65c32f6a3b Add parameter names to function declarations. (#1498)
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.

1e99be90c3 Remove redundant extern keywords from function declarations/definitions. (#1495)
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.

0511091e8a Streamline copyright notices across the codebase. (#1473)
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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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.

a2d5acb43c Follow-up refactoring of logging-related parts
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.

ff21777950 Integrate JS parser module better with JRT
The fact that the JS parser had been developed as a separate
component for a while is still visible from some macros that mirror
things from JRT. This patch removes those duplicates and makes the
JS parser rely on jrt.h. (The removed macros are: `PARSER_DEBUG`,
`PARSER_INLINE`, `PARSER_NOINLINE`.)

d953fbb7be Branch opcodes have no result and either they have a stack argument
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.
