Shmem pages are written in the same set of images as regular
pages are, but stats for those are not collected. Fix this, but
keep the counts separate to have more info.

The number of pipes are limited in a system, so it is better to know how
many we use.

When appropriate, the lazy pages will no be written to the destination.
Instead, a pagemap entry for range of such pages will be marked with 'lazy'
flag.

The pages that are mapped to zero_page_pfn are not dumped but information
where are they located is required for lazy restore.
Note that get_pagemap users presumed that zero pages are not a part of the
pagemap and these pages were just silently skipped during memory restore.
At the moment I preserve this semantics and force get_pagemap to skip zero
pages.

But keep @protobuf as a symlink: we have
this path encoded in sources. Gonna be
removed with time.
