95959703e1 Sector size can not be greater than MAXPHYS. Since GRAID3 calculates

946e2f3595 - Remove gc_argname field. It was introduced for gpart(8), but if I
understand everything correctly, we don't really need it.
- Provide default numeric value as strings. This allows to simplify
  a lot of code.
- Bump version number.

3cf55d3ab9 Add gpart(8).
In order to support gpart(8), geom(8) needs to support a named
argument. Also, optional string parameters are a requirement.
Both have been added to the infrastructure. The former required
all existing classes to be adjusted.

power failure or system crash.

f13942a746 - The geom(8) utility only uses three types of arguments: string (char *),
value (intmax_t) and boolean (int).
  Based on that provide three functions:
        - gctl_get_ascii()
        - gctl_get_int()
        - gctl_get_intmax()
- Hide gctl_get_param() function, as it is only used internally in
  subr.c.
- Allow to provide argument name as (fmt, ...).
- Assert geom(8) bugs (missing argument is a geom(8) bug).

- Clean-up and simplify the code by using new functions and assumtions
  (no more checking for missing argument).

e68909854c - Add md_provsize field to metadata, which will help with
shared-last-sector problem.
  After this change, even if there is more than one provider with the same
  last sector, the proper one will be chosen based on its size.
  It still doesn't fix the 'c' partition problem (when da0s1 can be confused
  with da0s1c) and situation when 'a' partition starts at offset 0
  (then da0s1a can be confused with da0s1 and da0s1c). One can use '-h'
  option there, when creating device or avoid sharing last sector.
  Actually, when providers share the same last sector and their size is equal,
  they provide exactly the same data, so the name (da0s1, da0s1a, da0s1c)
  isn't important at all.
- Provide backward compatibility.
- Update copyright's year.

a245a5483c - Add genid field to the metadata which will allow to improve reliability a bit.
After this change, when component is disconnected because of an I/O error,
  it will not be connected and synchronized automatically, it will be logged
  as broken and skipped. Autosynchronization can occur, when component is
  disconnected (on orphan event) and connected again - there were no I/O
  error, so there is no need to not connected the component, but when there were
  writes while it wasn't connected, it will be synchronized.
  This fix cases, when component is disconnected because of I/O error and can be
  connected again and again.
- Bump version number.
- Implement backward compatibility mechanism. After this change when metadata in
  old version is detected, it is automatically upgraded to the new (current)
  version.

dba915cfee Implementation of 'verify reading' algorithm, which uses parity data for
verification of regular data when device is in complete state.
On verification error, EIO error is returned for the bio and sysctl

f5a2f7feac Implement new reading algorithm, which will use parity component for reading
as well, even if device is in complete state.
I observe 40% of speed-up with this option for random read operations,
but slowdown for sequential reads.
Basically, without this option reading from a RAID3 device built from 5
components (c0-c4) looks like this:

	Request no.	Used components
	1		c0+c1+c2+c3
	2		c0+c1+c2+c3
	3		c0+c1+c2+c3

With the new feature:

	Request no.	Used components
	1		c0+c1+c2+c3
	2		(c1^c2^c3^c4)+c1+c2+c3
	3		c0+(c0^c2^c3^c4)+c2+c3
	4		c0+c1+(c0^c1^c3^c4)+c3
	5		c0+c1+c2+(c0^c1^c2^c4)
	6		c0+c1+c2+c3
