Add --dataalignment to pvcreate to specify alignment of data area.  (mbroz)

Intended behaviour of the code now:

  pe_start in the lvm2 format PV label header is set only by pvcreate (or
vgconvert -M2) and then preserved in *all* operations thereafter.

  In some specialist cases, after the PV is added to a VG, the pe_start
field in the VG metadata may hold a different value and if so, it
overrides the other one for as long as the PV is in such a VG.

  Currently, the field storing the size of the data area in the PV label
header always holds 0.  As it only has meaning in the context of a
volume group, it is calculated whenever the PV is added to a VG (and can
be derived from extent_size and pe_count in the VG metadata).

Move initialization of cmd->fmt into init_formats().

init_formats() sets up the command formats, and currently sets cmd->fmt_backup

set it to cmd->default_settings.fmt before returning.

The call we remove here may set cmd->fmt based on a command line setting.
But it is safe to remove this, because the only caller of init_lvm() that

areas of the code so here we add a 'enabled' paramter to archive_init().
We pass in cmd->default_settings.archive, which is obtained from the

But it does not call init_test().  So we need an init_test() somewhere.
The most logical place is to put it inside _init_logging(), since this
is where the config value is read and default_settings are set.  Placing
the init_test() call here matches what is done with other variables and
