getaddrinfo takes an exclusive lock on some platforms, causing clients to queue
up waiting for the lock if many names are being resolved concurrently. Users
may want to handle name resolution in their own code, for the sake of caching,
using an alternate resolver, or to measure DNS duration separately from
connection duration. Skip getaddrinfo if the "host" passed into
create_connection is already resolved.

The OS X buildbots were failing at the second setrlimit() call with EPERM, as
if they were trying to raise the hard limit. The call should be keeping the
hard limit the same and raising the soft limit back to its original value, so
I don't understand the failure.

Before the argparse conversion, compileall would (sometimes) accept multiple
paths when -d was specified.  Afterward, it does not.  The corresponding check
in the original code claimed to prevent multiple *directories* from being
specified...but it didn't really work even to do that.  So this patch fixes
the regression by invoking the consenting adults rule: if you specify a
combination of arguments to compileall that produces files with inconsistent
destdirs (which you could do before), it is on you.

Previous documentation was not clear if the geturl(), info() and getcode()
were valid for HTTP responses. The “msg” attribute is different to the usual
HTTPResponse.msg attribute. Based on patch by Evens Fortuné.
