c411519220 qmemman: do not trim the mem-set value too much 
We used to mem-set the domain to 0.995*calculated_value; 5 promils of 4GB
is ca 19MB, and it is too visible. Use 0.999 instead of 0.995

0c1f21a28e qmemman: when a AppVM is low on memory, allow small adjustments 
A small AppVM (say, with 100MB total) can go below prefmem, and
still not be assigned memory, because of the MIN_TOTAL_MEMORY_TRANSFER
threshold.
So, if AppVM is below prefmem, allow for smaller mem-sets.

f6e3607d2d qmemman: offload some processing to meminfo-writer 
Make meminfo-writer compute used memory, and report to qmemman only if
it has changed significantly enough. As it is written in C, its code is
much faster that qmemman-server; also in the idle case, it saves on xenstore
communication overhead. Allows to send updates up to 10 times per second,
with CPU load on the VM below 0.1%.

24b3baf063 qmemman: use 'Memtotal' from /proc/meminfo to calculate used memory 
Previously, memory_actual (retrieved from xen) was used; it can be inconsistent.
'Memtotal' can be spoofed, but anyway we rely on other fields from /proc/meminfo.

5a33ed71ce qmemman: use the fact that balloon driver retries 
Apparently even if there is not enough xen memory to balloon up,
balloon driver will try to fulfill the request later, when
some memory is freed. Thus, in do_balloon, do not limit mem_set
to the available memory.

22df517425 qmemman: detect domain list change by watching /vm, not /local/domain

10408d61db qmemman: when low on memory, do not make a VM go below prefmem 
Now the balance() has two different cases: enough memory and low_on_memory.
In the former, distribute memory proportianally; in the former, dont do this, as this
makes a VM go below prefmem.

filename. The content of the file will be copied (via xenstore) to DVM
and executed just before save. This makes it possible to preload memory
with useful apps.

8da2dd6957 Get rid of dnsmasq in netvm. 
qubes_setup_dnat_to_ns script sets up DNAT rules for DNS traffic; it is
triggered by dhclient or NetworkManager, and manually (in case there is
a static resolv.conf).

Put IP-dependent rules in qubes-core, after local ip is known. It could be
further improved by introducing custom chains, to enable iptables save.

Restrict FORWARD.
