We add them when configuring with autotools, so that we build GLib
appropriately for the OS versions we're targeting; do the same when
configuring with Meson.
If this version of macOS comes with a version of libffi, generate a .pc
file for it and install it in /usr/local/lib/pkgconfig, so that
pkg-config finds that version of libffi, and the GLib configuration
process - whether it's done with autotools or Meson - doesn't decide
that there is no libffi and fail or install its own libffi or whatever.
1. New EtherNet/IP commands and Common Packet Formats
2. CIP Security: Attributes (These go better in enip vs cip dissector)
3. TCP/IP object: Improve existing attribute parsing
4. Certificate Management Object: Attribute
5. Add units for some existing types
6. Correct hf_ size mismatch
If we're running an external Python 3 package, pip3 will install scripts
in some directory under /Library; set MESON to point to the location
where Meson will be installed, and use that.
Have a meson-done file to indicate that Meson's been installed by us,
and uninstall it only if that's present.
We want to check whether *Apple* provides Python 3, not whether there's
a Python 3 installed; if there is no Apple-provided Python 3, but
there's somebody else's Python 3 installed, leave it alone, don't
uninstall it.
Newer versions of GLib require Meson (they don't support autotools) and
Ninja (they use Ninja rather than Make). Install Meson and, based on
the GLib version, use autotools+make or Meson+Ninja to build GLib.
Move up the installation of Python 3 so that it's available when we
install Meson, as Meson requires Python 3 and is installed with pip3.
Only install an external Python 3 if /usr/bin/python3 doesn't work; on
at least some versions of macOS, /usr/bin/python3 is a wrapper to run
Python 3 from Xcode, and at least some versions of Xcode provide Python
3.
This utility function is useful outside of epan. Move it to wsutil
and export the interface.
The move isn't completely clean as it requires duplicating two small
inline functions but that was necessary to avoiding moving too much at
once.
As requested [here][1], help with replacing calls to
`wmem_packet_scope()` with references to `pinfo->pool`.
My principles were:
* Plugins chosen semi-randomly.
* When a calling function already has a `pinfo` argument, just use that.
* Remove `_U_` from its signature if it was there.
* Don't go more than 2 or 3 levels deep of changing signatures.
* If a function is clearly allocing memory to return, change the
function signature to take a `wmem_allocator_t *`. Otherwise, either
that or take a `packet_info *` as seems to make sense.
* No mention of `wmem_packet_scope()` should remain in the files I've
touched.
* I didn't always succeed at this, but I made a dent.

1. Connection Manager parameter is called 'Redundant Owner' instead of 'Exclusive'
2. Add new CIP Class Names
3. Support new time types: UTIME, STIME, NTIME
4. Add units to data type
This significantly reduces boilerplate required for adding fields.
The changes to SMSG_CHAR_CREATE from ENC_LITTLE_ENDIAN to ENC_NA are
intentional, as are the changes to CMSG_CHAR_RENAME from realm_name to
character_name.
