020f40693a line editing: add an option to emit ESC [ 6 n and use results
This makes line editing able to recognize case when
cursor was not at the beginning of the line. It may also
be adapted later to find out display size (serial line users
would love it).

5e34ff29bc *: mass renaming of USE_XXXX to IF_XXXX
and SKIP_XXXX to IF_NOT_XXXX - the second one was especially
badly named. It was not skipping anything!

7960ea8918 Confirmed that on Linux the serial interrupt takes precedence over the timer
interrupt, so we don't need to worry about scheduler delays.  This means the
delay can be trimmed down to 25 miliseconds.  Add comment while at it.

5e38cd910a Escape sequences sent over serial links don't come in as a block, so poll
needs to pause a bit to make sure the next character has time to come in.

988dd5549b Clean up editors/vi.c:readit() so it only does readahead when actually
parsing an escape sequence.  (This mitigates but doesn't fully fix the
the "cursoring around the file deletes data under qemu" bug, presumably due
to "\033[D" being treated as three separate characters.)

2724fa9d8a remove alarm() calls which were functioning as a primitive
watchdog function, presumably to catch infinite loop bugs. 
(control-C can do the same thing, and the alarms were too short in
any case.)  also, switch to sigsetjmp/siglongjmp in order to allow
repeated use of control-C -- otherwise it works once, then not again.

35e9c5d83a fixups to vi usage, and move the initial redraw() past the

c51fc7bed6 fixed the "dot" (i.e. '.') command, to properly re-init its
buffer between commands, not recalculate its length all the time,
and to not reallocate its fixed-length buffer frequently.

fixed the 'c', 'd', and 'y' commands to properly handle both motions
that are just part of a line, and those that are multiline.  for
instance, now "c%" and "2cw" work correctly, whether the motions span
lines or not.

added some permissble motions for 'c', 'd', and 'y':  namely 'h',
'l', SPACE, BS, and DEL

eaabf0675f vi: multiple fixes by Natanael Copa <natanael.copa@gmail.com>
* the puzzling message on error is replaced with strerror(errno)
  so it should be even more detailed and smaller at the same time.
* merged code in edit_file() and code for ':edit <file>' in colon() into
  new func init_text_buffer(). Was horribly duplicate. Moved most of
  error/sanity checking to file_insert(). Result is that you get a proper
  validation (prevent reading /dev/*) and error messages for ':r <file>' 
* renamed 'cfn' to 'current_filename' for improved readability
* merged smallint vi_readonly and readonly into bitfields into
  readonly_mode to save space.
* added text_size variable to keep track how big the text buffer is.
  This is used to fix a buffer overflow. To reproduce bug:
  ./busybox vi TODO
  :r Makefile
  vi segfaults due to no buffer checking is done at all. som redesign is
  needed here but i added a check in text_hole_make() to aviod the
  segfault at least.
* removed isblnk() and use isblank(3) instead.
* fixed compiler warning by displaying the return code for :!<command>
  This makes things bigger than needed but since the patch reduces the
  overall size... (see below)
* new func next_tabstop(int) merges some duplicate code. There are more
  cuplicode here but i couldnt find a good way to merge them.
* Fix *ANNOYING* placement of cursor on '\t' characters. To reproduce:
    echo -e "\thello" > file1
    ./busybox vi file1
  Try to insert some text at the beginning of line. Text will be inserted
  but cursor is blinking somewhere else. The patch should make busybox vi
  behave more like original vi(m). Costs a few bytes but its worth it
  imho.
* new_text() is moved into init_text_buffer()
* the previously added update_ro_status() was moved info file_insert due
  to duplication removal mentioned above.
