Add the ability to perform a write on the object name GATT
Characteristic with a notification callback to the application
that the name has been written.
In order for this operation to work the memory backing the
object name must be modifiable. To prevent forcing the user
to always allocate 120 bytes for the name, the maximum name
length is changed from a define to a configuration parameter.

Adds name length checks. The OTS spec does not
explicitely specifiy a maximum name length, but the
maximum name length in the directory listing object
shall be less or equal to 120 octets.

Do not make the first object added to the object transfer server the
current (=selected object). This leads to the server having no
current object until one is selected by the client.
This solves a startup issue where the selected callback is not called
by the server if the first object selected by the client happens to be
the same object as the object that was first added to the server. In
that case, the user of the OTS does not know which object is selected,
and therefore may not be able to supply the correct data later.

The directory listing object is an internal object which
content is the aggregation of all the metadata of all objects
(including the directory listing object itself). The client
can read this value to get a list of all objects with names,
lengths, and other metadata.
