The build fails with enabled ALL_ON_ONE and enabled COMPILER_DEFAULT_LIBC options,
because the _BSD_SOURCE doesn't defined before including the sys/time.h.
In case of glibc, the 'timezone' is not part of C99 but part of POSIX, so we need
to define the _BSD_SOURCE feature test macro before including sys/time.h to get
the prototype for this struct.

There is no need for putting `LIT_CHAR_*` constants in const
scalars or arrays, they can be used directly. (There is especially
no need for arrays of 10 elements if only 2 of them are used.)

* Make constants static in `ecma_number_to_utf8_string`.
* Make `ecma_number_to_utf8_string` use early returns, and rewrite
its self-recursion in case of negative numbers.
* Make the stringification of decimal exponent in
`ecma_number_to_utf8_string` use `ecma_uint32_to_utf8_string`.
* Changed ERROL0 dtoa implementation to use the `double` type
instead of `ecma_number_t`. Thus, even is `ecma_number_t` is 32
bit wide, the algorithm works the same.
* Changed `ecma_number_to_decimal` to use the ERROL0 dtoa algorithm
for 32-bit floats as well.
* Changed `ecma_number_to_decimal` to generate the decimal string
representation of the mantissa instead of an `uint64_t` number.
* Changed `ecma_number_to_utf8_string` to make use of the already
available string representation of the mantissa, generated now by
`ecma_number_to_decimal`.
* Changed `ecma_number_to_utf8_string` not to use static arrays and
variables for digit, "e", etc. generation.
* Changed all `Number.prototype.toXXX` implementations and the
`ecma_builtin_number_prototype_helper_round` helper to make use
of the already available string representation of the mantissa,
generated now by `ecma_number_to_decimal`.
* Factored out the common stringification parts of all
`Number.prototype.toXXX` implementations into a new helper
`ecma_builtin_number_prototype_helper_to_string`.

Changed 'ecma_copy_or_ref_ecma_string' to 'ecma_ref_ecma_string'. It does
not copy the string if the maximum number of reference counter is reached,
but bails out with an error like the 'ecma_ref_object' function does.

When `val` is DBL_MAX, we get +inf from `ECMA_NEXT_FLOAT (val)`.
It is necessary to handle this case specially.

Parts:
* Rename ecma_string_to_utf8_string() to ecma_string_copy_to_utf8_buffer.
* Introduce ecma_string_to_utf8_bytes(), which wraps the usual 'function call-assertion' pair,
and check strict equality of size of the string and the buffer.

The cache stores only real properties now, because storing NULLs has
little benefit according to tests. Since only real properties are
stored now, there is no need to create real references to objects
and property names, which reduces the keeping of dead objects after
garbage collection.
