* 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

Endianness was not properly set/detected for AArch64. Once that is
fixed, the platform is well-supported.

Re-styling of the sources revealed that the false branch of an
if-else construct in `asin` did not contain all the statements
that it should. (This was an issue -- a bad smell at least --
that's been around since 1995, according to the legacy SCCS ID.)

* First re-style was done automatically by indent to minimize the
chance of errors during rewrite.
* Manual changes were applied to non-critical places only (comments
and spaces):
* Replaced all tabs with spaces.
* Fixed tab stops in formulae in function comments.
(Note: ASCII art for math formulae (especially for super- and
subscripts) is a terrible idea.)
* Unified the style of function comments.
* Moved some in-code comments to their right places, which indent
couldn't handle.
* Added spaces to formulae of in-code comments to make them more
readable.
* Added braces mandated by jerry style guidelines.
* Added parentheses to multiline #ifdef.

* Made helper functions static.
* Changed the signature of __kernel_rem_pio2 not to require the
ipio2 argument

Keep IEEE code paths only:
* removed SVID, XOPEN, POSIX code paths from everywhere.
* deleted s_lib_version.c, as version is only useful if multiple
standards are supported.
* deleted k_standard.c, as it handles non-IEEE exception cases only.
* renamed the e_{acos,asin,atan2,exp,fmod,log,pow,sqrt}.c sources as
s_.*, dropped the __ieee754_ prefix from the names of the
appropriate functions therein, and deleted the
w_{acos,asin,atan2,exp,fmod,log,pow,sqrt}.c wrapper code.
Keep C99 declaration variants only:
* removed old C-style function declaration variants.
* removed data declaration variants where const qualifier was not
used.
Clean unused sources/functions:
* removed s_{rint,significand,tanh}.c and the appropriate functions
defined therein.

Most of the legacy version control IDs in fdlibm are already simple
comments at the beginning of the source files. However, in some
files, there are leftover global variables and pragmas. (The global
variable in e_pow.c even increases the .data section in both debug
and release builds.) This patch turns all legacy IDs to comments of
unified style.

Jerry-libc and jerry-core already uses the block-based approach.
Now, removing the last remnant of the macro approach from fdlibm as
well.

When using the -std=c99 the gcc does not defines the i386 macro
just the __i386 and __ i386 __.
