oprofile: Introduce new oprofile sample add function (oprofile_add_ext_hw_sample)
This patch introduces a new oprofile sample add function
(oprofile_add_ext_hw_sample) that can also take task_struct as an
argument, which is used by the hwsampler kernel module when copying
hardware samples to OProfile buffers.
Applied with following changes:
* removed #include <linux/module.h>
* whitespace changes
* removed conditional compilation (CONFIG_HAVE_HWSAMPLER)
* modified order of functions
* fix missing function definition in header file
