On some platform such as VMware ESXi, DefaultSelector fails
to detect selector due to default value.
This fix adds a check and uses the correct selector depending upon
select implementation and actual call.

* #30014: make selectors.DefaultSelector.modify() faster by relying on selector's modify() method instead of un/register()ing the fd
* #30014: add unit test
* speedup poll/epoll/devpoll modify() method by using internal modify() call
* update doc
* address PR comments
* update NEWS entries
* use != instead of 'is not'
* #30014: refactor poll-related classes so that poll(), epoll() and devpoll() share the same methods for register(), unregister(), close() and select()
* remove unused attribute
* use specific class attributes instead of select.* constants
* have all classes except SelectSelector a _selector attribute
* BaseException -> Exception
* be explicit in defining a close() method only for selectors which have it
* fix AttributeError
timeout when interrupted by a signal, except if the signal handler raises an
exception. This change is part of the PEP 475.
The asyncore and selectors module doesn't catch the InterruptedError exception
anymore when calling select.select(), since this function should not raise
InterruptedError anymore.
RuntimeError if the selector is closed. And selectors.BaseSelector.close() now
clears its internal reference to the selector mapping to break a reference
cycle. Initial patch written by Martin Richard.
