This process should be started from user session (most likely
qubes-session). New processes (of that user) will be created as
children of that session making logind and such crap happy. This should
also solve problems with EOF transmission (no additional "su" process)
and prevent loading all the environment multiple times.
Move (qrexec-agent version of) do_exec to qrexec-agent.c, move
handle_handshake to qrexec-agent-data.c (common to all agent binaries).
Fix indentation (tabs -> spaces).
The main advantage is possible use of single socket for both stdin and
stdout. This is strictly required for using USBIP over qrexec.
For compatibility qrexec still creates three socket pairs (instead of
pipes) for stdin/out/err respectively. When qrexec-agent receives
SIGUSR1, it will close stdout socket and use stdin socket for both
directions.
Some additional work is needed here to actually allow child process to
send that signal - qrexec is running as root, but child as "user" in
most cases.
Since the rules are no more directly handed to echo -e, sed needs to
handle all escape sequences used in rules (newline only, but in
different notations).
- Use copy-in for debian-quilt package in Makefile.builder instead of hook (to be removed) in Makefile.debian
- Remove patches from debian/patches; they are now applied dynamicly from series-debian-vm.conf

less restrictive permissions. /etc/udev/rules.d/99-qubes-misc.rules changes

Generate user-groups via -U instead of explicit via groupadd. This also
fix the problem that the tinyproxy group were not gererated as
"system"-group.
Also suppress unneeded output of the existence test.
Starting services in the postinst script doesn't make much sense since
the package is normally installed in the template. In addition the start
can fail when executed through a trigger.
/etc/iptables/rules.* are already part of the packet.
The removed code has never done something in debian (since
/etc/iptables/rules.* already exists).
