The driver vtables are read-only structures. This patch declares them as
'const' allowing the compiler to (optionally) put them in the RELRO
section. RELRO pages may be marked as read-only by the linker after
the relocations have been done ensuring that they aren't inadvertently
or maliciously altered at runtime.
The Calypso voice call driver uses an ofono_call object that is on the
stack. It is not automatically initilized to zero and thus causes to
have a name presentation that is not valid UTF-8. This in return makes
D-Bus fail and disconnect from the bus.
To fix this ensure that the ofono_call object is properly set to zero
first before populating it with values.

This seems to make the calypso return from ATD right away instead of
waiting for connect/busy to be returned. It should now be possible to
hangup alerting calls.
