tio: update to 1.33.

Changes since tio v1.32:

* Show auto connect status in show configuration

* Use '#pragma once' in all headers

* Improve printed output

  Get rid of inconsistencies in the printed output (error printing,
  colors, etc.).

  Prepare for user configurable color.

* Rename option -i to -L

* Shorten timestamp

* Shorten timestamp description

  We do not need the date part of the timestamp. It simply takes up too
  much precious line space. In case of logging to file, one can easily
  conclude the date from the file date information.

* Replace Travis with circleCI

* Replace autotools with meson

  To introduce much simpler build configuration which is also easier to
  maintain.

* Add list serial devices feature

  For convenience, add a --list-devices option which lists the available
  serial devices.

* Cleanup: Use dot notation for default options struct

* Update AUTHORS

* Add command to show version

  The key sequence ctrl-t v will now show the version of tio.

* Align format of timestamps

* Add Sylvain as official co-maintainer

Sylvain LAFRASSE:

* Add '-t' option description for time stamping.

* Add description for time stamping.

* Resolved tio/tio#84: Added timestamps in log file if enabled.

attila-v:

* Refine timestamps with milliseconds and ISO-8601 format (#129).

  * Show milliseconds too in the timestamp (#114) and log file (#124)
  * Change timestamp format to ISO-8601.

Yin Fengwei:

* Output newline on stdout with hex print mode

  This is to fix the issue #104. The timestamp will always be
  printed at the beginning of line:

  [10:25:56] Switched to hexadecimal mode
  0d 0a 0d [10:25:57] 41 43 52 4e 3a 5c 3e 0d 0a 0d [10:25:58] 41

  is changed to:

  [12:34:56] 45 72 72 6f 72 3a 20 49 6e 76 61 6c 69 64 20
  [12:34:56] 41 43 52 4e 3a 5c 3e
  [12:34:56] 41 43 52 4e 3a 5c 3e
  [12:34:57] 41 43 52 4e 3a 5c 3e 6c 73

Jakob Haufe:

* Make comparison POSIX compliant

  String comparison with == is not POSIX compliant and can fail with e.g.
  dash.

Henrik Brix Andersen:

* Add bash completion of tty devices.

* Add -t/--timestamp to bash completion script.

Henner Zeller:

* Local echo: show character by character even if stdout buffered.

Bj旦rn Stenberg:

* Show error when failing to open a tty

Alban Bedel:

* Fix out of tree builds

  Out of tree builds are currently broken because $(top_srcdir)src/include
  is not in the search path. In tree builds are working because autconf add
  $(top_builddir)/src/include to the search path for the generated config.h.
  As $(top_builddir) and $(top_srcdir) are identical during in tree builds
  the search path still end up beeing somehow correct.

  To fix this add -I$(srcdir)/include to the CPPFLAGS in Makefile.am.

Fabrice Fontaine:

* src/setspeed2.c: fix redefinition of termio

  Include ioctls.h and termbits.h from asm-generic instead of asm to avoid
  build failures.

Erik Moqvist

* Exit if output speed cannot be set.

Lars Kellogg-Stedman:

* fflush() after putchar() for print_hex and print_normal

  In order for local echo to work properly, we have to either call
  fflush(stdout) after every character or just disable line buffering.
  This change calls fflush() after putchar().

* Disable line buffering in stdout

  In order for local echo to work properly, we have to either call
  fflush(stdout) after every character or just disable line buffering.
  This change uses setbuf(stdout, NULL) to do the latter.

George Stark:

* dont show line state if ioctl failed

* add serial lines manual control

arichi:

* Flush every local echo char

  Flush stdout at every char in case it
  happens to be buffered.

Mariusz Midor:

* Newline: handle booth NL and CR

  Flag ONLCRNL expects code \n after press Enter, but on some systems \r
  is send instead.
