* _check_resolved_address() is implemented with getaddrinfo() which is slow
* If available, use socket.inet_pton() instead of socket.getaddrinfo(), because
  it is much faster

Microbenchmark (timeit) on Fedora 21 (Python 3.4, Linux 3.17, glibc 2.20) to
validate the IPV4 address "127.0.0.1" or the IPv6 address "::1":

* getaddrinfo() 10.4 usec per loop
* inet_pton(): 0.285 usec per loop

On glibc older than 2.14, getaddrinfo() always requests the list of all local
IP addresses to the kernel (using a NETLINK socket). getaddrinfo() has other
known issues, it's better to avoid it when it is possible.

Just try to be consistent: _debug was already used in some places, and always
used in BaseProactorEventLoop.

interpreter under test is being run in an environment that requires the use of
environment variables such as PYTHONHOME in order to function at all.

Adds a test.script_helper.interpreter_requires_environment() function
to be used with @unittest.skipIf on stdlib test methods requiring this.

and array_buffer_getbuf().

It was expected that string_size == PyBytes_GET_SIZE(buf) if the buffer is
shared, but truncate() and __setstate__() can set string_size without
unsharing the buffer.

Issue 23359:  Reduce size of code in set_lookkey. Only do linear probes when there is no wrap-around.

Nice simplification contributed by Serhiy Storchaka :-)

and bytearray_getbuffer().  Both functions now raise BufferError in that
case.
