(otherwise, nobody sees them); do so.
Fix some cases where we weren't doing the proper post-processing after
doing the heuristics for format changes that didn't involve magic-number
changes (discovered because constructing the interface list is now being
done as part of that post-processing).
Fixes bug 7287.

(read a record header) from failure (got an EOF or an error). Make it
just return a Boolean.
If it fails in vwr_read(), don't overwrite *err_info (yes,
vwr_read_rec_header() might have set *err_info, so don't lose - and
leak! - the value it returned) - trust vwr_read_rec_header(), or the
routines it calls, to have set it. (If there's a code path where that
doesn't happen, that code path needs to be fixed; the setting of
*err_info in vwr_read() should *not* be restored.)
Thanks to Evan Huus for finding a useless variable with cppcheck, and
reporting it in bug 7295, provoking me to look at this.

the default extension for the file type iff
the file type we're using has a list of extensions;
the file has no extension or it has one but it's not one of the
ones in the list.
*Don't* expect a file extension to be at most 5 characters plus the dot
- the extension for pcap-ng, our default capture file type, is "pcapng",
and that's 6 characters!

which could use lseek() and were thus expensive due to system call
overhead. To avoid making a system call for every packet on a
sequential read, we maintained a data_offset field in the wtap structure
for sequential reads.
It's now a routine that just returns information from the FILE_T data
structure, so it's cheap. Use it, rather than maintaining the data_offset
field.
Readers for some file formats need to maintain file offset themselves;
have them do so in their private data structures.

we know we had a real problem with the file. If we just get a short
read, return 0, as it means the file is probably not a VWR file.
If we get an invalid message length when reading packets (rather than
when looking for the FPGA version), return WTAP_ERR_BAD_FILE and an
"Invalid message record length" indication, not a generic fallback
"can't read the file" error.
For file_tell() errors, fetch the error code with file_error().
For file_seek() errors, use the error file_seek returned.

We might want to add a SHB comment from mergecap giving the merged filenames or something like that, Merging of pcapng files

1. A VWR encapsulation that reads VeriWave capture files (*.vwr)
generated from
WaveTest test hardware
2. Dissectors that display the VeriWave tap headers (both 802.11 and
Ethernet)
3. A dissector for the WaveAgent protocol. The WaveAgent dissector is
heuristic and parses the WaveAgent packet (a UDP payload).
The WaveAgent dissector has been Fuzz tested.
The VWR ENCAP and dissectors have been used extensively by VeriWave
customers in a special version of WireSark compiled by VeriWave.

Unable to display the correct IEEE802.11 MCS data rates due to header definition
The problem is due to the ieee_802_11_phdr.data_rate is defined as guint8,
since this variable is counting number of 0.5Mbps units, any datarates which is
higher than 255Mbps would get wrapped up. In the above example, only the lower
8bit value will be put into the ieee_802_11_phdr which is 0x04 and result in
the incorrect 2Mbps display.
There are 802.11n WLAN product is capable to transmit @450Mbps, we should fix
this data_rate from guint8 to guint16.

Add a new WTAP_ENCAP_BACNET_MS_TP_WITH_PHDR encapsulation type, for use
by the EyeSDN file reader; unlike the pcap-encapsulated MS/TP, it
includes a direction indicator. Don't treat WTAP_ENCAP_BACNET_MS_TP as
if it has a direction indicator, as it doesn't; instead, do that for
WTAP_ENCAP_BACNET_MS_TP_WITH_PHDR.
Add some missing entries to encap_table_base for WTAP_ENCAP_ values that
didn't get entries added.

The attached patch extends the mpeg2 ts format detection to take into account
that trailing bytes might be added to each packet.
Once it finds no sync after 188 bytes, it checks an additional 40 bytes for the
next sync byte and adjusts the packet size accordingly.
Only the 188 bytes of the actual ts packet are passed on to wiretap, the
trailer is omitted.
