David Wilson 7ff4e6694c issue #536: rework how 2.3-compatible simplejson is served
Regardless of the version of simplejson loaded in the master, load up
the ModuleResponder cache with our 2.4-compatible version.

To cope with simplejson being loaded due to modules like ec2_group that
try to import it before importing 'json', also update target.py to
remove it from the whitelist if a local 'json' module import succeeds.

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 be6ab52fe1 issue #488: fix shutdown damage caused in 6ca2677de5
os._exit() subverted calm shutdown, meaning unix.Listener never had a
chance to cleanup its socket.

Move unix.Listener socket cleanup into its class so it is automatic
during shutdown, rather than cutpasted for each consumer.

Disable the watcher thread in the MuxProcess, it is useless.

Add .sock extension to /tmp/mitogen_unix_*, so we can write a test.

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.

David Wilson 8f5b65f7ec issue #477: introduce subprocess isolation.
Since Python 2.4 fork is so defective, we must use subprocesses for
mitogen_task_isolation=fork. This has plenty of upside, since the long
term goal is to dump forking altogether. This allows a gentle
introduction of its replacement.
