Greg Clayton 0603aa9dc8 There are now to new "settings set" variables that live in each debugger 
instance:

settings set frame-format <string>
settings set thread-format <string>

This allows users to control the information that is seen when dumping
threads and frames. The default values are set such that they do what they
used to do prior to changing over the the user defined formats.

This allows users with terminals that can display color to make different
items different colors using the escape control codes. A few alias examples
that will colorize your thread and frame prompts are:

settings set frame-format 'frame #${frame.index}: \033[0;33m${frame.pc}\033[0m{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{ \033[0;35mat \033[1;35m${line.file.basename}:${line.number}}\033[0m\n'

settings set thread-format 'thread #${thread.index}: \033[1;33mtid\033[0;33m = ${thread.id}\033[0m{, \033[0;33m${frame.pc}\033[0m}{ \033[1;4;36m${module.file.basename}\033[0;36m ${function.name}{${function.pc-offset}}\033[0m}{, \033[1;35mstop reason\033[0;35m = ${thread.stop-reason}\033[0m}{, \033[1;36mname = \033[0;36m${thread.name}\033[0m}{, \033[1;32mqueue = \033[0;32m${thread.queue}}\033[0m\n'

A quick web search for "colorize terminal output" should allow you to see what
you can do to make your output look like you want it.

The "settings set" commands above can of course be added to your ~/.lldbinit
file for permanent use.

Changed the pure virtual 
    void ExecutionContextScope::Calculate (ExecutionContext&);
To:
    void ExecutionContextScope::CalculateExecutionContext (ExecutionContext&);
    
I did this because this is a class that anything in the execution context
heirarchy inherits from and "target->Calculate (exe_ctx)" didn't always tell
you what it was really trying to do unless you look at the parameter.
