b2e1a5c998 Add a utility function smart_iter() which has knowledge of the getsize and the getelem
method names of all the lldb container objects and returns an iterator object when
passed an eligible lldb container object.

Example:

    from lldb_util import smart_iter
    for thread in smart_iter(process):
        ID = thread.GetThreadID()
        if thread.GetStopReason() == lldb.eStopReasonBreakpoint:
            stopped_due_to_breakpoint = True
        for frame in smart_iter(thread):
            self.assertTrue(frame.GetThread().GetThreadID() == ID)
        ...

Add a test case for lldb.smart_iter().

c5f121e3c0 Add a test case for lldbutil.lldb_iter() which returns an iterator object
for lldb objects which can contain other lldb objects.  Examples are:
SBTarget contains SBModule, SBModule contains SBSymbols, SBProcess contains
SBThread, SBThread contains SBFrame, etc.

79ea878bf9 Got the EmulateInstruction CFI code a lot closer to producing CFI data.
Switch the EmulateInstruction to use the standard RegisterInfo structure
that is defined in the lldb private types intead of passing the reg kind and
reg num everywhere. EmulateInstruction subclasses also need to provide
RegisterInfo structs given a reg kind and reg num. This eliminates the need
for the GetRegisterName() virtual function and allows more complete information
to be passed around in the read/write register callbacks. Subclasses should
always provide RegiterInfo structs with the generic register info filled in as
well as at least one kind of register number in the RegisterInfo.kinds[] array.

2ed751bd47 Changed the emulate instruction function to take emulate options which
are defined as enumerations. Current bits include:

        eEmulateInstructionOptionAutoAdvancePC
        eEmulateInstructionOptionIgnoreConditions

Modified the EmulateInstruction class to have a few more pure virtuals that
can help clients understand how many instructions the emulator can handle:

        virtual bool
        SupportsEmulatingIntructionsOfType (InstructionType inst_type) = 0;


Where instruction types are defined as:

//------------------------------------------------------------------
/// Instruction types
//------------------------------------------------------------------    
typedef enum InstructionType
{
    eInstructionTypeAny,                // Support for any instructions at all (at least one)
    eInstructionTypePrologueEpilogue,   // All prologue and epilogue instructons that push and pop register values and modify sp/fp
    eInstructionTypePCModifying,        // Any instruction that modifies the program counter/instruction pointer
    eInstructionTypeAll                 // All instructions of any kind

}  InstructionType;


This allows use to tell what an emulator can do and also allows us to request
these abilities when we are finding the plug-in interface.

Added the ability for an EmulateInstruction class to get the register names
for any registers that are part of the emulation. This helps with being able
to dump and log effectively.

The UnwindAssembly class now stores the architecture it was created with in
case it is needed later in the unwinding process.

Added a function that can tell us DWARF register names for ARM that goes
along with the source/Utility/ARM_DWARF_Registers.h file: 

        source/Utility/ARM_DWARF_Registers.c
        
Took some of plug-ins out of the lldb_private namespace.

fc87e2dd5c Make SBBreakpointLocation::GetDescription() API to be consistent with SBTarget,
i.e., with 'SBStream &description' first, followed by 'DescriptionLevel level'.

Modify lldbutil.py so that get_description() for a target or breakpoint location
can just take the lldb object itself without specifying an option to mean option
lldb.eDescriptionLevelBrief.  Modify TestTargetAPI.py to exercise this logic path.

7e14f91dbd Fixed the SymbolContext::DumpStopContext() to correctly indent and dump
inline contexts when the deepest most block is not inlined.

Added source path remappings to the lldb_private::Target class that allow it
to remap paths found in debug info so we can find source files that are elsewhere
on the current system.

Fixed disassembly by function name to disassemble inline functions that are
inside other functions much better and to show enough context before the
disassembly output so you can tell where things came from.

Added the ability to get more than one address range from a SymbolContext 
class for the case where a block or function has discontiguous address ranges.

385aa28cf6 Did some work on the "register read" command to only show the first register
set by default when dumping registers. If you want to see all of the register
sets you can use the "--all" option:

(lldb) register read --all

If you want to just see some register sets, you can currently specify them
by index:

(lldb) register read --set 0 --set 2

We need to get shorter register set names soon so we can specify the register
sets by name without having to type too much. I will make this change soon.

You can also have any integer encoded registers resolve the address values
back to any code or data from the object files using the "--lookup" option.
Below is sample output when stopped in the libc function "puts" with some
const strings in registers:

Process 8973 stopped
* thread #1: tid = 0x2c03, 0x00007fff828fa30f libSystem.B.dylib`puts + 1, stop reason = instruction step into

  gs           = 0x0000000000000000

As we can see, we see two constant strings and the PC (register "rip") is 
showing the code it resolves to.

I fixed the register "--format" option to work as expected.

Added a setting to disable skipping the function prologue when setting 
breakpoints as a target settings variable:

(lldb) settings set target.skip-prologue false

Updated the user settings controller boolean value handler funciton to be able
to take the default value so it can correctly respond to the eVarSetOperationClear
operation.

Did some usability work on the OptionValue classes.

Fixed the "image lookup" command to correctly respond to the "--verbose" 
option and display the detailed symbol context information when looking up
line table entries and functions by name. This previously was only working
for address lookups.
