d17a8e365d Make _init_rand() thread safe - use rand_r() instead of rand(). 
Use good entropy for seed value if possible.

a4a1cd76ba Fix allocation bug in text metadata format write error path. 
Function _text_pv_write doesn't use memory pool but static buffer,
call dm_pool_free in error path in _raw_write_mda_header is wrong.

Move pool free only to path where is the memory pool used.

d2edd6ac07 Add pvcreate sanity tests, check for label_write() failure in _text_pv_write(). 
Failure to check for label_write() return code caused the following test
to indicate it passed when it really failed:
pvcreate rejects labelsector > 1000000000000

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.

e74999af51 o Add cmd_line field to struct cmd_context 
o  Text format now has a description and time field at the top level.

o  archiving and backup set the description appropriately. eg,

   for an archive:

     description = "Created *before* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

   for a backup:

     description = "Created *after* executing 'lvextend test_vg/lvol0 -l +1'."
     creation_time = 1013166332

This is preparing the way for a simple vgcfgundo command.
