* 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

#### Apply patch to ESP8266 SDK
|
|
|
|
As `iram` is quite small to fit all the codes but linker tries to put it there.
|
|
To force JerryScript codes to be placed at the `irom` section,
|
|
need to change the order and tell the linker as below;
|
|
|
|
```

Second file is to modify `irom` size so that it can hold all the codes and data.
|
|
This can be done by giving another `SPI_SIZE_MAP`.
|
|
For now, I'll use this manual modification.

#### Need to get setjmp / longjmp
|
|
|
|
Extract and copy from the SDK.
|
|
|
|
```
|
|
cd ~/harmony/jerryscript/targets/esp8266/libs
|
|
ar -xv $SDK_PATH/lib/libcirom.a lib_a-setjmp.o
|
|
```
