Guy Harris 937ec02581 1514 is a better initial Buffer size than 1500.
Ethernet packets without the CRC are 1514 bytes long, not 1500 bytes
long; using 1514 bytes will avoid a reallocation for a full-sized
Ethernet packet.

Peter Wu 31aba351e2 wiretap: fix memleaks with wtap_rec::opt_comment
The memory ownership of wtap_rec::opt_comment was not clear. Users of
wtap were leaking memory (editcap.c). wtap readers were not sure about
freeing old comments (erf) or simply ignored memleaks (pcapng).

To fix this, ensure opt_comment is owned by wtap_rec and free it with
wtap_rec_cleanup. The erf issue was already addressed since
cf_get_packet_comment properly duplicates wth.opt_comment memory.

- wtap file formats (readers):
  - Should allocate memory for new comments.
  - Should free a comment from an earlier read before writing a new one.
- Users of wth:
  - Can only assume that opt_comment remains valid until the next read.
  - Can assume that wtap_dump does not modify the comment.
  - For random access (wtap_seek_read): should call wtap_rec_cleanup
    to free the comment.

The test_tshark_z_expert_comment and test_text2pcap_sip_pcapng tests now
pass when built with ASAN.

This change was created by carefully looking at all users opt
"opt_comment" and cf_get_packet_comment. Thanks to Vasil Velichkov for
an initial patch which helped validating this version.

Peter Wu e2e5b01d77 cli_main: remove real_main from stack traces for non-Windows
Restore the "main" name since that is used everywhere else except for
Windows. On Windows, "main" is renamed via a macro to avoid a conflict
with "wmain" and to allow it to be called in cli_main.c.

For those wondering, GUI applications (such as Qt) have a different
entry point, namely WinMain. In Qt5, src/winmain/qtmain_win.cpp defines
WinMain, but seems to convert its arguments from Unicode to CP_ACP
(ASCII). It might not support UTF-8, but I did not verify this.

Guy Harris a34cc98b2a Put the main() and wmain() routines for CLI programs into a separate file.
That means that code is only in one place, rather than having copies of
it in each of those programs.

CLI programs that, on Windows, should get UTF-8 arguments rather than
arguments in the local code page should:

	include the top-level cli_main.h header;

	define the main function as real_main();

	be built with the top-level cli_main.c file.

On UN*X, cli_main.c has a main() program, and just passes the arguments
on to real_main().

On Windows, cli_main.c has a wmain() function that converts the UTF-16
arguments it's handed to UTF-8 arguments, using WideCharToMultiByte() so
that it doesn't use any functions other than those provided by the
system, and then calls real_main() with the argument count and UTF-8
arguments.

(with lack of dynamic content the documentation can only refer

Guy Harris a1372f6d01 Use an enum for compression types in various interfaces.
This:

1) means that we don't have to flag the compression argument with a
comment to indicate what it means (FALSE doesn't obviously say "not
compressed", WTAP_UNCOMPRESSED does);

2) leaves space in the interfaces in question for additional compression
types.

(No, this is not part 1 of an implementation of additional compression
types, it's just an API cleanup.  Implementing additional compression
types involves significant work in libwiretap, as well as UI changes to
replace "compress the file" checkboxes with something to indicate *how*
to compress the file, or to always use some other form of compression).

three parameters for the SHB, IDB and NRB blocks that has to be written
before packets are even written. Similarly, a lot of tools always create

Address the former duplication by creating a new data structure to hold
the arguments. Address the second issue by creating new helper functions
to initialize the parameters based on a wth. This refactoring should
make it easier to add the new Decryption Secrets Block (DSB).

Guy Harris a679ae6f79 Use wsetargv.obj, and wmain() rather than main(), on Windows.
Doing so for command-line programs means that the argument list doesn't
ever get converted to the local code page; converting to the local code
page can mangle file names that *can't* be converted to the local code
page.

Furthermore, code that uses setargv.obj rather than wsetargv.obj has
issues in some versions of Windows 10; see bug 15151.

That means that converting the argument list to UTF-8 is a bit simpler -
we don't need to call GetCommandLineW() or CommandLineToArgvW(), we just
loop over the UTF-16LE argument strings in argv[].

While we're at it, note in Wireshark's main() why we discard argv on
Windows (Qt does the same "convert-to-the-local-code-page" stuff); that
means we *do* need to call GetCommandLineW() and CommandLineToArgvW() in
main() (i.e., we duplicate what Qt's WinMain() does, but converting to
UTF-8 rather than to the local code page).

Guy Harris e7d24c606c Always explicitly set tm_isdst before calling mktime().
Except in rare cases, we want to set it to -1 so that we let mktime()
determine whether DST/Summer Time was in effect at the given date and
time rather than pretending that we know whether it's in effect or not.

Guy Harris 1f5f63f8ef Generalize wtap_pkthdr into a structure for packet and non-packet records.
Separate the stuff that any record could have from the stuff that only
particular record types have; put the latter into a union, and put all
that into a wtap_rec structure.

Add some record-type checks as necessary.

Guy Harris b0c0490fe0 Don't overwrite the struct wtap_pkthdr; copy and change it instead.
Do as we do in other cases - copy the current struct wtap_pkthdr to a
temporary one (which might copy the temporary one to itself), modify it,
and set the pointer to the struct wtap_pkthdr to point to the temporary
one.

Note all the places wherw we do this with a comment.

g995812c5f1 moved wiretap plugins registration from applications to
wiretap library init function.
As we do not want to load plugins for all users of libwiretap, let's
make it configurable.

João Valverde 995812c5f1 Refactor plugin registration and loading
Put different types of plugins (libwiretap, libwireshark) in different
subdirectories, give libwiretap and libwireshark init routines that
load the plugins, and have them scan the appropriate subdirectories
so that we don't even *try* to, for example, load libwireshark plugins
in programs that only use libwiretap.

Compiled plugins are stored in subfolders of the plugin folders, with
the subfolder name being the Wireshark minor version number (X.Y). There is
another hierarchical level for each Wireshark library (libwireshark, libwscodecs
and libwiretap).

The folder names are respectively plugins/X.Y/{epan,codecs,wiretap}.

Currently we only distribute "epan" (libwireshark) plugins.

A while back Graham pointed out the SPDX project (spdx.org), which is
working on standardizing license specifications:

https://www.wireshark.org/lists/wireshark-dev/201509/msg00119.html

Appendix V of the specification describes a short identifier
(SPDX-License-Identifier) that you can use in place of boilerplate in
your source files:
