strread.m: Make m-file a legacy function. * NEWS: Announce change. * scripts/legacy/module.mk, scripts/io/module.mk: Move findstr.m from io/ dir to legacy/ dir. * strread.m: Add Octave:legacy-function warning at top of function. Change docstring to note that this function is obsolete. Add an initial BIST test to trigger legacy-function warning which is then suppressed. * debug.cc (Fdbstop): Change documentation to use an example in axis.m rather than strread.m * textread.m: Turn off Octave:legacy-function warning locally before calling strread.
