o build-swig-Python.sh should also checks the timestamp of ${swig_input_file}
  for update eligibility.  Also, once an update is in order, there's no need
  to check the remaining header files for timestamps.

o Coaches swig to treat StopReason as an int type, instead of a C++ class.

code stepping. Also we now store the stack frames for the current and previous
stops in the thread in std::auto_ptr objects. When we create a thread stack
frame list we pass the previous frame into it so it can re-use the frames
and maintain will allow for variable changes to be detected. I will implement
the stack frame reuse next.

Added invoke() method to TestBase to factor in the tracing logic in one place.
This method allows an object to call a method with no arg reflectively.

has inlined functions that all started at the same address, then the inlined
backtrace would not produce correct stack frames.

Also cleaned up and inlined a lot of stuff in lldb_private::Address.

Added a function to StackFrame to detect if the frame is a concrete frame so
we can detect the difference between actual frames and inlined frames.

complex inlined examples.

StackFrame classes don't have a "GetPC" anymore, they have "GetFrameCodeAddress()".
This is because inlined frames will have a PC value that is the same as the 
concrete frame that owns the inlined frame, yet the code locations for the
frame can be different. We also need to be able to get the real PC value for
a given frame so that variables evaluate correctly. To get the actual PC
value for a frame you can use:

    addr_t pc = frame->GetRegisterContext()->GetPC();

Some issues with the StackFrame stomping on its own symbol context were 
resolved which were causing the information to change for a frame when the
stack ID was calculated. Also the StackFrame will now correctly store the
symbol context resolve flags for any extra bits of information that were 
looked up (if you ask for a block only and you find one, you will alwasy have
the compile unit and function).

which is now on by default. Frames are gotten from the unwinder as concrete
frames, then if inline frames are to be shown, extra information to track
and reconstruct these frames is cached with each Thread and exanded as needed.

I added an inline height as part of the lldb_private::StackID class, the class
that helps us uniquely identify stack frames. This allows for two frames to
shared the same call frame address, yet differ only in inline height.

Fixed setting breakpoint by address to not require addresses to resolve.

Each inline frame contains only the variables that they contain and each inlined
stack frame is treated as a single entity.

which, defaults to False, and if set to True, will trace lldb command execution

Added "-t" command option to the test driver dotest.py which sets the
LLDB_COMMAND_TRACE environment variable to "YES" and as a result always turns on

to spawn a thread for each process that is being monitored. Previously
LLDB would spawn a single thread that would wait for any child process which
isn't ok to do as a shared library (LLDB.framework on Mac OSX, or lldb.so on
linux). The old single thread used to call wait4() with a pid of -1 which 
could cause it to reap child processes that it shouldn't have.

Re-wrote the way Function blocks are handles. Previously I attempted to keep
all blocks in a single memory allocation (in a std::vector). This made the
code somewhat efficient, but hard to work with. I got rid of the old BlockList
class, and went to a straight parent with children relationship. This new 
approach will allow for partial parsing of the blocks within a function.
