Do not hardcode the uuid length
Implement -[CDLCUUID extraDescription] for easier debugging

Use NSUUID instead of CFUUIDRef
Choose custom root SDK path depending on an Xcode location

Set custom root SDK path (using `--sdk-ios` & `--sdk-mac` command line args) to be based on current Xcode location.

The behaviour is from `xcode-select` utility: if there is an `/Applications/Xcode.app`, we choose it. If not — we check for `/Developer`.
Update usage info according to a new `--sdk-ios`/`--sdk-mac` behaviour
Avoid costly autorelease pool drain
Optimization: access ivars directly in CDDataCursor
Optimization: access ivars directly in CDMachOFileDataCursor
Optimization: delete -[CDType init] method that does nothing useful
Return cached class when available
Optimization: access ivars directly in CDType
Optimization: access ivars directly in CDTypeLexer
Correctly resolve imports for external classes:
-Replaced CDOCClass’s superClassName with a superClass object that can be either a reference to an internal class (CDOCClass instance) or a symbol representing an external class (CDSymbol instance)
-Map external class symbols in CDLCSymbolTable
-Fixed some bugs with mapping library ordinals to symbols
-Append “-Protocol” to protocol imports to match the behaviour of class-dump’s exporting of protocol headers
-Map CoreFoundation NS* classes to Foundation imports, so imports for NSObject, NSArray, etc use the public headers by default
Use current framework for protocol imports (since they’re currently all declared in the dump for that framework, rather than attempting to infer their real source framework)
-Correctly handle object types with both a class name and a protocol (ie. NSObject<NSCopying> *) referenced in methods and ivars
-Add imports for protocols referenced in types
Forward-declare protocols instead of importing them when possible
-Fixed a check for id types in protocol type string
-Nitpicking protocol type styling (removed the space between the type and the protocol)
-Replaced CDOCCategory’s className property with classRef, which can handle a CDOCClass, CDSymbol, or NSString, and infer the class name based on that
-When a category class is external (ie. the classRef property is a CDSymbol), use the symbol’s source dylib path to import the source framework correctly
-Reverted ObjC1 processor to use its existing behaviour for handling superclasses (just use the raw string), and added the ability for CDOCClass to handle an NSString for superClass to return the correct superClassName
