[lvm-devel] [PATCH 00/12] RFC & code review for lvm2app & python-lvm fixes

[Tony Asleson]

This patch set address the following bugs:

- Set PV metadata size and count
  https://bugzilla.redhat.com/show_bug.cgi?id=880395

- lvm2app lvm_vg_reduce() can delete a volume group
  https://bugzilla.redhat.com/show_bug.cgi?id=989174

- RFE: export a Python name-validation function
  https://bugzilla.redhat.com/show_bug.cgi?id=883689

In addition the following is included:

- Environmental variable LVM2APP_DEBUG if exists will cause the library to
  dump debug messages to stderr
- lvm2app -> lvm_errmsg will clear the error buffer so library users won't get
  stacked messages collecting for the entire run or until the buffer hits max.
  size.
- python-lvm was cleaned up to adhere to the expected namespace and includes
  a change to prevent segfaulting if a user call gc and then references an
  object with a stale library handle.
