5dfd49ccba New formatting symbol %# can be used in summary strings to get the "count of children" of a variable
- accordingly, the test cases for the synthetic providers for the std:: containers have been edited to use
   ${svar%#} instead of ${svar.len} to print out the count of elements ; the .len synthetic child has been
   removed from the synthetic providers
The synthetic children providers for the std:: containers now return None when asked for children indexes >= num_children()
Basic code to support filter names based on regular expressions (WIP)

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

c53114e30a new flag -P to type synth add lets you type a Python class interactively
added a final newline to fooSynthProvider.py
new option to automatically save user input in InputReaderEZ
checking for NULL pointers in several new places

a37a065c33 Python synthetic children:
- you can now define a Python class as a synthetic children producer for a type
   the class must adhere to this "interface":
        def __init__(self, valobj, dict):
     	def get_child_at_index(self, index):
     	def get_child_index(self, name):
   then using type synth add -l className typeName
   (e.g. type synth add -l fooSynthProvider foo)
   (This is still WIP with lots to be added)
   A small test case is available also as reference

d55546b27a when typing a summary string you can use the %S symbol to explicitly indicate that you want the summary to be used to print the target object
(e.g. ${var%S}). this might already be the default if your variable is of an aggregate type
new feature: synthetic filters. you can restrict the number of children for your variables to only a meaningful subset
 - the restricted list of children obeys the typical rules (e.g. summaries prevail over children)
 - one-line summaries show only the filtered (synthetic) children, if you type an expanded summary string, or you use Python scripts, all the real children are accessible
 - to provide a synthetic children list use the "type synth add" command, as in:
   type synth add foo_type --child varA --child varB[0] --child varC->packet->flags[1-4]
   (you can use ., ->, single-item array operator [N] and bitfield operator [N-M]; array slice access is not supported, giving simplified names to expression paths is not supported)
 - a new -S option to frame variable and target variable lets you override synthetic children and instead show real ones

20edcdbe8a The implementation of categories is now synchronization safe
Code cleanup:
 - The Format Manager implementation is now split between two files: FormatClasses.{h|cpp} where the
   actual formatter classes (ValueFormat, SummaryFormat, ...) are implemented and
   FormatManager.{h|cpp} where the infrastructure classes (FormatNavigator, FormatManager, ...)
   are contained. The wrapper code always remains in Debugger.{h|cpp}
 - Several leftover fields, methods and comments from previous design choices have been removed
type category subcommands (enable, disable, delete) now can take a list of category names as input
 - for type category enable, saying "enable A B C" is the same as saying
    enable C
    enable B
    enable A
   (the ordering is relevant in enabling categories, and it is expected that a user typing
    enable A B C wants to look into category A, then into B, then into C and not the other
    way round)
 - for the other two commands, the order is not really relevant (however, the same inverted ordering
   is used for consistency)
