This allows taps that can fail to report an error and fail; a failed
tap's packet routine won't be called again, so they don't have to keep
track of whether they've failed themselves.
We make the return value from the packet routine an enum.
Don't have a separate type for the per-packet routine for "follow" taps;
they're expected to act like tap packet routines, so just use the type
for tap packet routines.
One tap packet routine returned -1; that's not a valid return value, and
wasn't one before this change (the return value was a boolean), so
presume the intent was "don't redraw".
Another tap routine's early return, without doing any work, returned
TRUE; this is presumably an error (no work done, no need to redraw), so
presumably it should be "don't redraw".
Clean up some white space while we're at it.

Make the time stamp precision a 4-bit bitfield, so, when combined with
the other bitfields, we have 32 bits. That means we put the flags at
the same structure level as the time stamp precision, so they can be
combined; that gets rid of an extra "flags." for references to the flags.
Put the two pointers next to each other, and after a multiple of 8 bytes
worth of other fields, so that there's no padding before or between them.
It's still not down to 64 bytes, which is the next lower power of 2, so
there's more work to do.

"output_rrpd" is NULL when the TRANSUM dissector is disabled (which is
the default behavior). When switching to a profile where the dissector
is enabled, redissection happens, but without invoking the init routine.
This leads to a crash when dissect_transum tries to query "output_rrpd".
Fix this by creating the map unconditionally. Use wmem_map_new_autoreset
since its contents should be erased for new capture files.
