fixed them. Added DISALLOW_COPY_AND_ASSIGN to classes that should
not be bitwise copied. Added default initializers for member
variables that weren't being initialized in the ctor. Fixed a few
shadowed local variable mistakes.

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.
A quick example:
% cat main.cpp
% ./build/Debug/lldb test/stl/a.out
Current executable set to 'test/stl/a.out' (x86_64).
(lldb) breakpoint set --address 0x0000000100000d31
Breakpoint created: 1: address = 0x0000000100000d31, locations = 1

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

about) all the plugin-specific details of getting stack frames
should be hidden behind that, and the "GetStackFrameAtIndex" and "GetStackFrameCount" algorithms become generic. So I moved them to Thread.cpp.

This will allow debugger plug-ins to make any instance of "lldb_private::StopInfo"
that can completely describe any stop reason. It also provides a framework for
doing intelligent things with the stop info at important times in the lifetime
of the inferior.
Examples include the signal stop info in StopInfoUnixSignal. It will check with
the process to see that the current action is for the signal. These actions
include wether to stop for the signal, wether the notify that the signal was
hit, and wether to pass the signal along to the inferior process. The
StopInfoUnixSignal class overrides the "ShouldStop()" method of StopInfo and
this allows the stop info to determine if it should stop at the signal or
continue the process.
StopInfo subclasses must override the following functions:
virtual lldb::StopReason
GetStopReason () const = 0;
virtual const char *
GetDescription () = 0;
StopInfo subclasses can override the following functions:
// If the subclass returns "false", the inferior will resume. The default
// version of this function returns "true" which means the default stop
// info will stop the process. The breakpoint subclass will check if
// the breakpoint wants us to stop by calling any installed callback on
// the breakpoint, and also checking if the breakpoint is for the current
// thread. Signals will check if they should stop based off of the
// UnixSignal settings in the process.
virtual bool
ShouldStop (Event *event_ptr);
// Sublasses can state if they want to notify the debugger when "ShouldStop"
// returns false. This would be handy for breakpoints where you want to
// log information and continue and is also used by the signal stop info
// to notify that a signal was received (after it checks with the process
// signal settings).
virtual bool
ShouldNotify (Event *event_ptr)
{
return false;
}
// Allow subclasses to do something intelligent right before we resume.
// The signal class will figure out if the signal should be propagated
// to the inferior process and pass that along to the debugger plug-ins.
virtual void
WillResume (lldb::StateType resume_state)
{
// By default, don't do anything
}
The support the Mach exceptions was moved into the lldb/source/Plugins/Process/Utility
folder and now doesn't polute the lldb_private::Thread class with platform
specific code.

enabled LLVM make style building and made this compile LLDB on Mac OS X. We
can now iterate on this to make the build work on both linux and macosx.
