A lot of comments in LLDB are surrounded by an ASCII line to delimit the
begging and end of the comment.
Its use is not really consistent across the code base, sometimes the
lines are longer, sometimes they are shorter and sometimes they are
omitted. Furthermore, it looks kind of weird with the 80 column limit,
where the comment actually extends past the line, but not by much.
Furthermore, when /// is used for Doxygen comments, it looks
particularly odd. And when // is used, it incorrectly gives the
impression that it's actually a Doxygen comment.
I assume these lines were added to improve distinguishing between
comments and code. However, given that todays editors and IDEs do a
great job at highlighting comments, I think it's worth to drop this for
the sake of consistency. The alternative is fixing all the
inconsistencies, which would create a lot more churn.

to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Turns out WITH_LOCKDOWN define changes the struct layout and constructor implementation for RNBSocket which is used in debugserver.cpp, so we need to make sure this is consistent.
In the future we should change WITH_LOCKDOWN to be configured in a generated header, but for now we can just set it correctly.

While adding IPv6 support to debugserver I broke handling wildcard addresses and fully qualified address filtering. This patch resolves that bug and adds a test for matching the address "*".

This renames the LLDB error class to Status, as discussed
on the lldb-dev mailing list.
A change of this magnitude cannot easily be done without
find and replace, but that has potential to catch unwanted
occurrences of common strings such as "Error". Every effort
was made to find all the obvious things such as the word "Error"
appearing in a string, etc, but it's possible there are still
some lingering occurences left around. Hopefully nothing too
serious.

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.

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.

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.

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.
