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%)

parent: pre-cache bootstrap if possible.

When the interpreter is modern enough, use zlib.compressobj() to
pre-compress the unchanging parts of the bootstrap once, then use
compressobj.copy() to append just the context's config during stream
construction.
Before: 100 loops, best of 3: 5.81 msec per loop
After: 10000 loops, best of 3: 35.9 usec per loop
With 100 targets this is enough to knock 6 seconds off startup, at 500
targets it becomes half a minute.
Test 'program':
python -m timeit -s '

s=p.Stream(r, 0, max_message_size=1);
