Default `ask` policy ignore target domain specified by the caller, so it
doesn't make sense to specify one. Provide convenient wrappers not
needing one. Do not change behaviour of existing tools for compatibility
reasons.

Explicitly block something like "curl http://127.0.0.1:8082" and
return error page in this case. This error page is used in Whonix to
detect if the proxy is torrified. If not blocked, it may happen that
empty response is returned instead of error. See linked ticket for
details.
This was previously done for 10.137.255.254, but since migration to
qrexec-based connection, 127.0.0.1 is used instead.

* qubesos/pr/53:
Handle fallthrough with attribute(noreturn) for consistancy and compatiblity with older GCC
Add CENTOS/RHEL support (drop fedora-release dependancy as template builder will install it anyway and here it only make harder to support non-fedora builds)
Few reasons for this:
1. new templates use dnf to download packages, so yum.conf is unused
2. dom0 in Qubes 4.0 don't have this file at all (so sed fails here)
3. $OPTS already contains --setopt=reposdir=...

Some services require GUI access. Make qrexec-agent handling this, based
on per-service configuration, instead of forcing every caller to call
qubes.WaitForSession service first. This is especially important for
Disposable VMs, because those are destroyed after a single service call.
This needs to be done in qrexec-agent (instead of service script, or
qubes-rpc-multiplexer), because agent will behave differently depending
on GUI session being available or not. Namely, will use
qrexec-fork-server (so the process will be a child of session leader),
or will open new session.
Service configuration lives in /etc/qubes/rpc-config/SERVICE_NAME, can
can contain 'key=value' entries (no space around '=' allowed). Currently
the only settings supported is 'wait-for-session', with value either '0'
or '1'.

Prepend "-" to shell name, to instruct it being a login shell. This way
shell will initialize environment, load /etc/profile etc.

Since some systemd services are moved to other packages, appropriate
%post/%preun should contain the code to enable/disable them.

clock synchronization mechanism rewritten to use systemd-timesync instead of NtpDate; at the moment, requires:
- modifying /etc/qubes-rpc/policy/qubes.GetDate to redirect GetDate to designated clockvm
- enabling clocksync service in clockvm ( qvm-features clockvm-name service/clocksync true )
Works as specified in issue listed below, except for:
- each VM synces with clockvm after boot and every 6h
- clockvm synces time with the Internet using systemd-timesync
- dom0 synces itself with clockvm every 1h (using cron)

When there is only console=hvc0 (i.e. no output to emulated VGA) and
GRUB_TIMEOUT is set to 0, VM startup hangs. This may be very well some
race condition broken by either of console=tty0 or GRUB_TIMEOUT > 0, but
even in such a case, apply this as a workaround for now.
Instead of calling 'su' to switch the user, use own implementation of
this. Thanks to PAM it's pretty simple. The main reason is to have
control over process waiting for session termination (to call
pam_close_sesion/pam_end). Especially we don't want it to keep std* fds
open, which would prevent qrexec-agent from receiving EOF when one of
them will be closed.
Also, this will preserve QREXEC_AGENT_PID environment variable.

It isn't really needed. It was used to workaround libusb bug (causing
crash when the system does not have any USB controller), but since we
use HVM now which do have some USB controllers it isn't needed anymore.
Also, it is not available in stock Fedora kernels.
When qrexec-client-vm is started with socket on its stdout and no local
process requested, it will try to shutdown(SHUT_WR) this socket when
remote process exists. This is wrong, because this socket may be still
needed by other processes (for example shell from where qrexec-client-vm
was called).
In such a case, simple close() should be used.
