add versions of CRC-16 and CRC-32 routines with seed arguments;
add versions of those routines with an "offset in the tvbuff"
argument;
add Doxygen comments to the CRC-16 and CRC-32 headers.

they have LF at the end of the line on UN*X and CR/LF on Windows;
hopefully this means that if a CR/LF version is checked in on Windows,
the CRs will be stripped so that they show up only when checked out on
Windows, not on UN*X.

Rename the "crc32.c" CRC-32 routine "crc32_ccitt_tvb()", to match the
"crc16.c" CRC-16 routine, and rename the table it uses to match. Also
rename "crc32_tvb_802" to "crc32_802_tvb", to match "crc32_ccitt_tvb()".

Extract the FCS decoding section of the PPP_HDLC dissector to
allow the CHDLC dissector to use the same routine.
The ppp_options used for preferences has been renamed to
fcs_options and exported via packet-ppp.h so CHDLC gets a
separate (but identical) FCS preference.
This means prefs.h has to be included before packet-ppp.h so a
couple of ppp related files (packet-{gtp,null,raw,vj}.c) had
their includes slightly re-arranged.
From me: make the PPP/CHDLC FCS code use "crc32()" to check the 32-bit
FCS.
