576dd1fc41 radix-tree: First drop of radix tree.
An implementation of an adaptive radix tree.  Has the following nice
properties:

  - At least as fast as the hash table
  - Uses less memory
  - You don't need to give an expected size when you create
  - It scales nicely (ie. no large reallocations like the hash table).
  - You can iterate the keys in lexicographical order.

Only insert and lookup are implemented so far.  Plus there's a lot
more performance to come.

57bb46c5e7 filter: use bcache for filter reads
Filters are still applied before any device reading or
the label scan, but any filter checks that want to read
the device are skipped and the device is flagged.

After bcache is populated, but before lvm looks for
devices (i.e. before label scan), the filters are
reapplied to the devices that were flagged above.
The filters will then find the data they need in
bcache.

ed837e6971 Revert "build: Calculate dependencies at same time as compiling."
This reverts commit 0931067dc5.

The dep files should be in the build dir, which is not necc. the src dir.

Easy to fix, but reverting for now until I have time to revisit.

c016b573ee clvmd: separate saved_vg from vginfo
The clvmd saved_vg data is independent from the normal lvm
lvmcache vginfo data, so separate saved_vg from vginfo.
Normal lvm doesn't need to use save_vg at all, and in clvmd,
lvmcache changes on vginfo can be made without worrying
about unwanted effects on saved_vg.

a5e13f2eef clvmd: defer freeing saved vgs
To avoid the chance of freeing a saved vg while another
code path is using it, defer freeing saved vgs until
all the lvmcache content is dropped for the vg.

4ebfd8e8eb lvconvert: don't return success on degraded -m raid1 conversion
In case "lvconvert -mN RaidLV" was used on a degraded
raid1 LV, success was returned instead of an error.

Provide message to inform about the need to repair first
before changing number of mirrors and exit with error.

Add new lvconvert-m-raid1-degraded.sh test.

972b535220 build: add -D_FILE_OFFSET_BITS=64
I don't like having this in a common header because it means you end
up including too much and causing unneccessary dependencies.  eg,
lib/misc/lib.h includes libdevmapper.h, internationalisation, and
logging stuff.
