Added support for getlogin(); does *not* use getlogin_r() where
available since the interface is poorly defined on at least one major platform (Solaris). Moved table of constant names for fpathconf() & pathconf() into the conditional that defines the conv_path_confname() helper; Mark Hammond reported that defining the table when none of the constants were defined causes the compiler to complain (won't allow 0-length array, imagine that!). In posix_fpathconf(), use conv_path_confname() as the O& conversion function, instead of the conv_confname() helper, which has the wrong signature (posix_pathconf() already used the right thing).
