[asiofix] imported a bug fix in ASIO 1.5.1:

https://sourceforge.net/projects/asio/files/asio/1.5.1%20%28Development%29/
* Fixed a bug on kqueue-based platforms, where reactor read operations that return false from their perform() function are not correctly re-registered with kqueue.
This is necessary for multiple processes sharing the same socket to both
accept queries.
