This patch adds a new lldb_private::SectionLoadHistory class that tracks what shared libraries were loaded given a process stop ID. This allows us to keep a history of the sections that were loaded for a time T. Many items in history objects will rely upon the process stop ID in the future.

This gets rid of our hacky "get_random_port()" which would grab a random port and tell debugserver to open that port. Now LLDB creates, binds, listens and accepts a connection by binding to port zero and sending the correctly bound port down as the host:port to connect back to.
Fixed the "ConnectionFileDescriptor" to be able to correctly listen for connections from a specified host, localhost, or any host. Prior to this fix "listen://" only accepted the following format:
listen://<port>
But now it can accept:
listen://<port> // Listen for connection from localhost on port <port>
listen://<host>:<port> // Listen for connection from <host> and <port>
listen://*:<port> // Listen for connection from any host on port <port>

@skipIfRemote is used to decorate test cases that don't make sense to run remotely.
@skipIfRemoteDueToDeadlock indicates these tests need to be looked at and currently deadlock the running of the test suite when run on remote systems. These issues should be fixed soon.

This is not being used yet, and in practice, more refactoring would be required to make this fully practical
In practice, the way this should work is that CalculateNumChildren(), GetChildAtIndex(), GetIndexOfChildWithName() and MightHaveChildren() should all default to failure values when m_valid == false. Update() should be the only function actually setting/clearing the flag upon inspecting the backend ValueObject, if it determines it to be in an incongruent state
Given refactoring of the FrontEnd APIs, this work could be automatically performed without the individual providers having to replicate this logic
The way this works now is that each front end picks one or more “key ivars” and keys off those to detect invalidity
This is a baby step 0 to a better world

This helps ensure that the launched debugserver is ready and listening for a connection. Prior to this we had a race condition.
Consolidate the launching of debugserver into a single place: a static function in GDBRemoteCommunication.

This will get the temporary directory on the current system.
Removed a call to tmpnam() and replaced it with a call to mktemp() using a template that will be in the temp directory.

Fix use of std::lower_bound to check for equality if a match is found to ensure we don't return the next breakpoint with an ID greater than the break_id that was asked for.

the build being broken for people using the public Mac OS X 10.9 SDK,
which does not have the Python framework any longer. The Xcode project
file already sets the -I and -L flags correctly so that <Python.h> and
-lpython will work correctly with the system's installed Python.

complete lack of rows, or a row that fails to define a register to
base the CFA off of.

This should probably be replaced with build infrastructure support for
a platform-specific canonical Python include path, but for now it should
restore the FreeBSD buildbot.

lldb_private::Debugger was #including some "lldb/API" header files which causes tools (lldb-platform and lldb-gdbserver) that link against the internals only (no API layer) to fail to link depending on which calls were being used.
Also fixed the current working directory so that it gets set correctly for remote test suite runs. Now the remote working directory is set to: "ARCH/TESTNUM/..." where ARCH is the current architecture name and "TESTNUM" is the current test number.
Fixed the "lldb-platform" and "lldb-gdbserver" to not warn about mismatched visibility settings by having each have their own exports file which contains nothing. This forces all symbols to not be exported, and also quiets the linker warnings.

Summary:
- Stop to try to rebuild llvm on each invocation by removing the invalid library entry libLLVMArchive.a which no longer exists.
- Remove the useless ranlib invocation. "libtools -static" automatically takes care of the archive table of content.

Separate ELF note implementations were introduced for core files and
GNU build-id. Move the more general one from elf-core to ObjectFileELF
and use it for build-id as well.

A number of tests fail to build on FreeBSD because the test build script
defaults to libstdc++ for clang. On FreeBSD the libstdc++ is rather old
and libc++ should be used instead.
(These tests previously had an @expectedFailureFreeBSD decorator for
pr16696, the umbrella PR for the lack of threaded inferior support on
FreeBSD. The work to add that support will be committed soon.)

Added _WIN32 guards to new platform features. Using correct SetErrorStringWithFormat within Host when LLDB_DISABLE_POSIX is defined. Also fixed an if defined block.

From Jim Ingham's email:
It does look like ThreadPlanStepInRange test is some kind of thinko.
In practice, in this case it is probably safe to run only one thread
when doing the "step through" since that generally involved running
from a shared library stub to its target. That could deadlock if the
dynamic loader has to fix up the symbol, and another thread is in the
middle of doing that. But that doesn't seem to be very common, or at
least the code is clearly wrong but I haven't had any reports of this
causing deadlocks...

Although ptrace() can be passed a PID or TID for PT_CONTINUE and PT_STEP,
the kernel operates on all threads in the process in both cases. (See
the FOREACH_THREAD_IN_PROC in FreeBSD's sys_process.c:kern_ptrace.)
Make this clear by using the PID from the ProcessMonitor instance.

the installed SDK to using the current OS installed headers/libraries.
This change is to address the removal of the Python framework
from the Mac OS X 10.9 (Mavericks) SDK, and is the recommended
workaround via https://developer.apple.com/library/mac/technotes/tn2328/_index.html

SmallPtrSet.cpp use different methods if SmallPtrSet.h is included
in C++11 mode. Building llvm in C++03 mode and lldb in C++11 mode
resulted in a link-time failure with the C++11-mode-specific method
not being found in the llvm build.

Improved the detection of a valid GDB server where we actually can connect to a socket, but then it doesn't read or write anything (which happens with some USB mux software).
Host::MakeDirectory() now can make as many intermediate directories as needed.
The testsuite now has very initial support for remote test suite running. When running on a remote platform, the setUp function for the test will make a new directory and select it as the working directory on the remote host.
Added a common function that can be used to create the short option string for getopt_long calls.
