23b1decbe7 Add support for specifying a language to use when parsing breakpoints.
Target and breakpoints options were added:
    breakpoint set --language lang --name func
    settings set target.language pascal
These specify the Language to use when interpreting the breakpoint's
expression (note: currently only implemented for breakpoints on
identifiers).  If the breakpoint language is not set, the target.language
setting is used.
This support is required by Pascal, for example, to set breakpoint at 'ns.foo'
for function 'foo' in namespace 'ns'.
Tests on the language were also added to Module::PrepareForFunctionNameLookup
for efficiency.

fbecf1ab1a The session dictionary attached to a Python interpeter holds variables the user creates in the script interpreter
This can include objects that have complex state and need to be torn down intelligently (e.g. our SB* objects)

This will fail if the Python interpreter does not hold a valid thread state. So, acquire one, delete the session dictionary, and then let go of it on destruction

This fixes rdar://20960843

1124045ac7 Don't #include "lldb-python.h" from anywhere.
Since interaction with the python interpreter is moving towards
being more isolated, we won't be able to include this header from
normal files anymore, all includes of it should be localized to
the python library which will live under source/bindings/API/Python
after a future patch.

None of the files that were including this header actually depended
on it anyway, so it was just a dead include in every single instance.

4446487d71 Improve LLDB prompt handling
Summary:
There is an issue in lldb where the command prompt can appear at the wrong time. The partial fix
we have in for this is not working all the time and is introducing unnecessary delays. This
change does:
- Change Process:SyncIOHandler to use integer start id's for synchronization to avoid it being
  confused by quick start-stop cycles. I picked this up from a suggested patch by Greg to
  lldb-dev.
- coordinates printing of asynchronous text with the iohandlers. This is also based on a
  (different) Greg's patch, but I have added stronger synchronization to it to avoid races.

Together, these changes solve the prompt problem for me on linux (both with and without libedit).
I think they should behave similarly on Mac and FreeBSD and I think they will not make matters
worse for windows.

Test Plan: Prompt comes out alright. All tests still pass on linux.

Commands could always check for these things themselves, but having these accessible via flags makes custom commands more consistent with built-in ones

a72b31c79e This is some groundwork for filtering the language Exception
breakpoints, for instance on the class of the thrown object.

This change doesn't actually make that work, the part where we
extract the thrown object type from the throw site isn't done yet.

This provides a general programmatic "precondition" that you can add
to breakpoints to give them the ability to do filtering on the LLDB
side before we pass the stop on to the user-provided conditions & 
callbacks.

dd50f7421c Making linking against Python simpler on Windows.
This patch deprecates the three Python CMake variables in favor of
a single variable PYTHON_HOME which points to the root of a python
installation.  Since building Python doesn't output the files in
a structure that is compatible with the PYTHONHOME environment
variable, we also provide a script install_custom_python.py which
will copy the output of a custom python build to the correct
directory structure.

The supported workflow after this patch will be to build python
once for each configuration and architecture {Debug,Release} x {x86,x64}
and then run the script.  Then run CMake specifying -DPYTHON_HOME=<path>

The first time you do this will probably require you to delete your
CMake cache.

The old workflow is still supported during a transitionary period,
but a warning is printed at CMake time, and this will eventually
be removed.

4e8ddf5333 [Python] Fix issue configuring sys.path during startup.
Previously, users on Windows had to manually specify PYTHONPATH
to point to the site-packages directory before running LLDB.
The reason for this was because sys.path was being initialized
with a path containing unescaped backslashes, causing escape
sequences to end up in the paths.

e7e8e3cd89 Fix check for options in "command alias"
Summary:
"command alias" can add invalid options to the command. "command alias start process launch -s" will add an extra argument, "<no-argument>" to the alias, so it runs "process launch -s <no-argument>", which launches the process with args that include "<no-argument>".

This patch changes the text compare of the variable value with "<OptionParser::eNoArgument>" to a compare of variable value_type with OptionParser::eNoArgument. It also moves the previous test inside the if, so it won't add a trailing space if there is no argument.

48b475cbaa Fix warnings generated by clang-cl.
There were a couple of real bugs here regarding error checking and
signed/unsigned comparisons, but mostly these were just noise.

There was one class of bugs fixed here which is particularly
annoying, dealing with MSVC's non-standard behavior regarding
the underlying type of enums.  See the comment in
lldb-enumerations.h for details.  In short, from now on please use
FLAGS_ENUM and FLAGS_ANONYMOUS_ENUM when defining enums which
contain values larger than can fit into a signed integer.

e6e2bb3842 Rework LLDB system initialization.
In an effort to reduce binary size for components not wishing to
link against all of LLDB, as well as a parallel effort to reduce
link dependencies on Python, this patch splits out the notion of
LLDB initialization into "full" and "common" initialization.

All code related to initializing the full LLDB suite lives directly
in API now.  Previously it was only referenced from API, but because
it was defined in lldbCore, it would get implicitly linked against
by everything including lldb-server, causing a considerable
increase in binary size.

By moving this to the API layer, it also creates a better layering
for the ongoing effort to make the embedded interpreter replacable
with one from a different language (or even be completely removeable).

One semantic change necessary to get this all working was to remove
the notion of a shared debugger refcount.  The debugger is either
initialized or uninitialized now, and calling Initialize() multiple
times will simply have no effect, while the first Terminate() will
now shut it down no matter how many times Initialize() was called.
This behaves nicely with all of our supported usage patterns though,
and allows us to fix a number of nasty hacks from before.

0641ca1a2d Remove ScriptInterpreterObject.
This removes ScriptInterpreterObject from the codebase completely.
Places that used to rely on ScriptInterpreterObject now use
StructuredData::Object and its derived classes.  To support this,
a new type of StructuredData object is introduced, called
StructuredData::Generic, which stores a void*.  Internally within
the python library, StructuredPythonObject subclasses this
StructuredData::Generic class so that it can addref and decref
the python object on construction and destruction.

Additionally, all of the classes in PythonDataObjects.h such
as PythonList, PythonDictionary, etc now provide a method to
create an instance of the corresponding StructuredData type.  For
example, there is PythonDictionary::CreateStructuredDictionary.
To eliminate dependencies on PythonDataObjects for external
callers, all ScriptInterpreter methods now return only
StructuredData classes

The rest of the changes in this CL are focused on fixing up
users of PythonDataObjects classes to use the new StructuredData
classes.

9fe00e52d3 Bulk of the infrastructure work to allow script commands to be backed by object instances in addition to free functions
This works by creating a command backed by a class whose interface should - at least - include

def __init__(self, debugger, session_dict)
def __call__(self, args, return_obj, exe_ctx)

What works:
- adding a command via command script add --class
- calling a thusly created command

What is missing:
- support for custom help
- test cases

The missing parts will follow over the next couple of days

This is an improvement over the existing system as:
a) it provides an obvious location for commands to provide help strings (i.e. methods)
b) it allows commands to store state in an obvious fashion
c) it allows us to easily add features to script commands over time (option parsing and subcommands registration, I am looking at you :-)

00b7f95b12 Fix handling of backslashes in Args parsing
Summary:
Presently Args::SetCommandString allows quotes to be escaped with backslash. However, the
backslash itself is not removed from the argument, nor there is a way to escape the backslash
itself. This leads to surprising results:

"a b" c"   -> 'a b', 'c'  # Here we actually have an unterminated quote, but that is ignored
"a b\" c"  -> 'a b\" c'   # We try to escape the quote. That works but the backslash is not removed.
"a b\\" c" -> 'a b\\" c'  # Escaping the backslash has no effect.

This change changes quote handling to be more shell-like:
- single quotes and backquotes are literal and there is no way to escape the closing quote or
  anything else inside;
- inside double quotes you can use backslash to escape the closing quote and another backslash
- outside any quotes, you can use backslash to escape quotes, spaces and itself.

This makes the parsing more consistent with what the user is familiar and increases the
probability that pasting the command line from shell to the "process launch" command "just work".
