Fixup JMEM_HEAP_STAT_xxx definitions (#2509)
- Get the macro definition indentations right.
- Define some of the macros only if system allocator is not in use.
- Ensure that macros with arguments don't cause unused variable
  warnings even if memory statistics is disabled.

Reorganize heap context related elements (#2500)
- Moved global context's `JMEM_HEAP_SIZE` to jcontext.h as external
  context's heap size is declared there, too.
- Moved the assert on `jmem_heap_t` vs `JMEM_HEAP_SIZE` to jcontext.c,
  as both entities are declared in the corresponding header.
- Removed superfluous checks on `JMEM_HEAP_SIZE` as it is not a
  publicly configurable macro (opposed to `CONFIG_MEM_HEAP_AREA_SIZE`).
- Ensured that all definitions of and references to `jmem_heap_t`,
  `JERRY_HEAP_CONTEXT`, `JERRY_HEAP_SIZE`, and `JERRY_HEAP_AREA_SIZE`
  are guarded by `#ifndef JERRY_SYSTEM_ALLOCATOR`, as they are
  meaningless if the system allocator is used.

The commit also contains some stylistic changes in jcontext.h

58c568a68f Revisit unused global functions in jerry-core (#2450)
There are some leftover global functions in the code that are not
referenced at all anymore. These functions are removed by this
patch.

There are also some global functions that are only used in their
own modules. These functions are made static by this patch.

d5593c12b4 Maintenance and merging of Valgrind and Valgrind-Freya code paths (#2362)
None of the code paths have been tested for long and especially the
Freya code paths have been long abandoned. This patch:
- Merges Valgrind-Freya into Valgrind code path (there should be no
  need to choose between them, Valgrind should work just fine).
- Removes leftover code (`VALGRIND_FREYA_CHECK_MEMPOOL_REQUEST` and
  `valgrind_freya_mempool_request`).
- Adds `JMEM_` prefix to Valgrind-related macros (to correctly
  leave the `VALGRIND_` prefix to Valgrind).
- Moves the definition of the Valgrind-related macros to a common
  header to avoid duplication.

Note: Adding a CI job to perform Valgrind Memchecks is left for
follow-up as it turns out to be excessively slow (>50 mins for a
`--jerry-tests --jerry-test-suite` run, and even a simple
`--jerry-tests` may get terminated prematurely because of timeout
issues).

Cleanup code around JERRY_UNREACHABLEs (#2342)
`JERRY_UNREACHABLE`s often signal code structure that could be
improved: they can usually either be rewritten to `JERRY_ASSERT`s
or eliminated by restructuring loops, `if`s or `#if`s. Roughly,
the only valid occurences are in default cases of `switch`es. And
even they can often be merged into non-default cases.

Moreover, it is dangerous to write meaningful code after
`JERRY_UNREACHABLE` because it pretends as if there was a way to
recover from an impossible situation.

This patch rewrites/eliminates `JERRY_UNREACHABLE`s where possible
and removes misleading code from after them.

65ae949dc3 Add jerryscript-compiler.h public header to cover compiler incompatibilities (#2313)
In general, public headers should not have compiler-specific
constructs but both the core and the port headers have attributes,
which are non-standard. It's better to factor out such constructs
to a common place (a new header) and hide them behind macros, which
can then be defined on a per-compiler basis.

This patch moves the existing definitions of function attributes and
likely/unlikely builtins to the new header. At the same time, it
unifies the names of these attribute defines and where they are
used. Moreover, it touches on jerry-main and removes the uses of
`__attribute__((unused))` entirely and replaces them with the
elsewhere used `(void) ...` pattern.

0f4edbe580 Ensure that const and pure function attributes are used properly (#1739)
Some functions were incorrectly marked as const but were pure only
(or not even pure). Some functions were marked as pure but
qualified as const. Some functions were not attributed at all but
qualified either as pure or const. Some functions had attributes
at definition but not at declaration. This commit fixes these
inconsistencies.

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.

8edab96162 Fix JMEM_HEAP_END_OF_LIST for pointers larger than 32 bits
For 64 bit pointers, 0xffffffff as end-of-list marker pointer does
not work, as the marker is expected to be greater than the start
address of the heap area (and also max 0xffffffff away), but on 64
bit systems, the heap can start on higher addresses, i.e., above
0x100000000.

This patch changes JMEM_HEAP_END_OF_LIST from pointer to offset.

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.

3a78d30897 Introducing global context.
Currently the static variables of the allocator are moved into a
global structure.

The future plan is supporting multiple context models with different
advantages and disadvantages. Users can select the most appropriate
context model for their own use case. This context model must be
selected at compile time using compiler defines.

Currently only one model is implemented, which will be the default
context model: the context is stored in global variables, so only
a single context is available which always exists.
