0511091e8a Streamline copyright notices across the codebase. (#1473)
Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.

Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):

"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)

This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.

Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

3ba286f3e1 Turn modified fdlibm into Jerry's own libm
* Rename modified fdlibm to jerry-libm
  * Move third-party/fdlibm to jerry-libm
  * Rename original fdlibm.h to jerry-libm-internal.h
    * And remove it from the public headers.
  * Rename jerry-libm's public header to math.h
    * This also makes jerry-core sources include `<math.h>`. Therefore,
      should anyone want to use a different libm implementation with
      jerry, it becomes possible. (The same way as we provide a minimal
      libc with standard headers, but should it be insufficient or
      conflicting for someone, it can be replaced.)
  * Drop `s_` prefix from jerry-libm sources
    * The original fdlibm implementation had various prefixes (e.g., `k_`
      for sources of kernel routines, and `w_` for wrapper routines), but
      after the specialization of fdlibm to jerry, only `s_` remained.
      Since it does not encode anything anymore, it can be dropped.
  * Stylistic edits to jerry-libm's CMakeLists
    * Align project name with other CMakeLists in the code base
  * Move Jerry-LibM under Apache License
    * Using the same approach as was used by linux-wireless when ath5k
      driver license needed clarification. Solution was proposed by SFLC.
      External mail for future reference: http://lwn.net/Articles/247806/

* Tests & checks
  * Remove FD from the name of libm unit test-related files
  * Make vera++ and cppcheck check jerry-libm

* Targets
  * Speculative update of targets to use jerry-libm

91b1547fa5 Add unit testing of fdlibm
The project is relying on a variant of fdlibm, which has aleady
been edited but never verified for correctness. This patch adds
unit testing of fdlibm by:

* introducing a test generator that uses a trusted libm
  implementation to calculate correct and expected results of math
  functions
  (tools/gen-test-fdlibm.sh and tools/unit-tests/gen-test-fdlibm.c),
* adding tests created with the generator that stress all publicly
  exported functions of jerry's fdlibm
  (tests/unit/test-fdlibm.inc.h), and
* adding a unit test file to drive the generated tests
  (tests/unit/test-fdlibm.c).

Note: The test generator is not expected to be executed often, thus
it is not wired into the build system. If it gets edited, it must
be used locally to re-generate the .inc.h file.

During development, it turned out that tests/unit/test-common.h
included the system header math.h, which was only a bad smell until
now but became a real header conflict issue with the introduction
of the fdlibm unit test. Thus, this patch also changes the include
to fdlibm-math.h.
