This reverts commit c0c480d08c.
A better way to do this is to have the record type be part of struct wtap_pkthdr; that keeps the metadata for the record together and requires fewer API changes. That is in-progress.

This is the first step towards implementing the mechanisms requestd in
bug 8590; currently, we don't return any records other than packet
records from libwiretap, and just ignore non-packet records in the rest
of Wireshark, but this at least gets the ball rolling.

Start of refactoring Wiretap and breaking structures down into "generally useful fields for dissection" and "capture specific". Since this in intended as a "base" for Wiretap and Filetap, the "wft" prefix is used for "common" functionality.
The "architectural" changes can be found in cfile.h, wtap.h, wtap-int.h and (new file) wftap-int.h. Most of the other (painstaking) changes were really just the result of compiling those new architecture changes.

wtap_file_read_expected_bytes() from an open routine - open routines are
supposed to return -1 on error, 0 if the file doesn't appear to be a
file of the specified type, or 1 if the file does appear to be a file of
the specified type, but those macros will cause the caller to return
FALSE on errors (so that, even if there's an I/O error, it reports "the
file isn't a file of the specified type" rather than "we got an error
trying to read the file").
When doing reads in an open routine before we've concluded that the file
is probably of the right type, return 0, rather than -1, if we get
WTAP_ERR_SHORT_READ - if we don't have enough data to check whether a
file is of a given type, we should keep trying other types, not give up.
For reads done *after* we've concluded the file is probably of the right
type, if a read doesn't return the number of bytes we asked for, but
returns an error of 0, return WTAP_ERR_SHORT_READ - the file is
apparently cut short.
For NetMon and NetXRay/Windows Sniffer files, use a #define for the
magic number size, and use that for both magic numbers.

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.

by Wiretap, to indicate whether certain fields in that structure
actually have data in them.
Use the "time stamp present" flag to omit showing time stamp information
for packets (and "packets") that don't have time stamps; don't bother
working very hard to "fake" a time stamp for data files.
Use the "interface ID present" flag to omit the interface ID for packets
that don't have an interface ID.
We don't use the "captured length, separate from packet length, present"
flag to omit the captured length; that flag might be present but equal
to the packet length, and if you want to know if a packet was cut short
by a snapshot length, comparing the values would be the way to do that.
More work is needed to have wiretap/pcapng.c properly report the flags,
e.g. reporting no time stamp being present for a Simple Packet Block.

Use it for some file header problems for which it wasn't already being

file_read(buf, bsize, count, file) macro is compilant with fread
function and takes elements count+ size of each element, however to make
it compilant with gzread() it always returns number of bytes.

either with bsize set to 1 or count to 1.

Don't assume pinfo->p2p_dir is either P2P_DIR_SENT or P2P_DIR_RECV when
setting the info column in various Bluetooth dissectors; it might be
unknown.
In the HCI H4 dissector, put the direction into the info column
regardless of whether we have a type match or not; the dissectors for
HCI packet types appear to assume it's been set (as they put a blank at
the beginning of the stuff they append to the direction).

everybody use it; the places using the old wtap_dump_file_write() were
using it in the same way the old wtap_dump_file_write_all() did.
That also lets us get rid of wtap_dump_file_ferror().
Also, have the new wtap_dump_file_write() check for errors from
gzwrite() and fwrite() differently - the former returns 0 on error, the
latter can return a short write on error.

svn path=/trunk/; revision=25580
Added support for Symbian OS btsnoop.
The bluetooth HCI layer in Symbian OS can be configured to log all packets to a
file. The log format, "btsnoop" is based on the RFC1761 "snoop" format - but
differences in the header make it incompatible.
The btsnoop format supports logging of these formats:
"H1" (raw HCI packets without framing)
"H4" (HCI UART packets including packet type header)
"H5" (HCI 3 wire UART packets including framing)
"BCSP" (HCI bluecore serial protocol including framing)
"H1" and "H4" are section numbers in the original v1 bluetooth specifications,
but still used colloquially - wireshark's existing support for Linux bluez HCI
logs uses the "H4" name.
In practice, the "H1" format is used for H5,BCSP and USB HCI logs, as the HCI
packet logs are mainly useful for debugging higher layers, bluetooth profiles
and bluetooth applications.
From me:
Deleted some unused prototypes.
Mark an unused parameter.
