Cleanup: Move *_loc formatting functions into new format.cpp file

Browse source 
qthelper.cpp is already quite voluminous. Move the recently
introduced localized versions of (v)snprintf() and put_format()
into their own translation unit.

Moreover, adopt C-style semantics for asprintf_loc(). This function
will be used to remove fixed-size buffers in core/plannernotes.c.
