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%.

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.

or no arguments at all. To improve the performance, the branch argument
flag is changed into a get argument type which eliminates a flag check
for all executed opcodes. Furthermore branch opcodes skip the put result
phase by changing the "break" to "continue" statements.

- Branch argument information is encoded in the vm byte
code data, so CBC flags are not loaded anymore
- The free_flags variable is removed from the vm_loop
- Two cases are removed from "get arguments", argument
processing is simplified
- The two opcode tables are merged to one
- The VM_OC_POP opcode has no result, so the break is changed to continue.
- The VM_OC_PUSH_NUMBER can use ecma_make_integer_value.

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

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`.

Currently, if a regexp contains a character class and that
character class contains a hex-specified code point -- either
\uNNNN or \xNN --, then the character 'u' or 'x' is added to the
character class as well. This patch fixes the error and also adds
a regression test covering the issue.

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).

* Fix "end of file while inside a group" doxygen warnings.
* Fix "unknown command" doxygen warnings caused by incorrect
argument references. Instead of `@foo`, `@a foo` is the proper
format.
* Fix "unknown command" doxygen warnings caused by incorrect
parameter direction specifications. Instead of `@in`, `@out`,
and `@in-out`, `[in]`, `[out]`, and `[in,out]` are the proper
formats.
* Wrapping special characters in quotes to avoid doxygen
confusion. Raw pipe, semicolon, dot, backslash, etc. characters
can drive doxygen into various misinterpretations and warnings.
E.g.:
```
End of list marker found without any preceding list items
Found unknown command
```
Putting quotes around such text snipets eliminates the errors.
* Fix the documentation of `ecma_builtin_global_object_print`. Raw
<> and \ sequences confused doxygen in various ways (it tried to
interpret them as XML tags and doxygen commands).
* Fix "ignoring title that does not match old title" doxygen
warnings. At some places, the group titles were out of sync, at
others, the group names were incorrect.
* Fix "parameters are not documented" doxygen warnings. Fixing
various typos in the inline parameter documentations (`/*`,
`/**`, `/** <`, and `/**>` are all considered incorrect, the
right format is `/**<`).
