udhcpd: add option for tweaking arpping
Some clients have a very short timeout for sending the DHCP
DISCOVER, shorter than the arpping timeout of 2000 milliseconds
that udhcpd uses by default.
This patch allows tweaking the timeout, or disabling of arpping
altogether, at the risk of handing out addresses which are
already in use.

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.

modinfo: fix module parsing with kernel >= 2.6.37
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: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*

strings"

Fix this by not trusting display() return value but increment ptr by strlen(ptr)

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
