Chris Bieneman 1182779917 Re-landing IPv6 support for LLDB Host
This support was landed in r300579, and reverted in r300669 due to failures on the bots.

The failures were caused by sockets not being properly closed, and this updated version of the patches should resolve that.

Summary from the original change:

This patch adds IPv6 support to LLDB/Host's TCP socket implementation. Supporting IPv6 involved a few significant changes to the implementation of the socket layers, and I have performed some significant code cleanup along the way.

This patch changes the Socket constructors for all types of sockets to not create sockets until first use. This is required for IPv6 support because the socket type will vary based on the address you are connecting to. This also has the benefit of removing code that could have errors from the Socket subclass constructors (which seems like a win to me).

The patch also slightly changes the API and behaviors of the Listen/Accept pattern. Previously both Listen and Accept calls took an address specified as a string. Now only listen does. This change was made because the Listen call can result in opening more than one socket. In order to support listening for both IPv4 and IPv6 connections we need to open one AF_INET socket and one AF_INET6 socket. During the listen call we construct a map of file descriptors to addrin structures which represent the allowable incoming connection address. This map removes the need for taking an address into the Accept call.

This does have a change in functionality. Previously you could Listen for connections based on one address, and Accept connections from a different address. This is no longer supported. I could not find anywhere in LLDB where we actually used the APIs in that way. The new API does still support AnyAddr for allowing incoming connections from any address.

The Listen implementation is implemented using kqueue on FreeBSD and Darwin, WSAPoll on Windows and poll(2) everywhere else.

Pavel Labath 107e694271 Revert yesterdays IPv6 patches
The break the linux bots (and probably any other machine which would
run the test suite in a massively parallel way). The problem is that it
can happen that we only successfully create an IPv6 listening socket
(because the relevant IPv4 port is used by another process) and then the
connecting side attempts to connect to the IPv4 port and fails.

It's not very obvious how to fix this problem, so I am reverting this
until we come up with a solution.

Chris Bieneman d01a2fa38d Update DebugServer to support IPv6 over TCP
Summary: This patch adds IPv6 support to debugserver. It follows a similar pattern to the changes proposed for LLDB/Host except that the listen implementation is only with kqueue(2) because debugserver is only supported on Darwin.

Chris Bieneman efd065e6a0 Support Unit Testing debugserver
Summary:
This patch refactors the CMake build system's support for building debugserver to allow us to build the majority of debugserver's sources into the debugserverCommon library which can then be reused by unit tests.

The first unit test I've written tests debug server's ability to accept incoming connections from LLDB. The test forks the process, and one side creates a listening socket using debugserver's socket API, the other side creates a transmitting socket using LLDB's TCPSocket class.

I have no clue where to even start getting this connected into the LLDB Xcode project, so for now these tests are CMake-only.

Chris Bieneman 494f277af5 [CMake] Add accurate dependency specifications
Summary:
This patch adds accurate dependency specifications to the mail LLDB libraries and tools.

In all cases except lldb-server, these dependencies are added in addition to existing dependencies (making this low risk), and I performed some code cleanup along the way.

For lldb-server I've cleaned up the LLVM dependencies down to just the minimum actually required. This is more than lldb-server actually directly references, and I've left a todo in the code to clean that up.

The class is only used in the debugserver. The rest of lldb has the StringExtractor class.

Xcode project will need to be updated after this.

Todd Fiala eeb023cf76 Fix codesigning of MacOSX debugserver when built with cmake.
This patch fixes the codesigning of debugserver on OSX when built with
cmake.  Without this you get this error when debugging:
    error: process launch failed: unable to locate debugserver

Note: you also need to set LLDB_DEBUGSERVER_PATH to point to your built debugserver.
e.g. export LLDB_DEBUGSERVER_PATH=`pwd`/bin/debugserver

Change by dawn@burble.org.

Tested on MacOSX 10.9.5 and Xcode 6.1 Beta using cmake/ninja.
Verified no build break on Linux Ubuntu cmake/ninja and Xcode 6.1 canonical build.
