David Wilson 48351a1889 issue #155: parent: support Context.shutdown(), reap children on exit.
This permits graceful shutdown of individual contexts, without tearing
down everything.

Update mitogen.parent.Stream to also wait for the child to exit, to
prevent the buildup of zombie processes. This introduces a blocking wait
for process exit on the Broker thread, let's see if we can get away with
it. Chances are reasonable that it'll cause needless hangs on heavily
loaded machines.

David Wilson 6a74edce6b issue #155: parent: move master.Context into parent.
The Context and Router APIs for constructing children and making
function calls should be available in every parent context, as user code

David Wilson 54ff1c90fa issue #155: add DEL_ROUTE, propagate ADD_ROUTE upwards
* IDs are allocated by the parent responsible for contructing a new
  child, using ALLOCATE_ID to the master as necessary to allocate new ID
  ranges.

* ADD_ROUTE is sent up the tree rather than down. This permits
  construction of the new context to complete concurrent to parent
  contexts learning about its existence. Since all streams are strictly
  ordered, it's not possible for any parent to observe messages from the
  new context prior to arrival of an ADD_ROUTE from the parent notifying
  of its existence.

  If the new context, for example, implements an Ansible async task, its
  parent can start executing that without waiting for any synchronous
  confirmation from any parent or the master.

* Since routes propagate up, it's no longer possible for a plain
  non-parent child to ever receive ADD_ROUTE, so that code can be moved
  out of core.py and into parent.py (-0.2kb compressed).

* Add a .routes attribute to parent.Stream, and respond to disconnection
  signal on the stream by propagating DEL_ROUTE for any ADD_ROUTE ever
  received from that stream.

* Centralize route management in a new parent.RouteMonitor class

David Wilson 20f5d89dfa issue #156: fix several more races
* Don't need to sleep if queue>sleepers, can just pop the right queue
  element and return it.

* If queue>sleeping and waking==sleeping, no mechanism existed to ensure
  a thread newly added to sleeping would ever be woken. Above change
  fixes that.

* Cannot trust select() return value, scheduler might sleep us
  indefinitely while put() writes a byte.

* Sleeping threads didn't pop FIFO, they popped in whatever order
  scheduler woke them up. Must recover index and use it to pick the pop
  index.

David Wilson bdd8648bae ssh: enable compression by default
Using the same test as in 7af97c0365,
transmitted wire bytes drops from 135,531 to 133,071 (-1.81%), while
received drops from 21,073 to 14,775 (-30%).

Combined, both changes shave 13,914 bytes (-8.6%) off aggregate
bandwidth usage.

Make it configurable as compression hurts in some scenarios.

David Wilson 4d940f08ae importer: drop redundant prefix from pkg_present
For the 52 submodules of ansible.modules.system, this produced a 1602
byte pkg_present list. After stripping it becomes 406 bytes, and the
entire LOAD_MODULE size drops from 1988 bytes to 792 bytes (-60%).

For the 68 submodules of ansible.module_utils, 1902 bytes pkg_present
becomes 474 bytes (-75%), and LOAD_MODULE size drops from 2867 bytes to
1439 bytes (-49%).

In a simple test running Ansible's "setup" module followed by its "apt"
module, wire bytes sent drops from 140,357 to 135,531 (-3.4%).

David Wilson 20afa5b90c Latch v2: combined queue + one self-pipe-per-thread
Turns out it is far too easy to burn through available file descriptors,
so try something else: self-pipes are per thread, and only temporarily
associated with a Lack that wishes to sleep.

Reduce pointless locking by giving Latch its own queue, and removing
Queue.Queue() use in some places.

Temporarily undo merging of of Waker and Latch, let's do this one step
at a time.
