New pcap helpers

This was sent to the ML on 31/8, but went unnoticed, so I post it as a wishlist
bug. I've also just read that ns-3 is on maintenance phase, but I'd like to ask
its inclusion to be considered.

-------------

For a project I'm working on, I need to set up pcap tracing while
being able to define exactly which filename the traces will have. Now,
the helper methods unconditionally append the node and device ids and
the ".pcap" suffix. I've created a patch that defines a new method
EnablePcapExplicit with exactly the same arguments as EnablePcap, but
doesn't append anything to the filename argument. ATM, I'd just
implemented overloaded methods for the nodeid+deviceid and device ptr
versions, but if you think it's worthwhile, I can add equivalent
methods for the other signatures of EnablePcap.

I've also included the updated bindings for this.

I'd like to ask you to consider merging this functionality. Maybe
you'd prefer a different method name, or some different organisation.
What I'd like to avoid is any diversion from the ns-3-dev main tree.

Thanks, Martín.

PS: please note that the current revision of ns-3-dev has some of the
bindings out of sync. When I run --python-scan, these files are
modified:
M bindings/python/ns3_module_core.py
M bindings/python/ns3_module_internet_stack.py
M bindings/python/ns3_module_wifi.py
