Log:
Add a new tool named "lldb-vscode" that implements the Visual Studio Code Debug Adaptor Protocol

This patch adds a new lldb-vscode tool that speaks the Microsoft Visual Studio Code debug adaptor protocol. It has full unit tests that test all packets.

This tool can be easily packaged up into a native extension and used with Visual Studio Code, and it can also be used by Nuclide

+# Introduction
+
+The `lldb-vscode` tool creates a command line tool that implements the [Visual
+Studio Code Debug API](https://code.visualstudio.com/docs/extensionAPI/api-debugging).
+It can be installed as an extension for the Visual Studio Code and Nuclide IDE. 
+The protocol is easy to run remotely and also can allow other tools and IDEs to
+get a full featured debugger with a well defined protocol. 
+
+# Intallation for Visual Studio Code
+
+Installing the plug-in involves creating a directory in the `~/.vscode/extensions` folder and copying the package.json file that is in the same directory as this
+documentation into it, and copying to symlinking a lldb-vscode binary into 
+the `bin` directory inside the plug-in directory.
+
+If you want to make a stand alone plug-in that you can send to others on unix systems:
+
+```
+$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
+$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
+$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
+$ cp /path/to/a/built/lldb-vscode .
+$ cp /path/to/a/built/liblldb.so .
+```
+
+
+If you want to make a stand alone plug-in that you can send to others on macOS systems:
+
+```
+$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
+$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
+$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
+$ cp /path/to/a/built/lldb-vscode .
+$ rsync -av /path/to/a/built/LLDB.framework LLDB.framework
+```
+
+You might need to create additional directories for the `liblldb.so` or `LLDB.framework` inside or next to the `bin` folder depending on how the [rpath](https://en.wikipedia.org/wiki/Rpath) is set in your `lldb-vscode` binary. By default the `Debug` builds of LLDB usually includes
+the current executable directory in the rpath, so these steps should work for most people.
+
+To create a plug-in that symlinks into your `lldb-vscode` in your build directory:
+
+```
+$ mkdir -p ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
+$ cp package.json ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0
+$ cd ~/.vscode/extensions/llvm-org.lldb-vscode-0.1.0/bin
+$ ln -s /path/to/a/built/lldb-vscode
+```
+
+This is handy if you want to debug and develope the `lldb-vscode` executable when adding features or fixing bugs.
+
+# Configurations
+
+Launching to attaching require you to create a [launch configuration](https://code.visualstudio.com/Docs/editor/debugging#_launch-configurations). This file
+defines arguments that get passed to `lldb-vscode` and the configuration settings
+control how the launch or attach happens.
+
+## Launch Configuration Settings
+
+When you launch a program with Visual Studio Code you will need to create a [launch.json](https://code.visualstudio.com/Docs/editor/debugging#_launch-configurations)
+file that defines how your program will be run. The JSON configuration file can contain the following `lldb-vscode` specific launch key/value pairs:
+
+|parameter          |type|req |         |
+|-------------------|----|:--:|---------|
+|**name**           |string|Y| A configuration name that will be displayed in the IDE.
+|**type**           |string|Y| Must be "lldb-vscode".
+|**request**        |string|Y| Must be "launch".
+|**program**        |string|Y| Path to the executable to launch.
+|**args**           |[string]|| An array of command line argument strings to be passed to the program being launched.
+|**cwd**            |string| | The program working directory.
+|**env**            |dictionary| | Environment variables to set when launching the program. The format of each environment variable string is "VAR=VALUE" for environment variables with values or just "VAR" for environment variables with no values.
+|**stopOnEntry**    |boolean| | Whether to stop program immediately after launching.
+|**initCommands**   |[string]| | LLDB commands executed upon debugger startup prior to creating a the LLDB target. Commands and command output will be sent to the debugger console when they are executed.
+|**preRunCommands** |[string]| | LLDB commands executed just before launching after the LLDB target has been created. Commands and command output will be sent to the debugger console when they are executed.
+|**stopCommands**   |[string]| | LLDB commands executed just after each stop. Commands and command output will be sent to the debugger console when they are executed.
+|**exitCommands**   |[string]| | LLDB commands executed when the program exits. Commands and command output will be sent to the debugger console when they are executed.
+|**sourceMap**      |[string[2]]| | Specify an array of path re-mappings. Each element in the array must be a two element array containing a source and destination pathname.
+|**debuggerRoot**   | string| |Specify a working directory to use when launching lldb-vscode. If the debug information in your executable contains relative paths, this option can be used so that `lldb-vscode` can find source files and object files that have relative paths.
+
+## Attaching Settings
+
+When attaching to a process using LLDB you can attach in a few ways
+
+1. Attach to an existing process using the process ID
+2. Attach to an existing process by name
+3. Attach by name by waiting for the next instance of a process to launch
+
+The JSON configuration file can contain the following `lldb-vscode` specific launch key/value pairs:
+
+|parameter          |type    |req |         |
+|-------------------|--------|:--:|---------|
+|**name**           |string  |Y| A configuration name that will be displayed in the IDE.
+|**type**           |string  |Y| Must be "lldb-vscode".
+|**request**        |string  |Y| Must be "attach".
+|**program**        |string  | | Path to the executable to attach to. This value is optional but can help to resolve breakpoints prior the attaching to the program.
+|**pid**            |number  | | The process id of the process you wish to attach to. If **pid** is omitted, the debugger will attempt to attach to the program by finding a process whose file name matches the file name from **porgram**. Setting this value to `${command:pickMyProcess}` will allow interactive process selection in the IDE.
+|**stopOnEntry**    |boolean| | Whether to stop program immediately after launching.
+|**waitFor**        |boolean | | Wait for the process to launch.
+|**initCommands**   |[string]| | LLDB commands executed upon debugger startup prior to creating a the LLDB target. Commands and command output will be sent to the debugger console when they are executed.
+|**preRunCommands** |[string]| | LLDB commands executed just before launching after the LLDB target has been created. Commands and command output will be sent to the debugger console when they are executed.
+|**stopCommands**   |[string]| | LLDB commands executed just after each stop. Commands and command output will be sent to the debugger console when they are executed.
+|**exitCommands**   |[string]| | LLDB commands executed when the program exits. Commands and command output will be sent to the debugger console when they are executed.
+|**attachCommands** |[string]| | LLDB commands that will be executed after **preRunCommands** which take place of the code that normally does the attach. The commands can create a new target and attach or launch it however desired. This allows custom launch and attach configurations. Core files can use `target create --core /path/to/core` to attach to core files.
+
+
+## Example configurations
+
+### Launching
+
+This will launch `/tmp/a.out` with arguments `one`, `two`, and `three` and
+adds `FOO=1` and `bar` to the environment:
+
+```javascript
+{
+  "type": "lldb-vscode",
+  "request": "launch",
+  "name": "Debug",
+  "program": "/tmp/a.out",
+  "args": [ "one", "two", "three" ],
+  "env": [ "FOO=1", "BAR" ],
+}
+```
+
+### Attach using PID
+
+This will attach to a process `a.out` whose process ID is 123:
+
+```javascript
+{
+  "type": "lldb-vscode",
+  "request": "attach",
+  "name": "Attach to PID",
+  "program": "/tmp/a.out",
+  "pid": 123
+}
+```
+
+### Attach by Name
+
+This will attach to an existing process whose base
+name matches `a.out`. All we have to do is leave the `pid` value out of the
+above configuration:
+
+```javascript
+{
+  "name": "Attach to Name",
+  "type": "lldb-vscode",
+  "request": "attach",
+  "program": "/tmp/a.out",
+}
+```
+
+If you want to ignore any existing a.out processes and wait for the next instance
+to be launched you can add the "waitFor" key value pair:
+
+```javascript
+{
+  "name": "Attach to Name (wait)",
+  "type": "lldb-vscode",
+  "request": "attach",
+  "program": "/tmp/a.out",
+  "waitFor": true
+}
+```
+
+This will work as long as the architecture, vendor and OS supports waiting
+for processes. Currently MacOS is the only platform that supports this.
+
+
+### Loading a Core File
+
+Loading a core file can use the `"attach"` request along with the
+`"attachCommands"` to implement a custom attach:
+
+```javascript
+{
+  "name": "Attach to Name (wait)",
+  "type": "lldb-vscode",
+  "request": "attach",
+  "attachCommands": ["target create -c /path/to/123.core /path/to/executable"],
+}
+```
