This system allows the kernel debugger to be scripted with the new js command. Functions for reading and writing memory, as well as reading the module list, the registry, and the trap frame registers are provided. A simple mechanism is provided for reading javascript initialization from the registry so that the user may provide custom functions for use during debugging sessions. I have already used it to find a bug in kdb itself; as well as to list sections in modules and perform various other tedious tasks often required while debugging linked lists, etc. This is a static library that will be built when KDBG=1, and linked with ntoskrnl. svn path=/trunk/; revision=7554
