core: fix Ubuntu code audit (cppcheck) results

See also http://review.gluster.org/#/c/7693/, BZ 1091677

AFAICT these are false positives:

[geo-replication/src/gsyncd.c:100]: (error) Memory leak: str
[geo-replication/src/gsyncd.c:403]: (error) Memory leak: argv
[xlators/nfs/server/src/nlm4.c:1201]: (error) Possible null pointer dereference: fde
[xlators/cluster/afr/src/afr-self-heal-common.c:138]: (error) Possible null pointer dereference: __ptr
[xlators/cluster/afr/src/afr-self-heal-common.c:140]: (error) Possible null pointer dereference: __ptr
[xlators/cluster/afr/src/afr-self-heal-common.c:331]: (error) Possible null pointer dereference: __ptr

Test program:

[extras/test/test-ffop.c:27]: (error) Buffer overrun possible for long command line arguments.
[tests/basic/fops-sanity.c:55]: (error) Buffer overrun possible for long command line arguments.

the remainder are fixed with this change-set:

[cli/src/cli-rpc-ops.c:8883]: (error) Possible null pointer dereference: local
[cli/src/cli-rpc-ops.c:8886]: (error) Possible null pointer dereference: local
[contrib/uuid/gen_uuid.c:369]: (warning) %ld in format string (no. 2) requires 'long *' but the argument type is 'unsigned long *'.

[xlators/mount/fuse/src/fuse-bridge.c:3080]: (error) Possible null pointer dereference: state
[xlators/nfs/server/src/nfs-common.c:89]: (error) Dangerous usage of 'volname' (strncpy doesn't always null-terminate it).
[xlators/performance/quick-read/src/quick-read.c:586]: (error) Possible null pointer dereference: iobuf

Rerunning cppcheck after fixing the above:

As before, test program:

[extras/test/test-ffop.c:27]: (error) Buffer overrun possible for long command line arguments.
[tests/basic/fops-sanity.c:55]: (error) Buffer overrun possible for long command line arguments.

As before, false positive:

[geo-replication/src/gsyncd.c:100]: (error) Memory leak: str
[geo-replication/src/gsyncd.c:403]: (error) Memory leak: argv
[xlators/nfs/server/src/nlm4.c:1201]: (error) Possible null pointer dereference: fde
[xlators/cluster/afr/src/afr-self-heal-common.c:138]: (error) Possible null pointer dereference: __ptr
[xlators/cluster/afr/src/afr-self-heal-common.c:140]: (error) Possible null pointer dereference: __ptr
[xlators/cluster/afr/src/afr-self-heal-common.c:331]: (error) Possible null pointer dereference: __ptr

False positive after fix:

[xlators/performance/quick-read/src/quick-read.c:584]: (error) Possible null pointer dereference: iobuf
