8107ecf892 - Change all places where G_TYPE_ASCNUM is used to G_TYPE_NUMBER.
It turns out the new type wasn't really needed.
- Reorganize code a little bit.

315fcbf7db Add G_TYPE_MULTI flag, which when set for the given option, will
allow the option to be specified multiple times. This will help to
implement things like passing multiple keyfiles to geli(8) instead of
cat(1)ing them all into stdin and reading from there using one '-k -'
option.

79d89bb0ab Remove G_TYPE_ASCLBA type and replace it with G_TYPE_STRING in gpart.
Move code that converts params from humanized numbers to sectors count
to subr.c and adjust comment.
Add post-processing for "size" and "start offset" params in gpart,
now they are properly converted to sectors count with known sector size
that can be greater that 512 bytes.
Also replace "unsigned long long" type to "off_t" for unify code since
it used for medium size in libgeom(3) and DIOCGMEDIASIZE ioctl.

file to be of maximum size.
- Add special handling required for SMI/VTOC8 disklabel partcode, i.e. avoid
  overwriting the label when writing the bootstrap code to the partition
  starting at 0 and install it to all partitions when the -i option is omitted
  just like geom_sunlabel(4) and sunlabel(8) do by default.
- Add missing prototypes.

1831a90ac5 Bring in geom_sched, support for scheduling disk I/O requests
in a device independent manner. Also include an example anticipatory
scheduler, gsched_rr, which gives very nice performance improvements
in presence of competing random access patterns.

This is joint work with Fabio Checconi, developed last year
and presented at BSDCan 2009. You can find details in the
README file or at

2b4969ff9e Change how multipath labels are created and managed. This makes it easier
to support various storage boxes which really aren't active-active.

We only write the label on the *first* provider. For all other providers
we just "add" the disk. This also allows for an "add" verb.

A usage implication is that you should specificy the currently active
storage path as the first provider.

Note that this does not add RDAC-like functionality, but better allows for
autovolumefailover configurations (additional checkins elsewhere will support
this).

b3f9d8c804 Add gmountver, disk mount verification GEOM class.
Note that due to e.g. write throttling ('wdrain'), it can stall all the disk
I/O instead of just the device it's configured for.  Using it for removable
media is therefore not a good idea.

2cf8fb9be3 Increase default block size from 4K to 64K. It was reduces 6 yeard ago,
when trees were big and FAST mode was enabled by default.

So small block size doesn't benefits linear I/O operations in FAST and
significantly slowdowns in ECONOMIC (default) mode. For single stream random
I/Os so small block doesn't give much benefits, as access time is usually
bigger then transfer time there. Same time it requires all heads to seek
together for every single request, reducing performance on parallel load.

20cad71f00 Change gmirror default balance algorithm from "split" to "load".
"split" is very ineffective for devices with rotating media as HDDs.
To be effective, it needs that transfer time reduction due to block
splitting was bigger then access time increase due to non-sequential
access. For modern HDDs I was able to reproduce it only with read sizes
of 2MB and above, which is almost not applicable in real life.
"load" algorithm same time is more universal and effective now.
