Review request for kdelibs.


Changes
-------

Added media-player-info check to CMakeLists; cleaned up xgdbasers; packager info in commit msg and CCMAIL to kde-packager at kde.org (hope it can be sent there from commit hook)

This patch is still based on KDE/4.7 branch (I test it in KDE 4.7), should I port it to frameworks branch? (solid seems moved around in this branch).

udev PortableMediaPlayer: read protocols from media-player-info


Description (updated)

udev PortableMediaPlayer: read protocols from media-player-info

This is a second attempt at implementing PortableMediaPlayer for udev
back-end using media-player-info [3], the first attempt was [2] by
Alex Merry and this patch is heavily based on it. This patch relates to
a discussion at [1] and is just a first step, the second would
be to forward PMP interface from udev backed to udisks backed somehow
(udisks...Device interface provides NativePath attribute that links to
sysfs path that can help - on Linux)

[2] https://svn.reviewboard.kde.org/r/5853/
[3] http://www.freedesktop.org/wiki/Software/media-player-info

Care is taken not to change existing behaviour - e.g. when udev env
ID_MEDIA_PLAYER equals 1, behaviour is unchanged.

PACKAGERS, solid udev backend now has following optional runtime-only
dependency that provides udev rules and other info for identification
of the portable media players:
 * media-player-info: for identifying USB storage devices and iPods

Following packages also provide relevant udev rules, but we suggest not
depending on them as they should by pulled by packages that actually
use them (such as Amarok, transitively):
 * usbmuxd: for identifying iOS-based iPods
 * libmtp >= 1.0.4: for identifying MTP players

Testing
-------

1. connect iPod
2. works:
$ solid-hardware details /org/kde/solid/udev/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/host6/target6:0:0/6:0:0:0/block/sdc
udi = '/org/kde/solid/udev/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/host6/target6:0:0/6:0:0:0/block/sdc'
  parent = '/org/kde/solid/udev'  (string)
  vendor = 'Apple'  (string)
  product = 'iPod'  (string)
  description = 'Portable Media Player'  (string)
  Block.major = 8  (0x8)  (int)
  Block.minor = 32  (0x20)  (int)
  Block.device = '/dev/sdc'  (string)
  PortableMediaPlayer.supportedProtocols = {'storage', 'ipod'}  (string list)
  PortableMediaPlayer.supportedDrivers = {'usb'}  (string list)

3. not yet:

  Block.major = 8  (0x8)  (int)
  Block.minor = 33  (0x21)  (int)
  Block.device = '/dev/sdc1'  (string)
  StorageAccess.accessible = true  (bool)
  StorageAccess.filePath = '/media/MATOUSUV IP'  (string)
  StorageAccess.ignored = false  (bool)
  StorageVolume.ignored = false  (bool)
  StorageVolume.usage = 'FileSystem'  (0x2)  (enum)
  StorageVolume.fsType = 'vfat'  (string)
  StorageVolume.label = 'MATOUSUV IP'  (string)
  StorageVolume.uuid = '3141-5926'  (string)
  StorageVolume.size = 7888957440  (0x1d637f000)  (qulonglong)
