f2d0cc63fd Remove dead code, is_lvm_partition() - no functional change. 
This code does nothing.  The function is #defined to 1 which ensures the only
two if statements referencing it will never be true.

626dd7a5fe Suppress 'sb_offset' compiler warning by using enum for md superblock versions. 
The warning is bogus and is only seen on certain versions of gcc.
However using the enum does seem to clarify the intent of the code - only
3 possible md minor superblock versions.

Related compiler warning:

Alasdair Kergon
25b733809a Merge with text format branch. 
Lots of changes/very little testing so far => there'll be bugs!

Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files.  Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.

Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).

e.g. metadata {
        dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}

Plenty of refinements still in the pipeline.

Alasdair Kergon
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.

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.
