Make dc_parser_new() pass in the serial number to +dc_parser_new_internal

Browse Source 
The libdivecomputer serial number handling is very very messy.

There are multiple issues that make it messy:

 - it's not actually figured out at parse-time, it's figured out at
   download time and passed up through the DC_EVENT_DEVINFO as part of
   the devinfo structure.

 - it's passed around as an "unsigned in" in the devinfo structure,
   which is entirely useless to anybody but libdivecomputer, since a
   serial number isn't actually a number, but a string, and the format
   of the string depends on the dive computer.

 - it is *not* passed to the parser, so the parser can't do a better job
   at it later.

But it turns out that the sane "create new parser" helper function does
actually get it, as part of the "devinfo" that is passed to it.  So as
long as you use that sane interface, we can now pass it in to the actual
parser creation, and then the dive computer parsers that want to do a
reasonable job of actually generating a real serial number string can
now save it off and do so.

This just adds the infrastructure to make this possible.  I'll do the
dive computers one by one.
