lldb -P, which outputs its python path, works by using Host-layer
facilities to get information about the loaded python module. This
Host functionality was unimplemented on Windows, so this patch
implements it. Additionally, it removes a pexpect dependency from
the test runner and uses an equivalent invocation of subprocess.

_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.

- First, when logging, be helpful by printing
the real name of the class;
- Second, up the limit for number of classes
from 16k to 128k, and put in an assertion
(and better error handling when not in a

limit the next time.

The problem was that we have an IOHandler thread that services the IOHandler stack. The command interepter is on the top of the stack and it receives a "expression ..." command, and it calls the IOHandlerIsComplete() callback in the command interpereter delegate which runs an expression. This causes the IOHandlerProcessSTDIO to be pushed, but since we are running the code from the IOHandler thread, it won't get run. When CTRL+C is pressed, we do deliver the interrupt to the IOHandlerProcessSTDIO::Interrupt() function, but it was always writing 'i' to the interrupt pipe, even if we weren't actively reading from the debugger input and the pipes. This fix works around the issue by directly issuing the async interrupt to the process if the process is running.
A longer term more correct fix would to be run the IOHandler thread and have it just do the determination of the input and when complete input is received, run the code that handles that input on another thread and syncronize with that other thread to detect when more input is desired. That change is too big to make right now, so this fix will tide us over until we can get there.

This value gets set to a max uint32_t value when there is no known limit; otherwise,
it is set to a value appropriate for the platform. For the moment, only
Linux, FreeBSD and NetBSD set it to 16. All other platforms set it to
the max uint32_t value.
Modifies the Process private state thread names to fit within a 16-character limit
when the max thread name length is <= 16. These guarantee that the thread names
can be distinguished within the first 16 characters. Prior to this change, those
threads had names in the final dotted name segment that were not distinguishable
within the first 16 characters.

This change comprises of additions and some minor changes in order that
"kalimba" is listed as a supported platform and that debugging any
kalimbas results in PlatformKalimba being associated with the target.
The changes are as follows:
* The PlatformKalimba implementation itself
* A tweak to ArchSpec
* .note parsing for Kalimba in ObjectFileELF.cpp
* Plugin registration
* Makefile additions

Any commands that want interactivity (stdin) will need to be executed through the normal command interpreter using the debugger's in/out/err file handles, or by using "command source".
Individual commands through the API will have their STDIN disabled. The STDOUT and STDERR will be redirected into the SBCommandReturnObject argument to SBCommandInterpreter::HandleCommand() as usual.
This helps with a deadlock situation in an IDE (Xcode) where the IDE was managing the breakpoint actions by setting a breakpoint callback and doing things manually.

Now that llgs supports communicating the 0-port choose-a-port
mechanism and can communicate that back to a caller via the
--named-pipe option (at parity with debugserver), we use this
mechanism to always start llgs and debugserver gdb-remote
protocol tests without needing to use some port arbitration
mechanism. This eliminates some potential intermittent failures vs. the
previous random port and collision-avoidance strategy used.

The fix adds a std::weak_ptr<Module> into the TypeImpl and fills in the weak pointer when possible. It also checks to make sure the module is still alive prior to using it which should make our API safer to use.

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.

Fixes include:
- Don't say that "<arch>-apple-ios" is compatible with "<arch>-apple-macosx"
- Fixed DynamicLoaderMacOSXDYLD so specify an architecture that was converted solely from a cputype and subtype, just specify the file + UUID.
- Fixed PlatformiOSSimulator::GetSupportedArchitectureAtIndex() so it returns the correct archs
- Fixed SymbolFileDWARFDebugMap to load .o files correctly by just specifying the architecture without the vendor and OS now that "<arch>-apple-ios" is not compatible with "<arch>-apple-macosx" so we can load .o files correctly for DWARF with debug map
- Fixed the coded in TargetList::CreateTarget() so it does the right thing with an underspecified triple where just the arch is specified.

These fix the broken debian lldb build, which is using g++ 4.7.2.
TypeFormat changes:
1. stopped using the C++11 "dtor = default;" construct.
The generated default destructor in the two derived classes wanted
them to have a different throws() semantic that was causing 4.7 to
fail to generate it. I switched these to empty destructors defined
in the .cpp file.
2. Switched the m_types map from an ordered map to an unordered_map.
g++ 4.7's c++ library supports the C++11 emplace() used by TypeFormat
but the same c++ library's map impl does not. Since TypeFormat didn't
look like it depended on ordering in the map, I just switched it to
a std::unordered_map.
NativeProcessLinux - g++ 4.7 chokes on lexing the "<::" in
static_cast<::pid_t>(wpid). g++ 4.8+ and clang are fine with it.
I just put a space in between the "<" and the "::" and that cleared
it up.

The current strategy for host allocation is to choose a random
address and attempt to allocate there, eventually failing if the
allocation cannot be satisfied.
The C standard only guarantees that RAND_MAX >= 32767, so for
platforms that use a very small RAND_MAX allocations will fail
with very high probability. On such platforms (Windows is one),
you can reproduce this trivially by running lldb, typing "expr (3)"
and then hitting enter you see a failure. Failures generally
happen with a frequency of about 1 failure every 5 evaluations.
There is no good reason that allocations need to look like "real"
pointers, so this patch changes the allocation scheme to simply
jump straight to the end and grab a free chunk of memory.

The getopt library has a structure called option (lowercase). We
have a structure called Option (uppercase). previously the two
structures had exactly the same definitions, and we were doing a
C-style cast of an Option* to an option*. C-style casts don't
bother to warn you when you cast to unrelated types, but in the
original OptionValidator patch I modified the definition of Option.
This patch fixes the errors by building an array of option
structures and filling it out the correct way before passing it to
the getopt library.
This also fixes one other source of test failures: an uninitialized
read that occurs due to not initializing a field of the
OptionDefinition.

This patch implements basic functionality of the "platform process
list" command for Windows. Currently this has the following
limitations.
* Certain types of filtering are not enabled (e.g. filtering by
architecture with -a), although most filters work.
* The username of the process is not yet obtained.
* Using -v to list verbose information generates an error.
* The architecture column displays the entire triple, leading to
misaligned formatting of the printed table.
