6472ac3d8a Mark all SYSCTL_NODEs static that have no corresponding SYSCTL_DECLs.
The SYSCTL_NODE macro defines a list that stores all child-elements of
that node. If there's no SYSCTL_DECL macro anywhere else, there's no
reason why it shouldn't be static.

e7926a3703 Reimplemented "gpart destroy -F". Now it does all work in kernel.
This was needed for recover implementation.

Implement the recover command for GPT. Now GPT will marked as
corrupt when any of three types of corruption will be detected:
1. Damaged primary GPT header or table
2. Damaged secondary GPT header or table
3. Secondary header is not located in the last LBA
Marked GPT becomes read-only. Any changes with corrupt table
are prohibited. Only "destroy" and "recover" commands are allowed.

6f702278e6 Fix undo for schemes that have internal partitions. Internal partitions
do not constitute user-visible or active partitions and as such should
not prevent undoing pending operations.

While here, initialize the last usable sector for the placeholder geom
based on the null scheme, created to allow undoing the destruction of
a scheme. This gives consistent output with "gpart show".

0c8fd0c8ac Change the way in which zero stripesize is handled. Instead of reporting
zero stripeoffset in such case (as if device has no stripes), report offset
from the beginning of the media (as if device has single infinite stripe).

This gives partitioning tools information, required to guess better
partition alignment, in case if hardware doesn't report it's stripe size.
For example, it should give disklabel info about odd offset made by fdisk.

f8727e71d7 If provider is open for writing when we taste it, skip it for classes that
depend on on-disk metadata. This was we won't attach to providers that are used
by other classes. For example we don't want to configure partitions on da0 if
it is part of gmirror, what we really want is partitions on mirror/foo.

During regular work it works like this: if provider is open for writing a class
receives the spoiled event from GEOM and detaches, once provider is closed the
taste event is send again and class can rediscover its metadata if it is still
there.  This doesn't work that way when new class arrives, because GEOM gives
all existing providers for it to taste, also those open for writing. Classes
have to decided on their own if they want to deal with such providers (eg.
geom_dev) or not (classes modified by this commit).

f43b57e32a Revert revisions 188839 and 188868. Use of the ioctl in geom_dev.c
is invalid because the ioctl happens without prior open. The ioctl
got introduced to provide backward compatibility for extended
partitions, but it ended up not being used because it didn't work
as expected. Since there are no consumers of the ioctl and the
implementation is broken, the best fix is to remove the code
entirely.

94dd506d54 Make GEOM provider names starting with "/dev/" acceptable as well as their
"raw" names. While there, change the formatting of extended MSDOS partitions
so that the dot (".") is not used to separate two numbers (which kind of
looks like the whole is a decimal number). Use "+" instead, which also
hints that the second part of the name is the offset from the start of
the partition in the first part of the name. Also change the offset from
decimal to hexadecimal notation, simply for aesthetic reasons and future
compatibility.

GEOM_PART is the default in 8-CURRENT but not yet in 7-STABLE so this
changeset can be MFC-ed without causing major problems from the second
part.

59c532c500 Provide compatibility symlink for logical partitions:
1.  Extend geom_dev by having it create the symlink (i.e. call
    make_dev_alias) based on the DIOCGPROVIDERALIAS ioctl.
    In this way the functionaility is generic and thus usable
    by any geom/provider.
2.  Have g_part handle said ioctl through the devalias method,
    so that it's under control of the scheme itself. By design
    the alias will not be created for newly added partitions.

7ca4fa83ec Add method precheck to the g_part interface. The precheck
method allows schemes to reject the ctl request, pre-check
the parameters and/or modify/set parameters. There are 2
use cases that triggered the addition:
1.  When implementing a R/O scheme, deletes will still
    happen to the in-memory representation. The scheme is
    not involved in that operation. The pre-check method
    can be used to fail the delete up-front. Without this
    the write to disk will typically fail, but at that
    time the delete already happened.
2.  The EBR scheme uses a linked list to record slices.
    There's no index. The EBR scheme defines the index
    as a function of the start LBA of the partition. The
    add verb picks an index for the range and then invokes
    the add method of the scheme to fill in the blanks. It
    is too late for the add method to change the index.
    The pre-check is used to set the index up-front. This
    also (silently) overrides/nullifies any (pointless)
    user-specified index value.

165651a553 o Add the "PART::scheme" attribute that returns the name of the
underlying partitioning scheme.
o  Put the start and end of the partition in the XML configuration.
   The start and end are the LBAs of the first and last sector
   (resp.) of the partition. They are currently identical to the
   offset and size attributes, which describe the partition as an
   offset and size in bytes, but may not in the future. The start
   and end will be used for the logical partition boundaries and
   may include metadata. The offset and size will always represent
   the useful storage space within the partition. Typically these
   two notions are the same, but for logical partitions in an
   extended partition, the EBR is more naturally treated as being
   part of the partition.
