display_header() code to parse meminfo as is was buggy:
- uninitialized variables were used if meminfo was not as expected
- meminfo parsing failed on new kernels (3.14+) as new field 'MemAvailable'
was introduced between MemFree and Buffers
- shared memory was handled only for ancient kernels (2.4.x and earlier)
as result Buffers and shared memory fields were shown with bogus values
on current kernels.
The new code does not try to parse the old style summary header, as the
separated fields are always present (it saves code size). Additionally,
both Shmem (2.6+) and MemShared (2.4 and earlier) fields are now parsed
and summed for shared memory usage; as only one of them exists depending
on kernel version.
display_topmem_header() parses also meminfo so this makes it use the
same code for code shrink.

It is an interesting trick, but so far I only managed to make it work
correctly, not to make it faster and/or smaller.
The code is ifdefed out for now.

During link-local IP resolution, if a regular ARP request is received
during the ARP probe period, it will incorrectly cause a target IP
conflict. This then leads to a new IP being picked unnecessarily.
Per RFC 3927, section 2.2.1, we should flag a target IP conflict only if
the source IP is null, the target IP matches our IP, and the source
hw addr does not match our hw addr.

Like d3092c99, this change adds support for the DHCP "path-prefix"
option, as defined in RFC 5071. We use the string identifer
"pxepathprefix".
Adding this option makes string parsing in the hook scripts simpler.

display() function returns the length of the value we are displaying + 1.
As a consequence, if we have field=value\0field=value\0field=value in the
binary, then the second occurence will be skipped as ptr will miss the first
character of the following field.
Example trying to list aliases from ixgbe.ko on a 3.2 kernel.
- In the module we have:
alias=pci:v00008086d00001560sv*sd*bc*sc*i*\0
alias=pci:v00008086d0000154Asv*sd*bc*sc*i*\0
alias=pci:v00008086d00001557sv*sd*bc*sc*i*\0
alias=pci:v00008086d0000154Fsv*sd*bc*sc*i*\0
alias=pci:v00008086d0000154Dsv*sd*bc*sc*i*\0
...
- Using modinfo -F alias ixgbe returns:
alias: pci:v00008086d00001560sv*sd*bc*sc*i*
alias: pci:v00008086d00001557sv*sd*bc*sc*i*
alias: pci:v00008086d0000154Dsv*sd*bc*sc*i*
...
This problem appeared with kernel commit "modules: no need to align .modinfo
strings" b6472776816af1ed52848c93d26e3edb3b17adab in 2.6.37.
Fix this by not trusting display() return value but increment ptr by strlen(ptr)
(the same way as depmod.c does).

Move last_log_time from a single global to *each logFile_t*
so that we can actually apply the logic to every log-file
in multi-file configurations, rather than working only
for the first file written in each 1-second interval
and then leaving the others connected to possibly wrong files.

We don't have an INIT_FIRST, so let's rename INIT_LAST to INIT_FUNC
to imply that the function is called at program start-up.
Also: the priority argument for __attribute__((constructor)) isn't
used, so let's remove it.

busybox stat tries to always print the selinux context, even if it
is not requested which leads to a segmentation fault due to
dereferencing a null-pointer.
This also changes the format-string used to print the context to
so it actually produces useful output.

When we merely chdir to saved "real" root fd,
exec("proc/self/exe") works for static executables but not
for dynamic ones (they can't find their interpreter).
With this patch, we also *chroot* to real root.
As a bonus, this gives us proper usernames, timezone conversion
etc.

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

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

The find utility uses a hardcoded value of 32 * 1024 as the limit of
the command-line length when calling 'find -exec ... {} +'. This results
in over 4 times more execve() calls than in coreutils' find.
This patch uses the limit defined in system headers.
