The new literal storage keeps ecma strings rather than having a
custom string implementation which duplicates the string management
routines. Conversions between string implementations are eliminated
which improved the performance by 4%.

Several internal properties are removed and directly stored as
part of the object. Faster built-in and JS function processing.

* 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.

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 three boolean arguments of ecma_create_named_data_property and the
two boolean arguments of ecma_create_named_accessor_property are combined
into one uint8_t argument. On ARM-32 it is preferred to have less than
four arguments, since these arguments can be passed in registers.

The 'mem_' prefix is too general, so it might clash with
symbols in other libraries. Renamed the directory, file,
funtion and type names.

Those internal properties which have a primitive value field or where the property value type
is an ecma_object_t ptr were checked earlier.

The internals have surprisingly large number of unused functions at
surprising places. This patch cleans them out to make maintenance
easier and to prevent dead code having effect on future decisions.
The patch intentionally does not try to clean up public API but
focuses on internal modules only that are/should not be reachable
from "outside".
However, unit tests do access private API, thus tests of literal
storage had to be adjusted.

itself seems a step back, but the primary aim is opening future
optimization opportunities. The list of changes follows:
- Property is changed to be an abstract type, which has type, flags,
and a value. It does not have a name anymore and property pointers
cannot be compressed.
- Full (32 bit) ecma values can be property values. This allows
using non-compressed pointers for ecma values in the future.
- The property chain is not restricted to the same item anymore,
it can contain hash maps, arrays in the future.

Fixed doc comments issues:
* Fixed mistyped param doc comments (`/**<` is OK, `/** <` is not).
* Put special characters (e.g., pipe, backslash, etc.) in quotes, as they can
confuse doxygen and it will print lots of various warnings. For the sake of
completeness and consistent style, also quote some special characters in
re-bytecode.h
* Added missing `@{`s, removed extra `@}`s.
* Turned `/*` comments to `/**<` doc comments.
Ensured same style for doc groups everywhere:
* Where `\addtogroup`, `@{`, and `@}` doxygen commands are used, the order to be
followed is: license, `#ifndef` guards (in headers), includes, `\addtogroup`
and `@{`, main code content, `@}`, `#endif` guards (in headers).
* Multiple `\addtogroup`s or multiple `@}`s should be in the same doc comment.
* First `\addtogroup` should be on the very first line of a doc comment, i.e.,
`/** \addtogroup`.

There have been several renamings of header files but the
ifndef/define/endif preprocessor directives did not always follow
the file name changes (or perhaps never followed a unified naming
scheme). This patch gets all headers aligned with the style of the
majority.

E.g.,
* `ssize_t` was used where `lit_utf8_size_t` or `jerry_api_size_t`
would have been correct,
* `lit_utf8_size_t` was used where `ecma_length_t` would have been
correct.
Note, the patch also includes internal and public API changes:
* `ecma_string_to_utf8_string` does not return negative value if
output buffer is not large enough to contain the string; the
buffer is expected to be large enough. (`ecma_string_get_size`
can be used to retrieve the required size.)
* `jerry_api_string_to_char_buffer` adapts the same logic (and
`jerry_api_get_string_size` can be used to determine the
required size of the buffer).
