b849de1d18 Fix the device cache to cope reasonably safely with device name changes.
This should be a rare occurrence so the aim is to recover if it's
straightforward to do so, otherwise just to abort the operation.
If people *knowingly* change device names, they should always run vgscan
afterwards.

A few bytes of memory gets leaked inside a pool each time an alias
has to be discarded - it's not worth restructuring the code to reuse it.

More of LVM2 needs updating to pass device objects (or uuids) about
instead of pathnames so that resolution of pathname->object only happens
once per operation.

dev_cache_get() should now always return the *current* device at the path given

dev_name_confirmed() replaces dev_name() whenever it's important to
know that name for the device is still current (ie when opening it).
If the cache doesn't know a current name, the function fails.

dev_open() guarantees that the file descriptor returned is for the dev_t
of the device structure it was passed.

7743c8685e Clear a FIXME about checking for identical devices by comparing dev_t
instead of name.

610c25e8b1 o Remove redundant symlink-handling code.
o When opening device, return error if its cached name is incorrect (eg if
  it's changed since the cache was generated).  This prevents use until
  the cache is rebuilt (eg with vgscan).  Doesn't catch every case.
