Commit ac6495f6f (vi: allow ctrl-D to reduce indentation) treated
ctrl-D during autoindent as a backspace. This was adequate for
indentation using tabs but doesn't work well with the expandtab
option. In the latter case it's necessary to backspace over all
the spaces.
Make ctrl-D work correctly when spaces are present in the indent.
Also, make it behave more like vim:
- ctrl-D is independent of autoindent;
- indentation is reduced even when the cursor isn't positioned at
the end of the indent.

This implements the vim option expandtab in BusyBox vi. From
vim help:
In Insert mode: Use the appropriate number of spaces to insert a
<Tab>. Spaces are used in indents with the '>' and '<' commands and
when 'autoindent' is on. To insert a real tab when 'expandtab' is
on, use CTRL-V<Tab>.
This implementation doesn't change how BusyBox vi handles autoindent:
it continues to copy the indentation from a neighbouring line. If
that line has tabs in its indentation so too will the new line.

Line addresses in colon commands can be defined using an expression
that includes '+' or '-' operators. The implementation follows
traditional vi:
- The first term in the expression defines an address. It can be
an absolute line number, '.', '$', a search or a marker.
- The second and subsequent terms must be non-negative integers.
- If the first term is missing '.' is assumed. If the operator is
missing addition is assumed. If the final term in missing an
offset of 1 is assumed.
Thus the following are valid addresses:
.+1 .+ + .1
.-1 .- -
The following are not valid (though they are in vim):
.+$ .$ 2+.

BusyBox vi didn't have proper handling for invalid markers or
unsuccessful searches in colon line addresses. This could result
in the wrong lines being affected by a change.
Detect when an invalid address is specified, propagate an error
indicator up the call chain and issue a warning.

When whitespace has been automatically added to a new line due to
autoindent entering ctrl-D should reduce the level of indentation.
Implement an approximation of this by treating ctrl-D as backspace.
For the common case of indentation using tabs this is good enough.
My attempt at a full implementation was three times bigger.

Vi places the cursor on the last column of a tab character whereas
BusyBox vi puts it on the first. This is disconcerting for
experienced vi users and makes it impossible to distinguish
visually between an empty line and one containing just a tab.
It wasn't always this way. Prior to commit e3cbfb91d (vi: introduce
FEATURE_VI_8BIT) BusyBox vi also put the cursor on the last column.
However there were problems with cursor positioning when text was
inserted before a tab. Commit eaabf0675 (vi: multiple fixes by
Natanael Copa) includes a partial attempt to fix this. (The code is
still present but it's never executed. Clever compilers optimise it
away.)
Revert the changes of commit e3cbfb91d and fix the insert problem
for all tabs, not just the first.
To quote Natanael: "Costs a few bytes but its worth it imho".

The undo queue didn't record deleted characters properly. For
example, insert some text, backspace over a couple of characters
then exit insert mode. At this point undo will restore two nulls
instead of the deleted characters.
The fix is in undo_push(): record the state of the UNDO_USE_SPOS
flag and clear it before using 'u_type'.
Also, update the comments to reflect the fact that UNDO_QUEUED_FLAG
isn't actually used.

Commit 4bdc914ff (build system: fix compiler warnings) added a
test on the return value of fgets() in split-include.c.
During bisection it's possible to go back to a state where a
configuration value didn't exist. This results in an empty
include file corresponding to the missing feature. If a
subsequent bisection returns to a state where the feature exists
split-include treats the empty file as an error and the build
fails.
Add a call to ferror() to distinguish between fgets() failing
due to an error and due to there being no data to read.

The behaviour introduced by commit 31c765081dc4 ("watchdog: stop
watchdog first on startup") causes warnings in the kernel log when the
nowayout feature is enabled:
[ 16.212184] watchdog: watchdog0: nowayout prevents watchdog being stopped!
[ 16.212196] watchdog: watchdog0: watchdog did not stop!
The latter may also appear by itself in case the watchdog is of the
type that cannot be stopped once started (e.g. the common
always-running gpio_wdt kind).
These warnings can be somewhat ominous and distracting, so allow
configuring whether to use this open-write-close-open sequence rather
than just open. Also saves a bit of .text when disabled:

Make it default n:
- It's a workaround for one specific type of watchdog (and
that seems to be a defect in the kernel driver)
- Even when not enabled in busybox config, it can easily be
implemented outside busybox
- Code size
- Commit 31c765081dc4 should be considered a regression for all the
boards that now end up with KERN_CRIT warnings in dmesg.
- The author of that commit said "This use case is evidently rare, so
if it is indeed causing problems for other people I'd OK then I
understand whatever needs to be done." in the v1 thread.
