450f272b31 devices: support printing the filter that rejects a device 
Use of this new message function needs to be added
to various commands to improve the output.

6620dc9475 add device hints to reduce scanning 
Save the list of PVs in /run/lvm/hints.  These hints
are used to reduce scanning in a number of commands
to only the PVs on the system, or only the PVs in a
requested VG (rather than all devices on the system.)

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/

and also saves indention level.

08d6d81cc2 filters: drop extra slash from sysfs path 
Sysfs filter was using '/sys//class/block' with double '//' inside.
Remove this extra '/'.
Also simplify code around and use loop to try those paths.

80bcdb93ff filters: check for mpath before opening devs 
Split out the partitioned device filter that needs to open the device
and move the multipath filter in front of it.

When a device is multipathed, sending I/O to the underlying paths may
cause problems, the most obvious being I/O errors visible to lvm if a
path is down.

Revert the incorrect <backtrace> messages added when a device doesn't
pass a filter.

Log each filter initialisation to show sequence.

Avoid duplicate 'Using $device' debug messages.
