[lldb-dev] logging in lldb

[Pavel Labath via lldb-dev]

Ah, I totally forgot about the llvm DEBUG macro. I would be open to
trying merge these two approaches together. However, I think our's is
a much more heavy-weight system, so it might be too heavy for llvm,
and I am not sure how much would we be willing to lose in the process:
- we have two level logging architecture ("process" category in "lldb" channel)
- logging can be enabled/disabled at runtime
- logs can be redirected to various destinations

Maybe it will be possible to design it in a way that the complexity is
apparent to those who wish to use it. I'll need to think about that...
