These conflicts were mostly related to autostyle improvements, with
one or two due to doxygen fixes.
In case of error, a negative value will be returned or NULL written into
first supplied argument.
This patch uses both cases to comply with style in the specific files.
A tor_vasprintf error in process_vprintf would lead to a NULL dereference
later on in buf_add, because the return value -1 casted to size_t would
pass an assertion check inside of buf_add.
On the other hand, common systems will fail on such an operation, so it
is not a huge difference to a simple assertion. Yet it is better to
properly fail instead of relying on such behaviour on all systems.

Split the core reply formatting code out of control_fmt.c into
control_proto.c. The remaining code in control_format.c deals with
specific subsystems and will eventually move to join those subsystems.
