Only clear the spoiled flag if the class had no spoiled method, the spoiled 
method may have deallocated the consumer already and modifying free()'ed
memory is bad style.

6008862bc2 Change callers of mtx_init() to pass in an appropriate lock type name. In 
most cases NULL is passed, but in some cases such as network driver locks
(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

Tested on:	i386, alpha, sparc64

b1876192f0 Eliminate some thread pointers which do not make sense anymore. 
Split private parts of geom.h into geom_int.h.  The latter should
never be included in class implemtations.

dd84a43c1d First commit of the GEOM subsystem to make it easier for people to 
test and play with this.

This is not yet production quality and should be run only on dedicated
test boxes.

For people who want to develop transformations for GEOM there exist a
set of shims to run geom in userland (ask phk@freebsd.org).

Reports of all kinds to: phk@freebsd.org
Please include in report:
        dmesg
        sysctl debug.geomdot
        sysctl debug.geomconf

Known significant limitations:
        no kernel dump facility.
        ioctls severely restricted.
