[pve-devel] [PATCH v4 many] Add container device passthrough

[Filip Schauer]

Changes since v1:
* mknod the devices in /var/lib/lxc/$vmid/passthrough and setup proper
  permissions instead of bind mounting the devices from /dev directly
* Add support for USB mapping
* Add foreach_passthrough_device helper function

Changes since v2:
* Remove support for USB mapping
* Add mknod syscall
* Setup a tmpfs to mknod the devices to instead of writing to the host
  file system
* Write passthrough dev list to /var/lib/lxc/$vmid/passthrough_devices
* Move sub foreach_passthrough_device out of the AbstractConfig into the
  container config
* Add mode, uid and gid properties to passthrough device config

Changes since v3:
* Allow only root user to configure device passthrough
* Verify format of device passthrough mode
* Add mount flag constants
* Remove redundant error checks
* Add missing error checks
* Optimize file creation by using mknod instead of touch
* Correctly handle id mapping with multiple ranges
