The Math.pow implementation relies on libm's pow. However, the ISO C
and ES5.1 standards differ on pow:
* `x ** NAN` is NAN in ES but `+1 ** y` is 1 in C
* `+-1 ** +-INF` is NAN in ES but 1 in C
This patch:
* Modifies the Math.pow implementation to handle the special cases
instead calling pow.
* Adds a test case to jerry-test-suite as it did not test
`Math.pow(1,NaN)`.
* Fixes jerry-libm's pow, as it was not standard conforming, which
helped hiding the error in Math.pow.
* Updates the unit test for libm.

We removed that implementation where the build directory isn't set up to build with exactly one
configuration of the project but potentially several variants: the same build directory
can/must be used for debug and release builds, for full or compact profile versions, etc.
So we reworked the CMakeLists, and now one build dir deal with exactly one configuration
of the project's libraries and tools.

Added errol implementation. Fixed '3d-raytrace.js', because
the new algorithm has better precision and also reduce the
code size.

* 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.

* 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
