The pre-scanner now is able to track all variable declarations and produces a compressed
stream which store this data for each function and catch block. When a function or
catch block is parsed, this information is decoded and the appropriate variables are
created. Furthermore a stack scope is created which contains the currently available
local variables and their register or literal index.

There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.
Main changes:
* The following macros are now 0/1 switches:
** Renamed CONFIG_ECMA_LCACHE_DISABLE to JERRY_LCACHE.
** Renamed CONFIG_ECMA_PROPERTY_HASHMAP_DISABLE to JERRY_PROPERTY_HASHMAP.
** Renamed CONFIG_DISABLE_UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
** Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
** Renamed JERRY_DISABLE_JS_PARSER to JERRY_PARSER.
** Renamed JERRY_ENABLE_ERROR_MESSAGES to JERRY_ERROR_MESSAGES.
** Renamed JERRY_ENABLE_EXTERNAL_CONTEXT to JERRY_EXTERNAL_CONTEXT.
** Renamed JERRY_ENABLE_LINE_INFO to JERRY_LINE_INFO.
** Renamed JERRY_ENABLE_LOGGING to JERRY_LOGGING.
** Renamed JERRY_ENABLE_SNAPSHOT_EXEC to JERRY_SNAPSHOT_EXEC.
** Renamed JERRY_ENABLE_SNAPSHOT_SAVE to JERRY_SNAPSHOT_SAVE.
** Renamed JERRY_SYSTEM_ALLOCATOR to JERRY_SYSTEM_ALLOCATOR.
** Renamed JERRY_VM_EXEC_STOP to JERRY_VM_EXEC_STOP.
** Renamed JMEM_GC_BEFORE_EACH_ALLOC to JERRY_MEM_GC_BEFORE_EACH_ALLOC.
** Renamed JMEM_STATS to JERRY_MEM_STATS.
** Renamed PARSER_DUMP_BYTE_CODE to JERRY_PARSER_DUMP_BYTE_CODE.
** Renamed REGEXP_DUMP_BYTE_CODE to JERRY_REGEXP_DUMP_BYTE_CODE.
* Recursion check changes:
** Renamed REGEXP_RECURSION_LIMIT to JERRY_REGEXP_RECURSION_LIMIT.
** Renamed VM_RECURSION_LIMIT to JERRY_VM_RECURSION_LIMIT.
* Attribute macro changes:
** Renamed JERRY_CONST_DATA to JERRY_ATTR_CONST_DATA.
** Renamed JERRY_HEAP_SECTION_ATTR to JERRY_ATTR_GLOBAL_HEAP.
Now the macro can specify any attribute for the global heap object.
* Other macro changes:
** Renamed CONFIG_MEM_HEAP_AREA_SIZE to JERRY_GLOBAL_HEAP_SIZE.
Then new macro now specify the global heap size in kilobytes.
* Updated documentations to reflect the new macro names.

Direct strings are a new type of direct ecma-values (no memory allocation
is needed for encoding them) in JerryScript. Currently magic strings,
external magic strings and uint values are encoded as direct strings.
The constant pool of JerryScript byte-code is changed to hold ecma-values
rather than cpointers to support direct strings.

* Replace JERRY_JS_PARSER feature guard with JERRY_DISABLE_JS_PARSER
All feature guards of jerry-core are deciding about the inclusion
or exclusion of a feature based on the state (defined or undefined)
of a macro -- except for the JS parser guard, which requires
`JERRY_JS_PARSER` to be defined with a value of either 0 or 1. This
has some issues:
- The engine cannot be built with a "clean" compiler invocation,
i.e., without any `-D` command line macro definitions. This is
painful for targets that must use a different build system from
the project's own python/cmake-based one.
- Some build systems in targets and even some code in jerry-code
are already confused about the different semantics of
`JERRY_JS_PARSER`, and simply define it without a value and make
decisions based on the macro being simply defined or not.
This patch renames the guard to `JERRY_DISABLE_JS_PARSER` and makes
use of it in jerry-core based on its state, not based on its value.
As obvious from the guard name, the default for the JS parser is
that it is included in the build.
The patch also touches those targets in the repository that
explicitly defined the original macro (correctly or incorrectly).
* Make cppcheck verbose
Cppcheck can be quite slow sometimes, especially on Travis CI,
which has a "10 mins without output means failure" rule. As the
code base of the project grows, we start to undeterministically
fall over that limit. Thus, this PR makes cppcheck verbose to
ensure that it keeps Travis CI continuously fed with output.

Renamed FEATURE_PARSER_DISABLE to FEATURE_JS_PARSER.
Fixed the build error that occurred in case of disabled js-parser.

Remove the parser so we can save space if we are
only interested in running snapshots.
Removing the parser enables the snapshot execution.

Since the project is now hosted at the JS Foundation we can move to unified copyright notices for the project.
Starting with this commit all future contributions to the project should only carry the following copyright notice (except for third-party code which requires copyright information to be preserved):
"Copyright JS Foundation and other contributors, http://js.foundation" (without the quotes)
This avoids cluttering the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly. Also dropping the year from the copyright notices helps to avoid yearly code changes just to update the copyright notices.
Note that each contributor still retains full copyright ownership of his/her contributions and the respective authorship is tracked very accurately via Git.

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 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%.

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

memory consumption, because the new allocator uses less memory if
the size as available when a block is freed. Snapshot generation
is also simplified.
