Allow bigger D-Bus packets, but don't allocate big buffers initially.

D-Bus packets can be up to 128MB in size, but don't allocate 128MB for
every pcap_t, or even every D-Bus pcap_t.  Start out with enough to
handle 2KB packets - that should be enough for most regular network
packets - and grow the buffer as necessary to handle packets up to the
snapshot length.

Treat packets bigger than the maximum snapshot length for the link-layer
type as errors; we continue to use MAXIMUM_SNAPLEN (256KB) for most
link-layer header types, but use 128MB for DLT_DBUS, as per the above.

If the snapshot length in the file header or IDB is 0, or is > 2^31-1,
use the maximum snapshot length for the link-layer header type as the
snapshot length.  The check for 2^31-1 is there because the current API
for snapshot lengths returns an int, and thus can't handle snapshot
lengths > 2^31-1, even though the field is actually unsigned.
