81e871ed76 Convert all python objects in our API to use overload the __str__ method
instead of the __repr__. __repr__ is a function that should return an
expression that can be used to recreate an python object and we were using
it to just return a human readable string.

Fixed a crasher when using the new implementation of SBValue::Cast(SBType).

Thread hardened lldb::SBValue and lldb::SBWatchpoint and did other general
improvements to the API.

Fixed a crasher in lldb::SBValue::GetChildMemberWithName() where we didn't
correctly handle not having a target.

c14ee32db5 Converted the lldb_private::Process over to use the intrusive
shared pointers.

Changed the ExecutionContext over to use shared pointers for
the target, process, thread and frame since these objects can
easily go away at any time and any object that was holding onto
an ExecutionContext was running the risk of using a bad object.

Now that the shared pointers for target, process, thread and
frame are just a single pointer (they all use the instrusive
shared pointers) the execution context is much safer and still
the same size. 

Made the shared pointers in the the ExecutionContext class protected
and made accessors for all of the various ways to get at the pointers,
references, and shared pointers.

9910bc855d Fixed an issue where the KVO swizzled type would be returned as the dynamic type instead of the actual user-level type
- see the test case in lang/objc/objc-dynamic-value for an example
Objective-C dynamic type lookup now works for every Objective-C type
 - previously, true dynamic lookup was only performed for type id

d8b5fce230 bug fix in SBValue::CreateValueFromAddress() where using the resulting VO as a pointer would crash LLDB ; minor improvements in dynamic formatters lookup

c3e320a7a0 Fixed a bug where a variable could not be formatted in a summary if its datatype already had a custom format
Fixed a bug where Objective-C variables coming out of the expression parser could crash the Python synthetic providers:
 - expression parser output has a "frozen data" component, which is a byte-exact copy of the value (in host memory),
   if trying to read into memory based on the host address, LLDB would crash. we are now passing the correct (target)
   pointer to the Python code
Objective-C "id" variables are now formatted according to their dynamic type, if the -d option to frame variable is used:
 - Code based on the Objective-C 2.0 runtime is used to obtain this information without running code on the target

6f3533fb1d Public API changes:
- Completely new implementation of SBType
 - Various enhancements in several other classes
Python synthetic children providers for std::vector<T>, std::list<T> and std::map<K,V>:
 - these return the actual elements into the container as the children of the container
 - basic template name parsing that works (hopefully) on both Clang and GCC
 - find them in examples/synthetic and in the test suite in functionalities/data-formatter/data-formatter-python-synth
New summary string token ${svar :
 - the syntax is just the same as in ${var but this new token lets you read the values
   coming from the synthetic children provider instead of the actual children
 - Python providers above provide a synthetic child len that returns the number of elements
   into the container
Full bug fix for the issue in which getting byte size for a non-complete type would crash LLDB
Several other fixes, including:
 - inverted the order of arguments in the ClangASTType constructor
 - EvaluationPoint now only returns SharedPointer's to Target and Process
 - the help text for several type subcommands now correctly indicates argument-less options as such

644247c1dc Added "target variable" command that allows introspection of global
variables prior to running your binary. Zero filled sections now get
section data correctly filled with zeroes when Target::ReadMemory
reads from the object file section data.

Added new option groups and option values for file lists. I still need
to hook up all of the options to "target variable" to allow more complete
introspection by file and shlib.

Added the ability for ValueObjectVariable objects to be created with
only the target as the execution context. This allows them to be read
from the object files through Target::ReadMemory(...). 

Added a "virtual Module * GetModule()" function to the ValueObject
class. By default it will look to the parent variable object and
return its module. The module is needed when we have global variables
that have file addresses (virtual addresses that are specific to
module object files) and in turn allows global variables to be displayed
prior to running.

Removed all of the unused proxy object support that bit rotted in 
lldb_private::Value.

Replaced a lot of places that used "FileSpec::Compare (lhs, rhs) == 0" code
with the more efficient "FileSpec::Equal (lhs, rhs)".

Improved logging in GDB remote plug-in.

0a3958e046 several improvements to "type summary":
- type names can now be regular expressions (exact matching is done first, and is faster)
 - integral (and floating) types can be printed as bitfields, i.e. ${var[low-high]} will extract bits low thru high of the value and print them
 - array subscripts are supported, both for arrays and for pointers. the syntax is ${*var[low-high]}, or ${*var[]} to print the whole array (the latter only works for statically sized arrays)
 - summary is now printed by default when a summary string references a variable. if that variable's type has no summary, value is printed instead. to force value, you can use %V as a format specifier
 - basic support for ObjectiveC:
  - ObjectiveC inheritance chains are now walked through
  - %@ can be specified as a summary format, to print the ObjectiveC runtime description for an object
 - some bug fixes

e305594277 Centralize all of the type name code so that we always strip the leading
"struct ", "class ", and "union " from the start of any type names that are
extracted from clang QualType objects. I had to fix test suite cases that
were expecting the struct/union/class prefix to be there.

2837b766f5 Change "frame var" over to using OptionGroups (and thus the OptionGroupVariableObjectDisplay).
Change the boolean "use_dynamic" over to a tri-state, no-dynamic, dynamic-w/o running target,
and dynamic with running target.

58b59f9522 Fix up how the ValueObjects manage their life cycle so that you can hand out a shared
pointer to a ValueObject or any of its dependent ValueObjects, and the whole cluster will
stay around as long as that shared pointer stays around.

78a685aa2d Add support for "dynamic values" for C++ classes. This currently only works for "frame var" and for the
expressions that are simple enough to get passed to the "frame var" underpinnings.  The parser code will
have to be changed to also query for the dynamic types & offsets as it is looking up variables.

The behavior of "frame var" is controlled in two ways.  You can pass "-d {true/false} to the frame var
command to get the dynamic or static value of the variables you are printing.

There's also a general setting:

target.prefer-dynamic-value (boolean) = 'true'

which is consulted if you call "frame var" without supplying a value for the -d option.
