da80cf8fcc Appearantly UFS no longer issues BIO_DELETE requests correctly, and 
consequently trashes data.  Disable BIO_DELETE handling in gbde for now.

876e7e7a6d Do an explicit retry after we have dumped the cache, rather than a 
(potential) tail recursion.

82e4f296ff If on a BIO_READ request, we failed to allocate the bio for reading 
our key-sector, we would end up returning the read without an error,
despite the fact that the data was not correctly decrypted.

This would result in data corruption on read, but intact data still
on the media.

017246b9b8 Fix a problem and slightly improve the ENOMEM handling: 
Give up the entire bio as soon as we detect a problem.

When we detect a problem, give up the bio by contributing the
remainder with ENOMEM, rather than kicking the bio back right
away.

If we failed on a non-first iteration we previously could end up
modifying fields in the bio after we delivered it.  This could
account for memory corruption (none directly reported) on machines
with GBDE.

ffd04bfbdd Introduce a g_waitfor_event() function which posts an event and waits for 
it to be run (or cancelled) and use this instead of home-rolled versions.

1e2ee18100 Change the locking so that the _modify function is called with topology 
held.

The only place where we want to not hold topology is when we read
(or write) the label to disk: in the case of a disk error with a
long recovery time, holding topology would prevent open/close of
any disk device.

13d95d603f Do not mandate that slicers have a private ->start(), they may not need 
one.  KASSERT() that they have one if G_SLICE_HOT_START is used.

c99d9e1424 Implement a hotspot for the sunlabel. 
This means that you can no longer trash your opened partitions by writing to
the sunlabel through another partition.  This is similar to the semantics
implemented for BSD labels.

db4d21ffaf Make more of the "hotspot" stuff generic: 
Give the class a way to specify the necessary action for read/delete/write:
ALLOW, DENY, START or CALL.

Update geom_bsd to use this.

03b1ca36ba Time has run from the "run GEOM in userland" harness, and the new regression 
test is built to test GEOM as running in the kernel.

This commit is basically "unifdef -D_KERNEL" to remove the mainly #include
related code to support the userland-harness.

b08878d5ab Retire the "frontstuff" record keeping, it was no match for the

b62dc48437 With the magic sequence checks removed this class is downright dangerous 
to have in your kernel since it indiscriminately attaches to anything
it is offered with a range of bogus partitions.

Stop this from happening by rejecting any label with negative numbers in
it.
