Zachary Turner 97206d5727 Rename Error -> Status.
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.

Pavel Labath 4f1f64174b MainLoop: Add unit tests
Summary:
This adds a couple of unit tests to the MainLoop class. To get the
kqueue based version of the signal handling passing, I needed to
modify the implementation a bit to make the queue object persistent.
Otherwise, only the signals which are send during the Run call would get
processed, which did not match the ppoll behaviour.

I also took the opportunity to remove the ForEach template functions and
replace them with something more reasonable.

Pavel Labath 836ad03fa5 Resurrect pselect MainLoop implementation
Summary:
It turns out that even though ppoll is available on all the android
devices we support, it does not seem to be working properly on all of
them -- MainLoop just does a busy loop with ppoll returning EINTR and
not making any progress.

This brings back the pselect implementation and makes it available on
android. I could not do any cmake checks for this as the ppoll symbol is
actually avaiable -- it just does not work.

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.

This is not ideal, but it should get the bot going again. I'll need to revisit this if we want to get signal handling working on Windows.
