String buffer argument like IO#read and IO#read_nonblock to reduce
GC overhead

* Socket and I/O related improvements
* Socket and I/O-related improvements
* All non-blocking I/O (including socket) methods allow
`exception: false' to suppress expensive and noisy exceptions
in common usage. Feature #10532 [Feature #11229]
* Calling overhead of most of these keyword-using I/O methods is
reduced by avoiding the inefficient C API to parse keywords.
[Feature #11339]
* Calling overhead of most of new keyword-using I/O methods in
[Feature #11229] is reduced by avoiding the inefficient C API
to parse keywords. [Feature #11339]
* The standard library is updated to use the improved
exception-free non-blocking I/O. This has the additional
benefit of quieter $DEBUG output in addition to reducing expensive
exceptions. [Feature #11044]
* The Socket#recv* methods allow an optional destination
buffer to reduce GC pressure, based on the existing behavior
of IO#read* methods. [Feature #11242]
exception-free non-blocking I/O from [Feature #11229].
This has the additional benefit of quieter $DEBUG output in
addition to reducing expensive exceptions. [Feature #11044]
* (Linux-only) waiting on a single FD anywhere in the stdlib no longer
uses select(2), making it immune to slowdowns with high-numbered FDs.
