Introduce new I/O errors and enhanced it implementation
Instead of a single I/O error type IoError introduced new errors
WriteError, ReadError and ResourceError.
WriteError - occurs when a write operation is failed.
ReadError - occurs when a read operation is failed.
ResourceError - is a critical error. Occur when the operation is the
I/O in a non-existent or invalid device handle. Also, this error
indicates the sudden removal of the device from the system,
for example, when pulled out already open USB/Serial converter.
When an ResourceError occurs the user must close the device by close()
method, otherwise it will lead to an infinite trigger a I/O notifiers
(at least on *nix platform).
Checked on Windows and Linux with USB/Serial PL2303 converter.
