a41aa4a789 Escape characters unsafe for XML output in GEOM class, instance and
provider names.

- Characters in range 0x01-0x1f except '\t', '\n', and '\r' are replaced
  with '?'. Those characters are disallowed in XML.
- '&', '<', '>', '\'', '"' and characters in range 0x7f-0xff are
  replaced with XML numeric character reference.

If the kern.geom.confxml sysctl provides invalid XML, libgeom
geom_xml2tree() fails and utilities using it do not work. Unsafe
characters are common in msdosfs and cd9660 labels.

d40f7f8b3e Make the kern.geom.conftxt sysctl more usable by also dumping the
MD class. Previously only the DISK class was dumped. The only
consumer of this sysctl is libdisk (i.e. sysinstall) and it tests
explicitly for instances of the DISK class. Dumping other classes
is therefore harmless.
By also dumping the MD class regression tests can be written that
use the MD class for operations that would normally be done on the
DISK class. The sysctl can now be used to test if those operations
took an effect. An example is partitioning.

3d1d5bc3c3 Rearrange some of the GEOM debugging tools to be more structured.
Retire g_sanity() and corresponding debugflag (0x8)

  Retire g_{stall,release}_events().

  Under #ifdef DIAGNOSTIC:

    Make g_valid_obj() an official function and have it return an an
    non-zero integer which indicates the kind of object when found.

    Implement G_VALID_{CLASS,GEOM,CONSUMER,PROVIDER}() macros based
    on g_valid_obj().

    Sprinkle calls to these macros liberally over the infrastructure.

    Always check that we do not free a live object.

3924ad705e 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.

afcbcfaed0 Change events to have an array of "void *" references, and give the
event posting functions varargs to fill these.

Attribute g_call_me() to appropriate g_geom's where necessary.

Add a flag argument to g_call_me() methods which will be used to signal
cancellation of events in the future.

This commit should be a no-op.

b4b138c27f Including <sys/stdint.h> is (almost?) universally only to be able to use

801bb689ca Commit the correct copy of the g_stat structure.
Add debug.sizeof.g_stat sysctl.

Set the id field of the g_stat when we create consumers and providers.

Remove biocount from consumer, we will use the counters in the g_stat
structure instead.  Replace one field which will need to be atomically
manipulated with two fields which will not (stat.nop and stat.nend).

Change add companion field to bio_children: bio_inbed for the exact
same reason.

Don't output the biocount in the confdot output.

Fix KASSERT in g_io_request().

Add sysctl kern.geom.collectstats defaulting to off.

Collect the following raw statistics conditioned on this sysctl:

    for each consumer and provider {
        total number of operations started.
        total number of operations completed.
        time last operation completed.
        sum of idle-time.
        for each of BIO_READ, BIO_WRITE and BIO_DELETE {
            number of operations completed.
            number of bytes completed.
            number of ENOMEM errors.
            number of other errors.
            sum of transaction time.
        }
    }

07107de9bc Introduce the concept of "magic spaces", and implement them in most of
the relevant classes.

Some methods may implement various "magic spaces", this is reserved
or magic areas on the disk, set a side for various and sundry purposes.
A good example is the BSD disklabel and boot code on i386 which occupies
a total of four magic spaces: boot1, the disklabel, the padding behind
the disklabel and boot2.  The reason we don't simply tell people to
write the appropriate stuff on the underlying device is that (some of)
the magic spaces might be real-time modifiable.  It is for instance
possible to change a disklabel while partitions are open, provided
the open partitions do not get trampled in the process.

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.
