bitesize: work with different versions of awk and bash
...
This patch tries to fix following bitesize issues,
1. Error flooding messages when array index value is negative.
2. the smax in gawk was treated as string, that cause bug when
perf return zero IO count.

killsnoop: can't work with mawk
...
On Ubuntu Linux release, mawk is used by default. This issue caused
killsnoop can't work on Ubuntu by default.
There are two issues,
a. The strtonum is not supported by mawk.
Try to use int to convert string to number.
For gawk, int usage need the --non-decimal-data option.
On very old RHEL release(2.6.18 kernel), the gawk can support
this option.
b. killsnoop still has no results due to mawk buffering porblems.
Using -W interactive could solve this isue.
The option is available on mawk 1.2, RHEL 4+ should support it.

execsnoop: Instrument sys_execve first
...
On my kernel (3.16 amd64), stub_execve can't be instrumented, and
do_execve gets instrumented but fails silently (no events are caught).
Print which implementation is used.
Make sure do_execve is tried last due to silent failures.
