All members of an object must be valid when the garbage collector runs,
so no allocations are allowed during typed array initialization.
Fix issue #1605

Jerryscript. The changes include:
CMakeLists.txt: we added conditionals around GCC-specific flags, added
support for TI flags, and removed the always-on debugging flag (-g)
/toolchain_mcu_tim4f.cmake: new toolchain file uses TI-specific parameters
jerry-api.h: the sys/types.h file was #include'd but never used, so we
removed it
jrt-types.h: ditto
jerry-port-default-date.c: the TI toolchain doesn't include
sys/time.h, so we guarded uses of the package
ecma-objects-general.c: added initialization that Travis (the
auto-checking tool) required

The regression-test-issue-736.js is also changed, since it expects
throwing an error, which does not happen anymore because the "x"
variable is undefined.

It's generally considered a bad programming practice to have function declarations without parameter names.
This is another legacy from the early days of the project. Fix in one go to minimize history disruption.
Used a custom clang-tidy check to create the bulk of the change.

Extern keywords on function declarations/definitions provide no additional value since function declarations/definitions default to external linkage in C99, e.g. removing them won't change the semantics of the program.
The extern keywords were essentially a legacy from the early days of the project. This commit cleans this up across the whole codebase in one go to minimize history disruption.
The bulk of the changes in this commit were produced by a custom clang-tidy checker.
Note that variables declarations carrying the extern keyword are untouched by this commit since there the presence of the keyword actually has an impact on the semantics of the program.

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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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.

Property names were always required a string reference which consumed
a large amount of memory for arrays. This patch reduces this consumption
by directly storing the value part of certain strings.

This change allows easier access to array length which improves
the performance of inserting new items into an array and there
is no need to allocate length strings anymore. The trade-of is
that array length cannot be cached anymore.

Free a new bit in the property descriptor by combining internal
and special property types into one group. Also simplify checking
special properties since bit-and operation is not needed anymore.

This patch reduces memory consumption for strings such as "0" or "123"
by 8 bytes and "4294967295" by 16 bytes. The hash computation is changed
for using the lower 16 bits for these strings which is much faster than
converting the value to string first and compute the hash. The trade-of
is a small overhead when strings are created or concatenated.

The new code does not use value collections which reduces the argument array size by half.
JerryScript-DCO-1.0-Signed-off-by: Zoltan Herczeg zherczeg.u-szeged@partner.samsung.com
Instead of allocating a helper object, argument names are appended right
after the arguments objects. This reduces memory consumption and improve
performance as well. In the future this could be further improved by a
bitfield, but that would require a reference to the byte code which
might increase memory consumption in a few corner cases.

Class and value internal properties are always exists for primitive
types (e.g. Boolean, Regex) so they can be stored right after the
object. This improve property access (since internal properties are
searched by a slow linear algorithm) and reduces memory consumption,
since only 8 byte is allocated for these two properties instead of
16 which is the size of a property pair.

The new set does not allocate memory when the size of the array is reduced.
Furthermore the [[PutObject]] method directly calls the new length setter.

three times which is not optimal.

Properties are changed to a type and value pair instead of a pointer to an internal
representation. Functions such as ecma_op_object_get_[own_]property do not
return with property pointers anymore.

The ecma_op_object_get_[own_]property calls should be phased out from

OS X build regularly reports some 39 warnings falling in 3 major
categories:
* "static function '...' is used in an inline function with
external linkage [-Wstatic-in-inline]": Some semantics around
`inline` have changed between C89 and C99, and gcc and clang seem
to disagree on how strict they should be about them. Solution
chosen is to use `-Wnostatic-in-inline` command line option for
clang.
* "implicit conversion turns floating-point number into integer:
'double' to 'bool' [-Wfloat-conversion]": `if (fmod (..., ...))`
was used at different places, which is not nice anyway, thus the
return value is compared explicitly against `ECMA_NUMBER_ZERO`.
* "format string is not a string literal [-Wformat-nonliteral]":
Console and log port I/O functions have a printf-like interface,
and the default implementations actually pass both format string
and the remaining arguments to a vfprintf. However, clang is
strict about the format string parameter of vfprintf and expects
a literal there. By annotating the port I/O functions with
`__attribute__ ((format (printf, ..., ...)))`, clang will check
the format string being a literal string earlier, when the port
functions are called, and will not complain within them when
vfprintf is called.
(Actually, this has revealed an incorrect format string, which
has been fixed as well.)
(There were also some single conversion errors not listed above.)
The patch was tested on OS X (where all warnings disappeared), but
it should help clang compilation on other OS's as well.

Removing a lot of ECMA_PROPERTY_VALUE_PTR macro calls. The only drawback
is free callbacks for native objects cannot be deleted anymore. Redefining
a free callback is a rare case, so this trade-of is acceptable.

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.
