Python type docs. While we're here, we also clean up formatting of code
samples.

People often seek to learn how mach commands work. A common way to do
this is to launch a debugger and step through the code as it is
executing. But this requires someone to first find and modify the mach
command. This involves overhead.
This patch adds a global --debug-command argument to mach. When present,
we launch an interactive debugger right before command dispatch. This
allows people to easily enter a debugger to see what mach commands are
doing, hopefully lowering the barrier to understanding and contributing.

The reason to use '+' prefixing was to distinguish between options to the
mach command itself, and options that are passed down to whatever the
command does (like mach run passing down args to the built application).
That makes things unnecessarily awkward, and quite non-standard.
Instead, use standard '-' prefixing, and pass all the unknown arguments
down. If there is overlap between the known arguments and arguments supported
by the underlying tool (like -remote when using mach run), it is possible to
use '--' to mark all following arguments as being targetted at the underlying
tool.
For instance:
mach run -- -remote something
would run
firefox -remote something
while
mach run -remote something
would run
firefox something
As allow_all_arguments is redundant with the presence of a argparse.REMAINDER
CommandArgument, allow_all_arguments is removed. The only mach command with a
argparse.REMAINDER CommandArgument without allow_all_arguments was "mach dmd",
and it did so because it didn't want to use '+' prefixes.
While I was here, I removed the try..except in favor of failing fast.
Before, we were only making cosmetic changes. Now, we actually need the
group for mach to work. It makes sense to stop ignoring errors.
This fixes a regression from d53d1c6cdf13 / bug 951733.

We now return the status code from executed processes. The API to
require a successful status code has been changed from ignore_errors to
ensure_exit_code. The build mach command no longer spews a stack trace
if make fails.

Previously we were tighly coupled with MozbuildObject. This was not in
the spirit of mach being a generic tool. Now, instead of passing multiple
arguments to __init__ of the class providing the mach command we either
pass 0 or 1. The number of arguments is detected when processing the
@CommandProvider decorator. The optional argument is a named tuple
containing mach run-time state.
Capturing of mach command provider information is now captured in a
class (as opposed to an anoymous tuple). We also capture these in a rich
data structure which is passed as part of the run-time data to the
command provider class. This allows mach commands to inspect the mach
environment.
Mach decorators have been moved to mach.decorators. mach.base is
reserved for generic mach data/container classes.
Existing mach command classes derived from MozbuildObject have been
replaced with either object or mozbuild.base.MachCommandBase. This
latter class translates the mach context instance passed to __init__
into the constructor arguments for MozbuildObject.__init__.
Support for registering function handlers with mach has been removed.
All handlers must be inside classes.

This is meant to be a stop-gap until more robust tree building lands in
mozbuild. It simply proxies building through client.mk and captures
compiler warnings using the existing mechanism in mozbuild.
There are some DRY violations for how the compiler database is managed.
The more robust tree building code contains consolidated compiler
database logic. The DRY violations should disappear when that lands.
