d9892fa0c3 i2c-tools: remove duplicate definitions

26ccd3d062 less: fix botched attempt to use last column
Commit 1ecb996 attempted to make read_lines() use the last column of
the terminal (as re_wrap() did).  There were two problems with this:

- The size of the buffer allocated for lines wasn't increased to allow
  for the extra character.

- The test for width overflow was moved after the point where the
  next character was added to the buffer.  This caused a buffer overflow
  in certain circumstances.

  For example, if the line beyond the end of the display was wider than
  the display read_lines() would initially read the partial line into a
  buffer.  When the user moved down read_lines() would be called again
  to ensure the rest of the line was read.  This would place the next
  character in the partial line before checking for overflow.

  This can be fixed by moving the test for overflow back to where it was
  before commit 1ecb996 and changing the comparison to `>` rather than
  `>=`.

There are two other places where buffers are created without allowing
for width+1 characters.

b27cf31003 less: further tweaks to regular file detection
Test explicitly for REOPEN flags:  update_num_lines is called
unconditionally so (num_lines != NOT_REGULAR_FILE) is also true when
num_lines contains a valid number of lines.

The call to fstat doesn't need to be in #if ENABLE_FEATURE_LESS_FLAGS:
the whole function is already in such a test.

1ecb996fd2 less: allow use of last column of terminal
When read_lines tests whether a character will fit on the current
line it checks the *next* character but in case of overflow doesn't
display the *current* one.  This results in the last column of the
terminal never being used.

The test in re_wrap (used when the terminal width changes or line
numbers are enabled/disabled) is different:  it does allow the use
of the final column.

d542d183e1 less: fix line number confusion
Much of the code refers to lines using indices into the flines
array (which splits lines into portions that fit on the terminal).
In some cases this is wrong and actual line numbers should be
used:

- when lines are being truncated rather than wrapped (-S flag)
- when line numbers have been entered by the user

Also fix a bug in numeric input and improve the display at EOF.

193ba408a4 less: improvements to verbose status messages
Make verbose status messages (-m/-M flags) behave more like the
real `less` command:

- fix display of line numbers so they're correct whether lines are
  being truncated (-S flag) or wrapped.
- don't display total lines or percentage when lines are read from
  stdin:  we don't have that information until we reach EOF.  When
  we do reach EOF the additional information is displayed.
- when lines are read from a file count the total number of lines
  so that we can display percentages.  Counting lines is avoided
  until the information is actually needed.  If the user pages to
  EOF the separate read pass can be avoided entirely.

Fixes Bug 7586

78cfa00154 less: correctly account for tabs when rewrapping lines
Lines are rewrapped when the terminal width changes or line numbers
are enabled/disabled.  The current calculation always adds eight to
the line length for a tab whereas it should only add enough to move
to the next tab stop.

This doesn't affect the display of lines, which is handled elsewhere
and gets tab stops right, but it does cause lines to be wrapped at
the wrong position.

7ca5c51cc8 i2c-tools: only try /dev/i2c/* if opening /dev/i2c-* fails with ENOENT
Trying to access /dev/i2c/* on every error after opening /dev/i2c-* can
mislead users who e.g. don't have root access. Instead of bailing-out
with "permission denied" we currently print "no such file or directory".

Fix it by trying open("/dev/i2c/%d") only if we got ENOENT.

Upstream i2cdetect tries to get any info it can from /sys and /proc even
when invoked by an unprivileged user, but we don't want to add unnecessary
bloat.

This makes "G" (goto end of input) command work as well as
/search_for_nonexistent_string: both will read to EOF now
even from somewhat slow input (such as kernel's "git log").

f17fbe1d36 nanddump: add options --bb=skipbad and padbad
In mtd-utils, the bad block options changed in favor of
--bb=[skipbad|padbad|dumpbad] and omitbad has been removed.

This patch add the --bb=skipbad and padbad methods to busybox' nanddump.
padbad is the current default behaviour.
The difference between skipbad and omitbad is this one:
On a 16K block NAND, if the 1st block of mtd0 is bad, we'll have:
nanddump  -b -l 16384 /dev/mtd0 | wc -c
0
nanddump  --bb=skipbad -l 16384 /dev/mtd0 | wc -c
16384 <- data from 1st good block

cbf3bfa57a nanddump: correct rounding to next page (lead to infinite loop)
The rounding to next page formula was wrong:
ex: (len | ~(meminfo->writesize - 1)) + 1;
len=128K
writesize=4K
(len | ~(meminfo->writesize - 1)) + 1 => 4 294 963 201 ?!

correct rounding formula:
((len - 1) | (meminfo->writesize - 1)) + 1 => 128K
len = 130K
((len - 1) | (meminfo->writesize - 1)) + 1 => 132K

modprobe nandsim parts="20,20" badblocks="22,23"

without patch:
nanddump  /dev/mtd1 | wc -c
[...] infinite loop

with the patch:
nanddump /dev/mtd1 | wc -c
