Clear event watchers before invoking connection callback

This lets a socket remain "Idle" without receiving readability events.
Useful for an immediately-released connmgr socket

select: fixup timers

This commit adapts a timer model similar to what is used in IOCP

select: don't embed fd_set inside iops structure

we only use it inside the loop, so this can be a loop-local variable

Add 'counted' list which maintains size

This makes it easier to track the number of items within a list without
maintaining an external counter

transfer_socket: Don't perform checks if to==from

We should return when we detect the connections are idential, as the
assertions are only for actual transfers

Connmgr fixups

- Replace list+explicit counter with new 'clist'
- Replace timer_create/destroy with rearm/disarm
- Added dump function to print pool state to stderr
- Added 'lcb_async_signal' and 'lcb_async_cancel' to timer.h

Increase efficiency for connection pools

This commit attempts to be a bit more judicious about how sockets are
released back to the pool. This is important in rebalance scenarios
where the configuration changes frequently and server structures are
created and destroyed.

The notable changes are:

- Don't use apply_want for READ_EVENT if we have nothing to read
- Fix up some bugs in the CCCP provider which cause it to stall, release
  a bad socket, or not acquire a proper socket
- Fix up bugs in server_io.c where it would release a timed-out socket

Re-organize CMakeLists

The goal here is to make our code and build system more modular, with
the ultimate aim of being able to -theoretically- ship some components
as being standalone.

The first step is trying to untangle the build process - where multiple
modules can be built independently into shared or static archives and
then linked ultimately into their resultant objects.

The second step is to eliminate the NMakefile

Currently supported:

- Plugin builds (libev, libuv, libevent)
- Tools (cbc, pillowfight)
- Tests (unit-test, smoke-test, check-all)
- SOVERSION
- DLL Version information
- config.h generation
- Fat binary builds (OS X)
- Maintainer mode

TODO:

- Make things completely out of tree. Currently the configuration.h
  header is still being generated inside the tree
- Better facilities for downloading the mock server
- Create source tarballs
- Create windows zipfiles and/or installers
