Subject: [BlueZ v8 00/10] Implement LE Advertisement D-Bus API

Implementation of the LE Advertisement D-Bus API.

Things that are missing still:
* Semantics for multiple Advertisements (currently any more than one will fail)
* TX Power property parsing / interface
* Setting other Flags in the advertisement.

v1 -> v2:
* Cleanup based on comments from Arman
* Add g_dbus_proxy_set_read_watch function to avoid ObjectManager dependency
* Consolidate script updates into single test script

v2 -> v3:
* Change "ManufacturerSpecificData" to "ManufacturerData"
* Add advertisement-api.txt to EXTRA_DIST
* Add Release() callback to org.bluez.LEAdvertisement1
* Remove IncludePower from the LEAdvertisement1 API

v3 -> v4:
* Rename "g_dbus_proxy_set_read_watch" to "g_dbus_proxy_set_ready_watch"

v4 -> v5:
* Rebase
* Use g_dbus_client_set_proxy_handlers instead of g_dbus_proxy_set_ready_watch
* Add MGMT interface calls to actually advertise.

v5 -> v6:
* Minor patch cruft cleanup
* Rename btd_advertising_manager to btd_advertising and fix filename change.

v6 -> v7:
* Rebase for included patches
* Rename ad structure to bt_ad
* Fixes for bt_ad_generate bugs
* Correctly error for invalid length
* Improvements so advertisement-example works out of the box

v7 -> v8:
* Rebase
* Use eir.h constants instead of local constants
* Rename internal structures for brevity
* Add null checks
* Check for queue_* failures
* Address misc other comments

Subject: [BlueZ v8 10/10] test: improvements to advertising-example

Improves the advertising-example in two ways:

It uses 16-bit service UUIDs so that it does not overflow the
Advertisement Data

It turns the adapter's power on so that it works out of the box.
