[PATCH BlueZ v4 0/5] Add BIP for AVRCP covert art OBEX client

["Frédéric Danis" <frederic.danis@collabora.com>]

If AVRCP Target supports Cover Art download its SDP record contains an
additional access protocol for OBEX with an LCAP PSM on which the OBEX
client session should connect to, with the specific OBEX target header
7163DD54-4A7E-11E2-B47C-0050C2490048.

Once the OBEX session is connected, the AVRCP track metadata will contain
an Image Handle which can be used to get the associated image using
GetImageThumbnail or GetImage with one of the description property found
with GetImageProperties.

This has been tested with iPhone 14, iPhone 15 Pro and Samsung S23.

v1 -> v2: Parse integer properties as integer instead of string
          Return GetImageProperties values as aa{sv} instead of aa{ss}
          Get properties for GetImage as a{sv} instead of a{ss}
          Set new properties and interface as experimental
v2 -> v3: Rename obexd/client/bip-avrcp.[ch] to obexd/client/bip.[ch]
          Update the AVRCP Controller version in SDP to 1.6
          Add commit to support for specific headers in obex transfer
          Fix memory leaks
v3 -> v4: Commits 1-4 has been merged
          Change org.bluez.obex.BipAvrcp1 to org.bluez.obex.Image1
          Change GetImageThumbnail to GetThumbnail
          Change GetImageProperties to Properties
          Change GetImage to Get
          Add possible property values for the description dicts
