[linux-lvm] lvm2 release 2.02.34

[Alasdair G Kergon]

I've uploaded lvm2 2.02.34 to ftp://sources.redhat.com/pub/lvm2/ .

It's a couple of months since the last release and some core functionality has
been tweaked, so I won't be surprised if new bugs have crept in - please
give it some testing!

The most significant changes were aimed at beginning to improve the
performance of the some of the tools by reducing the number of times
they go out to disk to read metadata.

The test suite (in the test subdirectory) is also advancing nicely.
