Renamed the "dispatchqaddr" setting that was coming back for stop reply packets
to be named "qaddr" so that gdb doesn't thing it is a register number. gdb
was checking the first character and assuming "di" was a hex register number
because 'd' is a hex digit. It has been shortened so gdb can safely ignore it.

Some functions (particularly varargs functions)
are BitCast before being called, and the problem
was that a CallInst where getCalledValue()
returned a BitCast ConstantExpr was not being
relocated at all.

This problem should now be resolved for the case
of BitCast.

new change will omit unneeded symbol table entries and coalesce
function entries (N_FUN stab entries) with their linker code
symbol (N_SECT symbols) into only the function symbol to avoid
duplicate symbol table entries. It will also coalesce N_STSYM and

member variables.

Modified lldb_private::Module to have an accessor that can be used to tell if
a module is a dynamic link editor (dyld) as there are functions in dyld on
darwin that mirror functions in libc (malloc, free, etc) that should not
be used when doing function lookups by name in expressions if there are more
than one match when looking up functions by name.

expressions correctly.  These produced a result
variable with an initializer but no store
instruction, and the store instruction was as
a result never rewritten to become a store to a
persistent variable.

Now if the result variable has an initializer
but is never used, we generate a (redundant)
store instruction for it, which is then later
rewritten into a (useful) store to the persistent
result variable.

parent, sibling and first child block, and access to the
inline function information.

Added an accessor the StackFrame:

	Block * lldb_private::StackFrame::GetFrameBlock();
	
LLDB represents inline functions as lexical blocks that have
inlined function information in them. The function above allows
us to easily get the top most lexical block that defines a stack
frame. When there are no inline functions in function, the block
returned ends up being the top most block for the function. When
the PC is in an inlined funciton for a frame, this will return the
first parent block that has inlined function information. The
other accessor: StackFrame::GetBlock() will return the deepest block
that matches the frame's PC value. Since most debuggers want to display
all variables in the current frame, the Block returned by
StackFrame::GetFrameBlock can be used to retrieve all variables for
the current frame.

Fixed the lldb_private::Block::DumpStopContext(...) to properly
display inline frames a block should display all of its inlined
functions. Prior to this fix, one of the call sites was being skipped.
This is a separate code path from the current default where inlined
functions get their own frames.

Fixed an issue where a block would always grab variables for any
child inline function blocks.

Fixed an error that could occur during disassembly that could cause a function name to be printed before the first _and_ the second instruction of disassembly when there are two symbols -- one debug symbol and one linker symbol.

This is a very large commit that completely re-does the way lldb
handles user settable internal variables (the equivalent of set/show
variables in gdb).  In addition to the basic infrastructure (most of
which is defined in UserSettingsController.{h,cpp}, there are examples
of two classes that have been set up to contain user settable
variables (the Debugger and Process classes).  The 'settings' command
has been modified to be a command-subcommand structure, and the 'set',
'show' and 'append' commands have been moved into this sub-commabnd
structure.  The old StateVariable class has been completely replaced
by this, and the state variable dictionary has been removed from the
Command Interpreter.  Places that formerly accessed the state variable
mechanism have been modified to access the variables in this new
structure instead (checking the term-width; getting/checking the
prompt; etc.)

Variables are attached to classes; there are two basic "flavors" of
variables that can be set: "global" variables (static/class-wide), and
"instance" variables (one per instance of the class).  The whole thing
has been set up so that any global or instance variable can be set at
any time (e.g. on start up, in your .lldbinit file), whether or not
any instances actually exist (there's a whole pending and default
values mechanism to help deal with that).
