Remove some single-SHB assumptions. 

Make wtap_file_get_shb() take a section number argument, and update code
that called it.  In most cases, we convert the code to iterate over
sections; in cases where a big code change would be required, we
temporarily pass it 0 and mark the code as "needs to be updated for
multiple sections".

Eliminate cf_read_section_comment(); in calls outside file.c, other code
directly calls the libwiretap routines it calls and, inside file.c, we
just transplant the code and then fix it not to assume a single SHB.
