Temporarily disable async-io tests 
These will fail until a new version of polling is released and async-io
is updated.

Separate adding and modifying of file descriptors 
This replaces Poller.insert() and Poller.interest() with Poller.add()
and Poller.modify(), and renames Poller.remove() to Poller.delete().

The method Poller.add() is used for adding a new file descriptor, while
Poller.modify() is used for updating an existing one. Poller.remove() is
renamed to Poller.delete() so the naming scheme of these methods follows
that of epoll, wepoll, etc.

This new setup means that adding a new socket only requires a single
call of Poller.add(), instead of a combination of Poller.insert() and
Poller.interest(). This reduces the amount of system calls necessary,
and leads to a more pleasant API.

On systems that use kqueue or ports, the behaviour of Poller.add() and
Poller.modify() is the same. This is because on these systems adding an
already existing file descriptor will just update its configuration.
This however is an implementation detail and should not be relied upon
by users.

Migrating to this new API is pretty simple, simply replace this:

    poller.insert(&socket);
    poller.interest(&socket, event);

With this:

    poller.add(&socket, event);

And for cases where Poller.interest() was used for updating an existing
file descriptor, simply replace it will a call to Poller.modify().

Don't automatically make descriptors non-blocking 
This adds redundant system call overhead for file descriptors which have
already been turned into non-blocking file descriptors. In addition, the
polling crate doesn't need to implement platform specific code for
enabling non-blocking mode. Instead, users of polling can do so using
(for example) standard library methods such as
TcpListener.set_nonblocking().

See https://github.com/stjepang/polling/issues/16 for more information.

Check if `epoll_create1` is implemented by its error code

oblique 62103c1ef0 Check if `epoll_create1` is implemented by its error code 
If binary is statically linked to libc then `libc::dlsym`
will always return `NULL`. This is the case when a target
with musl is used.

To fix this we check if error code of `epoll_create1` is `ENOSYS`.
