cf8f4d1818 To simplify the user's error interface always use LIBSSH2_ERROR_EAGAIN.
LIBSSH2CHANNEL_EAGAIN and LIBSSH2SFTP_EAGAIN are still valid, but are
defined as LIBSSH2_ERROR_EAGAIN.

7d57222912 Finish making SFTP fully non-blocking capable.
Functions that return an "int", and friends, return LIBSSH2SFTP_EAGAIN.
Functions that return a structure return NULL and set the error to
LIBSSH2_ERROR_EAGAIN

4b8db8c1ab Modify the code to truely support non-blocking. Propogate the EAGAIN error
all the way up to the user interface.  All code modules bug sftp.c have
been completed.

Functions that return an "int", or similar return LIBSSH2CHANNEL_EAGAIN to
indicate some part of the call would block, in non-blocking mode.

Functions that return a structure, like "LIBSSH2_CHANNEL *", return NULL
and set the libssh2 error.  The error can be obtained with either
libssh2_session_last_error() or libssh2_session_last_errno().  Either of
these will return the error code of LIBSSH2_ERROR_EAGAIN if the
call would block, in non-blocking mode.

The current state of a function and some variable are keep in the
structures so that on the next call the operation that would block can
be retried again with the same data.

9d55db6501 Adding src/transport.c for the SECSH transport layer read/write in a non-
blocking way. The channel code is now responsible for enabling/disabling
blocking status and to work with it.

I've also modified indenting and fixed compiler warnings at places, and
added a bunch of new examples in example/simple that I've used to verify that
the code still runs like before.

libssh2_channel_{read|write}nb_ex() and libssh2_sftp_{read|write}nb() are the
four new functions that supposedly work non-blocking.
