[Xen-devel] [PATCH v3 00/11] libxl: add PV display device driver interface

[Oleksandr Grytsov <al1img@xxxxxxxxx>]

From: Oleksandr Grytsov <oleksandr_grytsov@xxxxxxxx>

These patches add PV display device to libxl and xl. To avoid code
duplication the device handling framework was extended with following
callbacks:
 * set_default - initializes libxl_device_xxxx structure with default values;
 * to_device - converts libxl_device_xxxx to libxl__device;
 * init - initializes libxl_device_xxxx structure;
 * copy - copies libxl_device_xxxx to another libxl_device_xxxx;
 * from_xenstore - sets libxl_device_xxxx by xen store settings;
 * set_xenstore_config - sets xen store device config.

Also following generic functions (based on device type) are added:
 * libxl__device_add - adds PV device;
 * libxl__device_list - returns list of existing devices;
 * libxl__device_list_free - frees list of devices.

Changes since v2:
 * devide into small patches;
 * add commit messages
