add WIP "netconsole" KDL add-on

Similar to Linux netconsole, this should send all debug output over UDP
to the broadcast address. It can be listened to with netcat or similar tools.
This could be an easy way to extract KDL info from a crashing machine
when no serial ports are available.

Does not work yet, help welcome.

Add qrencode kernel debugger add-on to the build.

The defines in the Jamfile remap the memory allocation functions to use
debug heap versions of the corresponding functions.

Adding a run_on_exit kernel debugger add-on. It installs a debugger command
"on_exit" with which you can add commands to run when exiting the debugger.
With this you could for example "on_exit sync" and "on_exit shutdown -r" when
your app_server crashed.

* Added simplified possibility to schedule UHCI transfers from within KDL.
* Added debugger commands to resolve usb_ids to pipes.
* Adjusted the physical memory allocator to be usable in a slimmed down mode
when running inside the kernel debugger.
* Implemented USB keyboard support for KDL through a kernel debugger add-on.
* Added kgetc() and made use of it where previously individual methods were used
to ensure that reading characters always goes through the kernel debugger
add-ons and the other methods.

This has some preconditions to meet though:
1) The keyboard must be in the boot protocol (currently the case but needs to
be revisited once we have a full usb_hid).
2) The keyboard must be attached to a UHCI root port (i.e. not use EHCI or OHCI,
also not through hubs unless those are USB 1.1).
3) the usb_hid driver has to be opened for this to work. This means that for the
time between initializing USB and when usb_hid is opened by the input_server
there is no keyboard support.

Also note that this has no way of detecting hot-plug, meaning that you can't
re-attach your USB keyboard from the hub to the root port once in KDL.

On the bright side of things, since this is a non-destructive mechanism it is
possible to enter and leave KDL without loosing the USB state.

Tested OK in QEMU, not tested on real hardware yet, will see in a few minutes.

disasm kernel debugger module providing a dis addr [count] command, currently only for x86, using Udis86.

A module that hooks into the debugger to provide it with a demangle() so at least when using C++ in the kernel stack crawls are meaningful.
It does its job by using part of libsupc++, with fake malloc and friends to make sure it won't double fault.
Works here, but cp-demangle must be extracted by hand from the lib, can't get the rule to work as I want, Ingo ?
Maybe using it directly without malloc hack would be ok with 16KB buffer, but I'm not sure of that.

I really thought that such a small change wouldn't break the build...

git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@24028 a95241bf-73f2-0310-859d-f6bbb57e9c96

* Debugger modules now have two methods: enter_debugger() and exit_debugger().
* The kernel now opens up to 8 debugger modules (and puts them into an array;
maybe we'll want to switch to a doubly linked list when there is the need).
* Implemented an example debugger module that prints a stack trace of the
current thread when the kernel debugger is entered (not included in the
image).
