[PATCH BlueZ v1 0/5] shared/gatt-db: Add support for client role.

[Arman Uguray <armansito@chromium.org>]

*v1: Addressed comments by Luiz and Michael.

This patch introduces new API functions to shared/gatt-db to prepare it for
GATT client-role usage. This is the first step before rewriting
shared/gatt-client using gatt-db.

This patch set adds the following:
  - Functions for extracting service, characteristic, descriptor, and include
    definition information from appropriate attributes.
  - foreach functions that allows iterating through all services, listing the
    characteristics of a particular service, etc.
  - Database clear functions to remove services from that database as needed.
  - A new service insertion function for inserting a service with a pre-defined
    handle into the database.
  - A new queue_push_after function for shared/queue to enable the previous
    point.

Comments are welcome. I have implemented a trial version of the new gatt-client
using the above additions and this is the basic set of functionality that should
enable most use cases for client role. I think this gives us enough of a
starting point that we can easily change later if we find that these could be
done better.
