Improve GNU readline compat, patch by Steve Tell in 1997 and 1998

Browse Source 
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.
