Add logging more info about each domain state:
- last requested target
- no_progress and slow_memset_react flags
This makes it unnecessary to log separately when those flags are cleared.
meminfo (written by VM) is expected report KiB, but qmemman internally
use bytes. Convert units.
And also move obscure unit conversion in is_meminfo_suspicious to more
logical place in sanitize_and_parse_meminfo.
Instead of excerpt from /proc/meminfo, use just one integer. This make
qmemman handling much easier and ease implementation for non-Linux OSes
(where /proc/meminfo doesn't exist).
For now keep also support for old format.
FixesQubesOS/qubes-issues#1312
This is part of fixing qvm-start.
qmemman was moved with minimal touching, mainly module names.
Moved function parsing human-readable sizes from core2. This function is
wrong, because it treats k/M/G as 1024-based, but leave it for now.
