[Libguestfs] [PATCH v4 00/11] virt-resize: add support for resizing MBR logical partitions

[Chen Hanxiao]

In current virt-resize, only primary partitions(including
extended partition) are supported. They are collected in an
array for resize operations. Logical partitions are not
supported.

This series add support for resizing logical partitions.

v4:
 rebase on upstream.

v3:
 1) rewrite partitions/logical_partitions/extended_partition section
  by the comments from Rich and Pino.
 2) in 03/11 introduce logical_align for reserve enough space
  when resizing logical/extended partitions.

v2:
 1) Add 3 variables to describe relationship of logical and extended partitions:
 - partitions
   flat list of primary partitions (as now, the global 'partitions').
    extended partitions is essentially  primary partition
 - logical_partitions
   flat list of logical partitions
 - extended_partition
   one MBR extended partition

  2) reserve enough size when resizing logical partitions
