Fixed any exposed bugs across the stack.

Add a poll() based implementation. Heavily leverages pollset infrastructure to allow small polls to be the norm. Exposes a mechanism to plug in epoll/kqueue for platforms where we have them.

Simplify iomgr callbacks to return one bit of success or failure (instead of the multi valued result that was mostly unused previously). This will ease the burden on new implementations, and the previous system provided no real value anyway.

Removed timeouts on endpoint read/write routines. This simplifies porting burden by providing a more orthogonal interface, and the functionality can always be replicated when desired by using an alarm combined with endpoint_shutdown. I'm fairly certain we ended up with this interface because it was convenient to do from libevent.

Things that need attention still:
- adding an fd to a pollset is O(n^2) - but this is probably ok given that we'll not
use this for multipolling once platform specific implementations are added.
- we rely on the backup poller too often - especially for SSL handshakes and for client
connection establishment we should have a better mechanism ([] []
- Linux needs to use epoll for multiple fds, FreeBSD variants (including
Darwin) need to use kqueue. ([] []
- Linux needs to use eventfd for poll kicking. ([]

Previously, this alway generated a service file with a header.

However, this does not work well, it means whenver the ruby service plugin is
used, every proto file ends up with a service file.

This causes get_unused_port_or_die to try different port numbers in each
concurrently running tests, and consequently enables some parallelism of test
processes.

SurfaceActiveCall.php was split into four files. Each file must contain exactly one PHP class because of the following line in the spec:

> The terminating class name corresponds to a file name ending in .php. The file name MUST match the case of the terminating class name.

Other changes were made to correctly import the library using the autoloader.
