as the "where to put the packet data" argument.
This lets more of the libwiretap code be common between the read and
seek-read code paths, and also allows for more flexibility in the "fill
in the data" path - we can expand the buffer as needed in both cases.

implemented wtap_dump_file_seek() and _tell()
implemented the previously declared but unimplemented wtap_dump_file_seek() and wtap_dump_file_tell() functions and used them in the seven files that had previously used a plain ftell or fseek and added error checking as appropriate. I also added a new error WTAP_ERR_CANT_SEEK_COMPRESSED and put it next to WTAP_ERR_CANT_SEEK causing renumbering of two of the existing error codes.

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.

This is POC we may want to have more efficient use of the frame data

Add to wiretap/pcap-common.c a routine to fill in the pseudo-header for

zran.c example in the zlib source.
This means that problems in the file's contents might not be reported
when a packet is read, as long as there's no problem in the contents of
the file up to the last bit of compressed data for the packet; we now
check for errors after finishing the sequential read of the file, at
least in some programs, so that shouldn't be an issue (the other
programs need to be changed to do so as well). This is necessary in
order to be able to read all the packets we saw in the sequential pass;
it also lets us get a few more packets from truncated files in some
cases.

calls that use it, cast it to whatever it's supposed to be. Making it a
gzFile means you can't use any stdio macros that reach inside the
structure; making it a FILE *, as it used to be, amounts to trying to
use a FILE * as a void * if we're writing a compressed file out.

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.
In wiretap file_read() this is not really used, file_read is called
either with bsize set to 1 or count to 1.
Attached patch remove bsize argument from macro.

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.

Have the generic wtap close routine free up the private data, rather

#include winsock2.h pulls in about 90 distinct .h files
and about 140 total .h files.
Currently winsock2.h is (mostly unnecessarily) included
for each dissector via packet.h/wtap.h.
This patch removes #include winsock2.h from wtap.h and
then includes winsock2.h (or windows.h) in the
few specific places required.
With this patch, my Windows Wireshark build takes
about 30% less time.

point, so we don't have issues with numbers not being exactly
representable; that makes it less likely that the change described below
will change a time stamp if it's not fixing the time stamp (i.e., if
time_day is 0).
The Sniffer manual "Expert Sniffer(R) Network Analyzer Operations,
Release 5.50" says that a frame2_rec has a time stamp with an 8-bit
time_high field and an 8-bit time_day field. Interpreting the time
stamp that way fixes the time stamps in at least some captures; see, for
example, bug 2251.
Fix/update some comments (for example, the Sniffer documentation is no
longer at that URL).
