Massive test suite cleanup to stop everyone from manually having to compute "mydir" inside each test case. 

This has led to many test suite failures because of copy and paste where new test cases were based off of other test cases and the "mydir" variable wasn't updated.

Now you can call your superclasses "compute_mydir()" function with "__file__" as the sole argument and the relative path will be computed for you.

As consistency, invoke python with /usr/bin/env (like it is done in the rest of the file). Thanks to Xavier De Gaye for the patch

This 'const' is not required and prevent us to defer the launch to the Host layer.

Patch from Xavier de Gaye

llvm-svn: 196830

Previously, an opcode set via SetOpcode32 (for example) was later
extracted via GetData() as a byte sequence in host order rather than
target order.

llvm-svn: 196808

Summary: Now that Host provide a MakeDirectory function, we can use it instead of relying on command line tool to create a directory.

it succeeded, since the plan that was using it can figure out what to do from there.
It should only say it failed if it truely went off into the weeds.

Fixed the GDBRemoteCommuncation to return a new GDBRemoteCommuncation::PacketResult enum for all packet sends/receives.

<rdar://problem/15600045>

Due to other recent changes, all connections to GDB servers that didn't support the "QStartNoAckMode" packet would cause us to fail to attach to the remote GDB server.

The problem was that SendPacket* and WaitForResponse* packets would return a size_t indicating the number of bytes sent/received. The other issue was WaitForResponse* packets would strip the leading '$' and the trailing "#CC" (checksum) bytes, so the unimplemented response packet of "$#00" would get stripped and the WaitForResponse* packets would return 0.

These new error codes give us flexibility to to more intelligent things in response to what is returned.

For logical backtrace work, lldb needs to track Module unloads etc & symoblicate an address based on a point in time

<rdar://problem/15314403> 

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.

Modified local spawning in debugserver processes to use a new --reverse-connect option so that debugserver actually connects back to LLDB instead of LLDB connecting to debugserver.

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.

Revert: "Patch from Todd Fiala that install the lldb.py module in the prefix directory and also makes install fail if the prefix directory can't be accessed"

Does not respect the prefix

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
