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.
