perf probe: Provide perf interface for uprobes
- Enhances perf to probe user space executables and libraries.
- Enhances -F/--funcs option of "perf probe" to list possible probe points in
an executable file or library.
- Documents userspace probing support in perf.
[ Probing a function in the executable using function name ]
perf probe -x /bin/zsh zfree
[ Probing a library function using function name ]
perf probe -x /lib64/libc.so.6 malloc
[ list probe-able functions in an executable ]
perf probe -F -x /bin/zsh
[ list probe-able functions in an library]
perf probe -F -x /lib/libc.so.6
