Restrict the address range dumped in crash reports.

Add frame dumping capabilities to report generator.

- If the top frame of a stopped thread has no arguments or variables
available, dump the memory block to which the stack frame belongs,
starting at the current stack pointer and extending to the end of
the block.

Remove unnecessary code.

- ResolveValueNodeJob() already handles location resolution for the
NodeChild so this step is unnecessary.

Refactor DebugReportGenerator to use jobs.

- Instead of asking nodes to resolve themselves directly,
DebugReportGenerator now uses the interface listener to ask the
debugger's workers to resolve them on its behalf.

Refactor DebugReportGenerator to use PrintValueNodeGraph.

Print parameters/local variables if available..

- If debug information is present, then for each stack frame we now
also dump all function parameters and local variables and their
respective values, as well as their first level of children if
applicable.

DebugReportGenerator shouldn't inherit from BReferenceable.

Rework control flow for debug report generator.

- DebugReportGenerator is now its own BLooper that generates reports asynchronously
instead of in TeamDebugger's message loop.
- If a stack trace isn't yet available, DebugReportGenerator now waits for it to
be generated.
- Extended Team to add a listener event for report generation completing. DebugReportGenerator
now generates such an event when it has finished writing a report.

Add simple report header.

Minor cleanups.

Add initial version of DebugReportGenerator controller class.

Not yet complete or made use of.
