and sendfile methods that I/O layers can use. _PR_EmulateAcceptRead
is superseded by PR_EmulateAcceptRead, and _PR_EmulateSendFile and
_PR_UnixSendFile are superseded by PR_EmulateSendFile. Deleted unused
function _PR_HPUXTransmitFile. The workaround for the OSF1 V4.0

ifdef'd with the new macro OSF1V4_MAP_PRIVATE_BUG, which is defined
only on OSF1 V4.
