[Dle-develop] system call trace test program

[Satoru M. <sat...@hd...>]

This is a set of programs for testing systemcall tracepoints. It includes
test programs which call x86_64 and ia32 system calls. We can test all
system call entry path which described below.

 1. syscall (arch/x86_64/kernel/entry.S)
 2. ia32_sysenter_target (arch/x86_64/ia32/ia32entry.S)
 3. ia32_syscall (arch/x86_64/ia32/ia32entry.S)
 4. ia32_cstar_target (arxh/x86_64/ia32/ia32entry.S)

Also it includes the kernel module which adds probe functions to
tracepoint and system call entry points with kprobes. This module
traces the process which specified with pid module parameter.

As a result, We can test system call tracing function for all entry
paths with this test programs.
