The most informative message can be generated at the location
where error is detected. The "error codes" are stupid:
print error meesage immediately, then just return "there was an error"
indicator.
All error codes will be converted. For now, converting these two.
For now, this and following changes will degrade error messages

Installing headers from upstream i2c-tools makes it impossible to
build the busybox version due to redefined symbols. This is caused by
the fact that linux/i2c-dev.h from i2c-tools overwrites the one from
linux uapi and defines symbols already defined by linux' linux/i2c.h.
Drop this include and simply re-implement the relevant defines from
linux/i2c-dev.h in miscutils/i2c-tools.c.

FEATURE_GETOPT_LONG made dependent on LONG_OPTS.
The folloving options are removed, now LONG_OPTS enables long options
for affected applets:
FEATURE_ENV_LONG_OPTIONS FEATURE_EXPAND_LONG_OPTIONS
FEATURE_UNEXPAND_LONG_OPTIONS FEATURE_MKDIR_LONG_OPTIONS
FEATURE_MV_LONG_OPTIONS FEATURE_RMDIR_LONG_OPTIONS
FEATURE_ADDGROUP_LONG_OPTIONS FEATURE_ADDUSER_LONG_OPTIONS
FEATURE_HWCLOCK_LONG_OPTIONS FEATURE_NSENTER_LONG_OPTS
FEATURE_CHCON_LONG_OPTIONS FEATURE_RUNCON_LONG_OPTIONS
They either had a small number of long options, or their long options are
essential.
Example: upstream addgroup and adduser have ONLY longopts,
we should probably go further and get rid
of non-standard short options.
To this end, make addgroup and adduser "select LONG_OPTS".
We had this breakage caused by us even in our own package!
#if ENABLE_LONG_OPTS || !ENABLE_ADDGROUP
/* We try to use --gid, not -g, because "standard" addgroup
* has no short option -g, it has only long --gid.
*/
argv[1] = (char*)"--gid";
#else
/* Breaks if system in fact does NOT use busybox addgroup */
argv[1] = (char*)"-g";
#endif
xargs: its lone longopt no longer depends on DESKTOP, only on LONG_OPTS.
hwclock TODO: get rid of incompatible -t, -l aliases to --systz, --localtime
Shorten help texts by omitting long option when short opt alternative exists.
Reduction of size comes from the fact that store of an immediate
(an address of longopts) to a fixed address (global variable)
is a longer insn than pushing that immediate or passing it in a register.
This effect is CPU-agnostic.

Some watchdog implementations may do things other than issue
a reboot on a watchdog timeout. In this case, there's the
possibility of restarting this program from the state of
the watchdog device not being properly stopped (done by writing
a 'V' and closing the device). Since it wasn't stopped, the
driver may not be able to restart the watchdog when this program
reopens it and starts pinging it.
To fix this, the code will always first issue the stop when it
starts up.

Since the fact that we're using common_bufsiz1 here isn't obvious (no

The non-fancy version of the from_cpuset uses CPU_SETSIZE as if it
represents the number of bytes in the cpuset, while it is actually
the number of bits. This leads to out-of-bounds accesses on the
cpu_set_t in the big-endian case. Basically all uses of CPU_SETSIZE
have to be divided by 8. This is done correctly in the fancy version
of from_cpuset.
In addition, the big-endian case is completely wrong to begin with.
All standard C libraries that I know of implement cpu_set_t as an
unsigned long array, so both for big and little endian, the least
significant bits are in the beginning of the array. Therefore, the
approach taken for the little endian case is equally valid. We only
need special handling for big endian when CPU_SETSIZE is large and
we use an unsigned long long to get more bits out.

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.

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.

Add a function to package the test that detects whether enough has
been read from the file to allow a screenful to be displayed.
Also use this to determine when to display '(END)' in the status
line. The previous code was incomplete and didn't handle truncated
lines (-S flag) properly.

Move the code to detect non-regular files to the point where the
file is being opened. If num_lines == READING_FILE guarantees
that the file is regular.
Detect when a file becomes unreadable between it first being opened
and the call to update_num_lines. Mark the file as being non-regular

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.

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.

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 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

We set a default path for the directory where pidfiles are create
when FEATURE_PIDFILE is selected. The default has no effect on
applets which must specify a pidfile path on the command line to
run, and it can be overridden by applets which optionally allow
the user to specify the pidfile path.
We also add pidfile write/remove support for klogd, ntpd and watchdog.
For syslogd, we add a missing remove_pidfile() for better cleanup
on daemon exit.
