    errno: add POSIX error codes EMSGSIZE, ECONNREFUSED to the ABI
    
    EMSGSIZE: Argo's sendv operation will return EMSGSIZE when an excess amount
    of data, across all iovs, has been supplied, exceeding either the statically
    configured maximum size of a transmittable message, or the (variable) size
    of the ring registered by the destination domain.
    
    ECONNREFUSED: Argo's register operation will return ECONNREFUSED if a ring
    is being registered to communicate with a specific remote domain that does
    exist but is not argo-enabled.
    
    These codes are described by POSIX here:
    http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/errno.h.html
        EMSGSIZE     : "Message too large"
        ECONNREFUSED : "Connection refused".
    
    The numeric values assigned to each are taken from Linux, as is the case
    for the existing error codes.
        EMSGSIZE     : 90
        ECONNREFUSED : 111
