doesn't do safe saves, so wtap_fdreopen() always needs to reopen the
random file descriptor.
At the point where a safe save is done, the sequential read is done, so
the sequential stream is closed; there's no need to reopen it.
(The former fourth argument to wtap_fdreopen() wasn't an indication of
whether the file was compressed, it was an indicationof whether the
random stream should be reopened.)

file that we ourselves have open. In the "safe save" code path for
capture files, on Windows temporarily close the file descriptors for the
currently-open capture before doing the rename and then, if the rename
failed, reopen them, leaving the rest of the wtap and capture_file
structures intact.
Rename filed_open() to file_fdopen(), to make its name match what it
does a bit better (it's an fdopen()-style routine, i.e. do the
equivalent of an open with an already-open file descriptor rather than a
pathname, in the file_wrappers.c set of routines).
Remove the file_ routines from the .def file for Wiretap - they should
only be called by code inside Wiretap.
Closing a descriptor open for input has no reason to fail (closing a
descriptor open for *writing* could fail if the file is on a server and
dirty pages are pushed asynchronously to the server and synchronously on
a close), so just have file_close() return void.

(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
