Move the frame_set stuff back into the capture_file structure. 

libwireshark now expects an epan_t to be created with a pointer to a
"packet provider" structure; that structure is opaque within
libwireshark, and a pointer to it is passed to the callbacks that
provide interface names, interface, descriptions, user comments, and
packet time stamps, and that set user comments.  The code that calls
epan_new() is expected to provide those callbacks, and to define the
structure, which can be used by the providers.  If none of the callbacks
need that extra information, the "packet provider" structure can be
null.

Have a "file" packet provider for all the programs that provide packets
from a file.
