[CRIU] [PATCH 27/32] tools: cpt2 -- Add "write" routines for virtual memory areas

[Cyrill Gorcunov]

Here we introduce writing of memory related stuff. In particular
VMAs areas, memory map and pages.

Because shared VMAs are to be written separately we gather them
into own hash.

Pages data read from openvz image file and wrote to page criu files,
this is inefficient and better to teach criu to work with page data
from openvz image file directly. But it's a target for further
optimization, for a while lets stick with trivial approach.

Also we convert only regular pages, other type of pages (iterator)
are to be converted someday latter.
