This changeset adds support for: * rl_prep_terminal(), * rl_deprep_terminal(), both of which are only wrappers to rl_ttyset(). * rl_getc() and: * (*rl_getc_function), defaults to rl_getc() * (*rl_event_hook) * (*rl_prep_term_function), defaults to rl_prep_terminal() * (*rl_deprep_term_function), defaults to rl_deprep_terminal() For further details, see http://www.cs.unc.edu/~tell/dist/magic-readline.README Differences from Steve's commit include: signal safety in rl_getc(), restart read() on EINTR, and make sure to support "int meta_flag" to rl_prep_terminal() which is the GNU syntax. To that end I reused the inverse of rl_meta_chars.
