This patch:
* Ensures that all calls to `jerry_port_log` in jerry-core happen
via macros defined in jrt.h. Also, it unifies the names of those
macros: as `JERRY_ERROR_MSG` and `JERRY_WARNING_MSG` gave a good
pattern that was well aligned with the naming scheme of the log
level enum, `JERRY_DLOG` and `JERRY_DDLOG` were rewritten to
`JERRY_DEBUG_MSG` and `JERRY_TRACE_MSG`.
* Ensures that all debug logging code parts of jerry-core (i.e.,
memory statistics, JS byte-code dumps, and RegExp byte-code
dumps) are guarded by macros: `JMEM_STATS`,
`PARSER_DUMP_BYTE_CODE`, and `REGEXP_DUMP_BYTE_CODE`, which in
turn are controled by cmake build system feature flags
`FEATURE_MEM_STATS`, `FEATURE_PARSER_DUMP`, and
`FEATURE_REGEXP_DUMP`.
* Ensures that all debug logging functionalities can be controled
during run time (provided that they were enabled during build
time): the engine has `JERRY_INIT_MEM_STATS[_SEPARATE]`,
`JERRY_INIT_SHOW_OPCODES`, `JERRY_INIT_SHOW_REGEXP_OPCODES` init
flags, and the default unix/linux command line app has
corresponding command line switches.`
* Drops `FEATURE_LOG`, `JERRY_ENABLE_LOG`, and
`JERRY_INIT_ENABLE_LOG`, as their name was misleadingly general,
even though they mostly controled the regexp engine only. The
above-mentioned `*REGEXP*` things mostly act as their
replacements.
* Updates build, test, and measurement tool scripts, and
documentation.

The "length" property name is the most frequently used built-in string
and also frequently created by various hot-paths. New functions are
added to improve the speed of the "length" string creation.

Short summary of the changes:
- The ecma_reference_t is removed, and its helper functions are deleted.
- The delete operation does not depend on ecma_reference_t anymore.
- A new resolve function is added which returns the current value
of a named binding in the context chain.
- The vm_op_set_value does not perform type conversions when its arguments
has the appropriate types.

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.

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.

the three boolean arguments of ecma_create_named_data_property and the
two boolean arguments of ecma_create_named_accessor_property are combined

four arguments, since these arguments can be passed in registers.

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`.
