This change pulls out a separate pollset_kick module, which currently
uses a freelist of pipes dynamically assigned to pollsets when they
enter polling rather than the previous racy sharding mechanism.
We ultimately may wish to eliminate the dynamic assignment for multipoll
sets, but this should be sufficient for the moment.
Allows servers to expedite shutdown once all in-progress calls are
completed. We may want to eventually remove grpc_server_shutdown in
preference to this.
The source code of the libraries depends on openssl being built, as it will setup the headers.
Since we don't know exactly which source depends on openssl (we could start flagging it in build.json, but that'd be painful), we just flag all the source for every ssl-enabled library to depend on openssl being built.
This was working so far because of GNU make's magic that automatically finds the sources depending on its output, and not on its input.
This also explains why running "make" would always rebuild the plugins: because GNU make think some dependencies are phony and aren't there.
If we don't have a .o, we don't need dependencies, so skip the setup
step of building them. Instead, when building the .o, we generate the
.dep and output it (to objs/ to make the rules a little easier). The
next run of make will include the dep file and any dependencies will be
picked up.
This change also disables the disabling of dependency checking if we
have zlib or openssl being compiled from third_party. Additionally it
inverts the logic for including dependencies from ONLY if we are doing a
clean to ONLY if we are NOT doing a clean.
Checked that the opensource version still builds.
Just addressing core for now. We will do c++ later.

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. ([]
