fix build on windows

Better socket kick for Windows.

Adding a handler for abort().

Let's ignore our generated cache.mk from git.

Now calling tcp_shutdown will in fact close the socket, which cascades into properly cleaning out all the pending requests.
The tcp_server_windows's shutdown logic had to be rewritted (simplified) in order to take this into account.

We want to have a chance to debug a call to abort() in case we have a debugger attached.

This code branches out of the alpha/early_adopter code and begins
building toward the beta API.

Install simple Windows exception handlers.

Filtering stdout for JUnit report in case of timeouts.
