1539e51721 devices: clean up io error messages
Remove the io error message from bcache.c since it is not
very useful without the device path.

Make the io error messages from dev_read_bytes/dev_write_bytes
more user friendly.

bd7cdd0b09 lvconvert: support linear <-> striped convenience conversions
"lvconvert --type {linear|striped|raid*} ..." on a striped/linear
LV provides convenience interim type to convert to the requested
final layout similar to the given raid* <-> raid* conveninece types.

Whilst on it, add missing raid5_n convenince type from raid5* to raid10.

c516321325 lvmlockd: enable lvcreate of new LV plus existing cache pool
In this command, lvcreate creates a new LV and then combines
it with an existing cache pool, producing a cache LV.  This
command was previously not allowed in in a shared VG.

6cd0523337 lvmlockd: enable repairing shared VG while reading it
When the lvmlockd lock is shared, upgrade it to ex
when repair (writing) is needed during vg_read.

Pass the lockd state through additional read-related
functions so the instances of repair scattered through
vg_read can be handled.

(Temporary solution until the ad hoc repairs can be
pulled out of vg_read into a top level, centralized
repair function.)

3c9ed33f83 scan: move warnings about duplicate devices
We have been warning about duplicate devices (and disabling lvmetad)
immediately when the dup was detected (during label_scan).  Move the
warnings (and the disabling) to happen later, after label_scan is
finished.

This lets us avoid an unwanted warning message about duplicates
in the special case were md components are eliminated during the
duplicate device resolution.

ccc35e2647 device-mapper: Fork libdm internally.
The device-mapper directory now holds a copy of libdm source.  At
the moment this code is identical to libdm.  Over time code will
migrate out to appropriate places (see doc/refactoring.txt).

The libdm directory still exists, and contains the source for the
libdevmapper shared library, which we will continue to ship (though
not neccessarily update).

All code using libdm should now use the version in device-mapper.

7f97c7ea9a build: Don't generate symlinks in include/ dir
As we start refactoring the code to break dependencies (see doc/refactoring.txt),
I want us to use full paths in the includes (eg, #include "base/data-struct/list.h").
This makes it more obvious when we're breaking abstraction boundaries, eg, including a file in
metadata/ from base/

09fcc8eaa8 scan: ignore duplicates that are md component devs
md devices using an older superblock version have
superblocks at the end of the md device.  For commands
that skip reading the end of devices during filtering,
the md component devs will be scanned, and will appear
as duplicate PVs to the original md device.  Remove
these md components from the list of unused duplicate
devices, so they are treated as if they had been
ignored during filtering.  This avoids the restrictions
that are placed on using PVs with duplicates.
