* Remove backport patch filemode-fix.patch.
* Update --with-kernel=${STAGING_DIR_HOST}/${prefix} to find kernel
  headers (linux/*.h) to fix the error:
| checking kernel supports perf_events... unknown -- perf_event.h not found
| ERROR: You requested to build oprofile with '--with-kernel=/buildarea/lyang1/test_f2/tmp/work-shared/qemux86/kernel-source',
| but headers were not accessible at the given location.
| Be sure you have run the following command from within your kernel source tree:
|      make headers_install INSTALL_HDR_PATH=<kernel-hdrs-install-dir>
| Then pass <kernel-hdrs-install-dir> to oprofile's '--with-kernel' configure option.
| configure: error: Unable to build oprofile. Exiting.

Seed the xsltproc detection with "not found" to avoid determinism races with the
documentation which doesn't build correctly with our xsltproc.

opcontrol is now dropped and replaced with the operf interface. As such, we drop
the opstart/opstop commands and any patches related to the old removed interfaces.

Some patches were also mered upstream so those are also dropped.

There is also a problem found on mips with the security flags enabled, the
patch has more specific details.

oprofile doesn't want GNU-levels of automake strictness so tell it to be
"foreign".

This commit detects the root home directory dynamically with changes to
the opcontrol script and the oprofile gui app source.

The commit replaces an earlier fix that detected and adjusted a
'non-standard' root home directory at build time.  The advantage of this
patch is that the oprofile tools are adjusted to the current run-time
path to ~root, not the build time path.

The commit changes the oe-core oprofile recipe by adding the PTEST
interface, implementing do_compile_ptest() and do_install_ptest().

The install routine adds several files that only the regression tests
require. Also, a patch is necessary to inhibit executing the tests on
the build host and to point to the correct target directory for the
libutil++ test 'file-manip-tests'.

That test requires the recipe to set SRCDIR in the build environment
instead of determining the value from build-time host paths as for a
self-hosted build.
