Added new typedef for the Resolve function. The Resolve function is a
std::function accepting corresponding parameters. When it's invoked it
will send the reply immediately. Users can still wrap it in a
MozPromise if they want promise chaining.
The original typedef of the Promise type is repurposed as the Send*
functions' return type.

This patch implements async returns for IPDL using MozPromises. There
are following changes:
* Initialize AbstractThreads for MessageLoops
* Record promises and their reject functions
* When async message returns, call their resolve functions
* When send error or channel close, call their reject functions
* Implement "unresolved-ipc-promises" count for about:memory
* Test cases
See bug attachment for generated code from test cases

An IPDL unit test that is intended to fail should check that the
reason the test fails matches the expected reason for failure. We have
had a number of cases where some change, like renaming a keyword,
causes tests to start failing for the wrong reason, which means they
are no longer testing anything useful.
To support this, each file in error/ must contain one or more error
annotations. An error annotation is a line starting with "//error:",
followed by whatever the rest of the expected error is. For every one
of these annotations that a file has, the stderr output of compiling
the test must contain the specified string, including the "error:". It
is also an error for an error/ file to not contain an error
annotation.
To generate the initial set of annotations, I just copied and pasted
the error that each test produced. I did some light auditing to check
that the errors are reasonable, which did turn up one minor error
which I fixed as part of bug 1347527.
This patch does not check that every error produced by compiling the
file is in the list of expected errors. I think that's less of a
problem if it does occur.

Adding this unused message prevents a compiler warning
about the private field mState being unused.
Also, get rid of some trailing whitespace.

This just wraps all the XRE method calls to go through the Bootstrap API

The state machine stuff provides a decent compact overview of where
races are supposed to happen, so I just commented them out.

With the removal of state machines, the state() method is no longer
supported, so these assertions must be removed.

The uses of state() in TestHangs and TestStackHooks only have two
states, depending on how many times the method has been called.
Two uses of state() have to be fixed in TestLatency. Each waits for 5
messages, then resets the state and sends replies.

The parent process crashes if it gets a bad message from the child,
but that makes it hard to test. This patch overrides the fatal error
handling method and uses the old behavior, that kills the child.
I copied the code to kill the child from TestHangs.

immediately with a syntax error.
shmem_access_union.ipdl: Remove this test, which involves the
semi-removed ACL feature for shmem.

multimanNonexistentMgrs.ipdl: Make the name of the protocol match the
