maint: Rename instances of LS_ASCII to LS_TEXT for clarity. Octave's default save format is '-text' which is confusingly referred to in the code base as LS_ASCII (looks like '-ascii' mode). * ls-oct-text.cc, ls-oct-text.h: Renamed from ls-oct-ascii.[cc|h]. * ls-oct-ascii.cc, ls-oct-ascii.h: Removed files. * libinterp/corefcn/module.mk: Add ls-oct-text.cc, ls-oct-text.h to build system. * load-save.h (load_save_format_type): Change first value of enum from LS_ASCII to LS_TEXT. * load-save.cc: Rename instances of LS_ASCII to LS_TEXT. Rename instances of read_ascii_data to read_text_data. * ov-base-diag.cc, ov-base-int.cc, ov-base-sparse.cc, ov-bool-mat.cc, ov-bool.cc, ov-complex.cc, ov-cx-mat.cc ov-fcn-inline.cc, ov-float.cc, ov-flt-complex.cc, ov-flt-cx-mat.cc, ov-flt-re-mat.cc, ov-int16.cc, ov-int32.cc, ov-int64.cc, ov-int8.cc, ov-perm.cc, ov-re-mat.cc, ov-scalar.cc, ov-str-mat.cc, ov-uint16.cc, ov-uint32.cc, ov-uint64.cc, ov-uint8.cc: Use '#include "ls-oct-text.h"' rather than ls-oct-ascii.h. ov-cell.cc, ov-class.cc, ov-fcn-handle.cc, ov-lazy-idx.cc, ov-struct.cc: Use '#include "ls-oct-text.h"' rather than ls-oct-ascii.h. Rename save_ascii_data to save_text_data, read_ascii_data to read_text_data.
