edc4414094 Expose the ability to retrieve the result of a type validator via the SB API. To keep it simple, do not expose the pair, but just return a NULL string for success, and a non-NULL string for error; If we were to decide to expose the pair, we would need an SBTypeValidatorResult, which is fine, but it should come as part of exposing type validators through the SB API rather than as a one-off thing. So, KISS for now

7ab079b6d0 Add an option to suppress the persistent result variable when running EvaluateExpression
from Python.  If you don't need to refer to the result in another expression, there's no
need to bloat the persistent variable table with them since you already have the result
SBValue to work with.

fb903ab7d4 Make the swig generation script use the correct python executable.
It was hardcoding the value "python", which will end up at best
getting a different python executable (if the user has overridden
the value of PYTHON_EXECUTABLE), and at worst encountering an
error (if there is no copy of python on the system path).

This patch changes the script to use sys.executable so that it
runs the sub-script with the same executable that it was run with.

fa59e62012 Create an _d suffixed symlink when doing a debug Windows build.
_lldb is built as an extension module on Windows.  Normally to load
an extension module named 'foo', Python would look for the file
'foo.pyd'.  However, when a debug interpreter is used, Python will
look for the file 'foo_d.pyd'.  This change checks the build
configuration and creates the correct symlink name based on the
build configuration.

0ab4b48992 Get the python scripting interface working on Windows.
This patch fixes a number of issues with embedded Python on
Windows.  In particular:

1) The script that builds the python modules was normalizing the
   case of python filenames during copies.  The module name is
   the filename, and is case-sensitive, so this was breaking code.

2) Changes the build to not attempt to link against python27.lib
   (e.g. the release library) when linking against msvcrt debug
   library.  Doing a debug build of LLDB with embedded python
   support now requires you to provide your own self-compiled
   debug version of python.

3) Don't import termios when initializing the interpreter.  This
   is part of a larger effort to remove the dependency on termios
   since it is not available on Windows.  This particular instance
   was unnecessary and unused.

9b35cf52d2 This creates a valid Python API for Windows, pending some issues. The changes included are -
- Ported the SWIG wrapper shell scripts to Python so that they would work on Windows too along with other platforms
 - Updated CMake handling to fix SWIG errors and manage sym-linking on Windows to liblldb.dll
 - More build fixes for Windows

The pending issues are that two Python modules, termios and pexpect are not available on Windows.
These are currently required for the Python command interpreter to be used from within LLDB.

705b180964 Initial merge of some of the iOS 8 / Mac OS X Yosemite specific
lldb support.  I'll be doing more testing & cleanup but I wanted to
get the initial checkin done.

This adds a new SBExpressionOptions::SetLanguage API for selecting a
language of an expression.

I added adds a new SBThread::GetInfoItemByPathString for retriving
information about a thread from that thread's StructuredData.

I added a new StructuredData class for representing
key-value/array/dictionary information (e.g. JSON formatted data).
Helper functions to read JSON and create a StructuredData object,
and to print a StructuredData object in JSON format are included.

A few Cocoa / Cocoa Touch data formatters were updated by Enrico
to track changes in iOS 8 / Yosemite.

Before we query a thread's extended information, the system runtime may 
provide hints to the remote debug stub that it will use to retrieve values
out of runtime structures.  I added a new SystemRuntime method 
AddThreadExtendedInfoPacketHints which allows the SystemRuntime to add 
key-value type data to the initial request that we send to the remote stub.

The thread-format formatter string can now retrieve values out of a thread's
extended info structured data.  The default thread-format string picks up
two of these - thread.info.activity.name and thread.info.trace_messages.

I added a new "jThreadExtendedInfo" packet in debugserver; I will
add documentation to the lldb-gdb-remote.txt doc soon.  It accepts
JSON formatted arguments (most importantly, "thread":threadnum) and
it returns a variety of information regarding the thread to lldb
in JSON format.  This JSON return is scanned into a StructuredData
object that is associated with the thread; UI layers can query the
thread's StructuredData to see if key-values are present, and if
so, show them to the user.  These key-values are likely to be
specific to different targets with some commonality among many
targets.  For instance, many targets will be able to advertise the
pthread_t value for a thread.

I added an initial rough cut of "thread info" command which will print
the information about a thread from the jThreadExtendedInfo result.
I need to do more work to make this format reasonably.

Han Ming added calls into the pmenergy and pmsample libraries if
debugserver is run on Mac OS X Yosemite to get information about the
inferior's power use.

I added support to debugserver for gathering the Genealogy information
about threads, if it exists, and returning it in the jThreadExtendedInfo
JSON result.

e8daa2f843 Introduce the concept of a "display name" for types
Rationale:
Pretty simply, the idea is that sometimes type names are way too long and contain way too many details for the average developer to care about. For instance, a plain ol' vector of int might be shown as
std::__1::vector<int, std::__1::allocator<....
rather than the much simpler std::vector<int> form, which is what most developers would actually type in their code

Proposed solution:
Introduce a notion of "display name" and a corresponding API GetDisplayTypeName() to return such a crafted for visual representation type name
Obviously, the display name and the fully qualified (or "true") name are not necessarily the same - that's the whole point
LLDB could choose to pick the "display name" as its one true notion of a type name, and if somebody really needs the fully qualified version of it, let them deal with the problem
Or, LLDB could rename what it currently calls the "type name" to be the "display name", and add new APIs for the fully qualified name, making the display name the default choice

The choice that I am making here is that the type name will keep meaning the same, and people who want a type name suited for display will explicitly ask for one
It is the less risky/disruptive choice - and it should eventually make it fairly obvious when someone is asking for the wrong type

Caveats:
- for now, GetDisplayTypeName() == GetTypeName(), there is no logic to produce customized display type names yet.
- while the fully-qualified type name is still the main key to the kingdom of data formatters, if we start showing custom names to people, those should match formatters

9bb71b73d9 Suppress python readline module under Linux to fix a seg fault.
Bug fix for pr18841:
http://llvm.org/bugs/show_bug.cgi?id=18841

This change creates a stub Python readline.so module that does almost
nothing. Its whole purpose is to prevent Python from loading the real
module, something it does during the embedded Python interpreter's
initialization sequence (and way before lldb ever requests it within
embedded_interpreter.py).

On Ubuntu 12.04 and 13.10 x86_64, and in the Python 2.7.6 tree, the
stock Python readline module links against the GNU readline library.
This appears to be the case on all Pythons except where __APPLE__ is
defined. LLDB now requires linking against the libedit library.
Something about having both libedit.so and libreadline.so linked into
the same process space is causing the Python readline.so to trigger a
NULL memory access. I have put in a separate patch to python.org.

This suppression of embedded interpreter readline support can be
removed if at least any one of the following happens:

1. The stock python distribution accepts a patch similar to what I
submitted to Python 2.7.6's Modules/readline.c file.

2. The stock python distribution implements Modules/readline.c in
terms of libedit's readline compatibility mode (i.e. essentially
compiles it the way __APPLE__ compiles that module) under Linux.

3. a clean-room implementation of the python readline module is
implemented against libedit (either readline compatibility mode or
native libedit). This could be implemented within the readline.cpp
file that this change introduces. It cannot be a fork of python's
readline.c module due to llvm licensing.

The net effect of this change on Linux is that the embedded python's
readline support will not exist.

2 - auto completion in python embedded interpreter
3 - multi-line input for "script" and "expression" commands now allow you to edit previous/next lines using up and down arrow keys and this makes multi-line input actually a viable thing to use
4 - it is now possible to use curses to drive LLDB (please try the "gui" command)

30f287fde5 Add a new way to bind a format to a type: by enum type
The "type format add" command gets a new flag --type (-t). If you pass -t <sometype>, upon fetching the value for an object of your type,
LLDB will display it as-if it was of enumeration type <sometype>
This is useful in cases of non-contiguous enums where there are empty gaps of unspecified values, and as such one cannot type their variables as the enum type,
but users would still like to see them as-if they were of the enum type (e.g. DWARF field types with their user-reserved ranges)

        print >> result, '%s installed successfully' % (src)
    else:

The remote lldb-platform can now launch GDB servers on the remote system so that remote debugging can be spawned through the remote platform when connected to a remote platform.

The API in SBPlatform is subject to change and will be getting many new functions.
