This ease Admin API administration, and also adds checking if qrexec
policy + scripts matches actual Admin API methods implementation.
The idea is to classify every Admin API method as either local
read-only, local read-write, global read-only or global read-write.
Where local/global means affecting a single VM, or the whole system.
See QubesOS/qubes-issues#2871 for details.

Implement this in two parts:
1. Permissions checks, getting a path from appropriate storage pool
2. Actual data import
The first part is done by qubesd in a standard way, but then, instead of
accepting all the data (which may be several GB), return a path to which
a shell script (in practice: `dd` command) will write the data.
Then the script call back to qubesd again to report success/failure and
qubesd response from that call is actually returned to the user.
This way we do not pass all the data through qubesd, but still can
control the process from there in a meaningful way. Note that the last
part (second call to qubesd) may perform all kind of verification (like
a signature check on the data, or so) and can also prevent VM from
starting (hooking also domain-pre-start event) from not verified image.
QubesOS/qubes-issues#2622
Install files in /etc/qubes-rpc for all methods defined in API
documentation, even if not yet implemented (qubesd will handle it
raising appropriate exception).
Use minimal program written in C (qubesd-query-fast), instead of
qubesd-query in python for performance reasons:
- a single qubesd-query run: ~300ms
- equivalent in shell (echo | nc -U): ~40ms
- qubesd-query-fast: ~20ms
Many tools makes multiple API calls, so performance here do matter. For
example qvm-ls (from VM) currently takes about 60s on a system with 24
VMs.
Also make use of `$include:` directive in policy file, to make it easier
defining a VM with full Admin API access.

This all either have been migrated to core3, or is not needed anymore.
There is still qvm-tools directory with a few tools that needs to be
migrated, or installed as is.
The following list is bollocks. There were many, many more.

This commit took 2 days (26-27.01.2016) and put our friendship to test.

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.
This libs are required by both dom0 and VM so it's better to have it
separately. Previously in VM it was separate package, but dom0 have them
embedded in qubes-core-dom0, but qubes-core-vm-libs package was used to build
qubes-gui-dom0. Now we do not build all packages for all distros (especially do
not build core-vm package for dom0 distro, so gui-dom0 build fails), so make it
explicit which package is needed by which system.
Some packages depends on kernel (ex fuse, pulseaudio), but kernel in VM is
managed by dom0. Any hack like exlude or so on will break some things, so
install empty placeholder package to fulfill dependencies.
