[PATCH obexd v0 2/6] client: Split internal obc_transfer_register()

[Mikel Astiz <mikel.astiz.oss@gmail.com>]

From: Mikel Astiz <mikel.astiz@bmw-carit.de>

The creation process has been internally split into two steps: creation
and D-Bus registration. This is easier to understand and it also allows
to expose these two-steps in the transfer API.
