David Wilson d4c0250083 issue #532: PushFileService race.
There has always been a race in PushFileService since given a parent
asked to forward modules to two children via some intermediary:

    interm = router.local()
    c1 = router.local(via=interm)
    c2 = router.local(via=interm)

    service.propagate_to(c1, 'foo/bar.py')
    service.propagate_to(c2, 'foo/bar.py')

Two calls will be emitted to 'interm':

    PushFileService.store_and_forward(c1, 'foo/bar.py', [blob])
    PushFileService.store(c2, 'foo/bar.py')

Which will be processed in-order up to the point where service pool
threads in 'interm' are woken to process the message.

While it is guaranteed store_and_forward() will be processed first, no
guarantee existed that its assigned pool thread would wake and take
_lock first, thus it was possible for forward() to win the race, and for
a request to arrive to forward a file that had not been placed in local
cache yet.

Here we get rid of SerializedInvoker entirely, as it is partially to
blame for hiding the race: SerializedInvoker can only ensure no two
messages are processed simultaneously, it cannot ensure the messages are
processed in their intended order.

Instead, teach forward() that it may be called before
store_and_forward(), and if that is the case, to place the forward
request on to _waiters alongside any local threads blocked in get().

David Wilson 86f9572ef7 issue #536: stop defining explicit localhost in inventory.
This was needed at some point in the past, but the tests don't seem to
care about it any more. We'll fix any CI breakage by changing the tests,
since verifying implicit localhost behaviour is important.

David Wilson 0e193c223c issue #508: master: minify all Mitogen/ansible_mitogen sources.
Minify-safe files are marked with a magical "# !mitogen: minify_safe"
comment anywhere in the file, which activates the minifier. The result
is naturally cached by ModuleResponder, therefore lru_cache is gone too.

Given:

    import os, mitogen
    @mitogen.main()
    def main(router):
        c = router.ssh(hostname='k3')
        c.call(os.getpid)
        router.sudo(via=c)

SSH footprint drops from 56.2 KiB to 42.75 KiB (-23.9%)
Ansible "shell: hostname" drops 149.26 KiB to 117.42 KiB (-21.3%)

David Wilson 599da0689a issue #477 / ansible: avoid a race in async job startup.
Ansible 2.3/Python 2.4 work revealed there is no guarantee a slow target
will have written the initial job status file out before a fast
controller makes an initial check for it. Therefore, provide AsyncRunner
with a sender it should send a message to when the initial job file has
been written.

As a bonus, also catch and report exceptions happening early in
AsyncRunner, rather than leaving them to end up in -vvv output.
