top: fix and merge code to parse /proc/meminfo
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.

zcip: fix link-local IP conflict detection
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.

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: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).

swapon/swapoff: size reduction, cleanup, fixes, improvements
1) real swapon/swapoff handles also devices on the commandline with -a;
2) xstat(device) in swap_enable_disable aborts on error when cycling through
fstab so some devices are not handled;
3) duplicated code for ENABLE_FEATURE_SWAPON_DISCARD and
ENABLE_FEATURE_SWAPON_PRI was moved to functions.
4) silence some error messages with -a;
5) minor cleanups and code refactoring reduced the size as per bloat-check:
6) I also added support for /proc/swaps handling to swapoff:
"When the -a flag is given, swapping is disabled on all known swap devices
and files (as found in /proc/swaps or /etc/fstab)."
So now swapoff first cycles through /proc/swaps and then through fstab
to swapoff all devices.
