CA-41832: clip the target of an 'inactive' domain to be within dynamic_min/dynamic_max
This is potentially dangerous: the reason we attempt to cap the memory usage of an unresponsive domain is to prevent it suddenly waking up and allocating at a bad moment, resulting in either a transient OOM or loss of low memory. With this change the cap will be 'loose', where target can be higher than memory_actual.

The recent addition of the VDI on_boot and allow_caching parameters affected the allowed operations check. The additional check was put in

MAR-112: RRD transfer lock can prevent master transition
If the master loses connectivity during a RRD transfer, the RRD mutex
will never be released. When performing a emergency master transition,
the first thing that occurs is to save the local RRDs to disk, which
requires the RRD mutex. This will never succeed, thus XAPI gets stuck
trying to shut down.
Instead of locking the mutex, we try to acquire it for a few seconds.
If the lock can not be taken, the loss of some RRD data is preferable
to not being able to transition at all.

Update firstboot network data before pool eject
When a host is ejected from a pool, its XAPI database objects are removed and recreated by the firstboot scripts after the host reboots. The data used by the firstboot scripts is stored when the host is installed, and never updated anymore after that. Part of the firstboot data is the assignment and IP configuration of the management interface.
This patch updates the firstboot data to reflect the current configuration of the management interface on pool eject, such that after the reboot, management is configured in the same way as before. As pool eject removes any bonds, in case management is on a bond, one of the slaves is chosen to become the new management interface.

Rewrite feature restrictions code
This patch replaces restrictions.ml by features.ml and editions.ml, and splits up license.ml in three separate files (license.ml, license_init.ml and license_file.ml).
The Features module controls which XCP features are enabled. The Editions module defines "editions", which are sets of features that are enabled. An XCP host is always running as (exactly) one particular edition. Currently, there is just one edition defined, called "Free" (for backwards compatibility), in which all currently implemented features are enabled.
One use of this is that new or experimental features can be enabled only in special editions to keep them separate from the stable version of XCP.

Improve import of networks/VIFs on pool join
Metadata export+import is used to recreate VIFs on the pool, when a host joins. VIFs are linked to networks on the receiving pool by matching the name_label of the network on the two pools. If the name_label does not exist, this has to be because an existing physical network on the receiving pool is used; in this case, we match on bridge name. This is a sensible fall-back option for imports in general.

* All other networks are recreated on the pool. The bridge (xapi0, xapi1, ...) is renamed such that it is unique on the pool. All other network fields are copied from the host's network object.
