The documentation of `jerry_get_memory_stats` method was missing
the requirements on what build option or feature is required.

The current module implementation resolves module paths relative to the
current working directory, but paths should be resolved relative to the
currently evaluated module/source.
This requires a change in the jerry_port_normalize_path port API
function, so that it also takes the current module path as an argument.
On the engine side, we now also create a module object for the main
script, so that we can properly identify the base path for other
modules.

This PR is a general cleanup for garbage collection and memory
allocation code paths.
Changes:
* Removed an unnecesary local variable from 'ecma_gc_mark'.
* Refactored 'ecma_gc_run' to have an implicit list head during
iteration, which results in one less condition in the loops,
and changed the loops to use compressed pointers to reduce the
overall amount of compression/decompression.
* Renamed 'jmem_free_unused_memory_severity_t' to 'jmem_pressure_t',
and added additional values.
* Removed 'jmem_free_unused_memory_callback', instead
'ecma_free_unused_memory' is now called directly.
* Reworked 'ecma_free_unused_memory' to handle all code paths related
to 'jmem_pressure_t', and moved all relevant code paths into this
function. This simplifies the code paths in other places.
* Reworked 'jmem_heap_gc_and_alloc_block' to be more streamlined.
* Changed mem-stats to not report unused pool chunks as allocated
memory.
* Created an allocator internal API for allocating/freeing memory blocks
that are not reported as used memory in mem-stats.
* Removed iteration statistics for the jerry allocator from mem-stats,
as they don't provide any actually useful information.

** 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.

* 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.

- Allow command line tools to build together with libfuzzer driver.
Compile everything with `-fsanitize=fuzzer-no-link` to prevent
linking in libfuzzers's `main` symbol in all executables (causing
duplicate symbol errors in command line tools), and add
`-fsanitize=fuzzer` to the libfuzzer driver only.
- Make ASan optional when building with libfuzzer to allow the user
to choose freely from available sanitizers (e.g., UBSan, MSan,
HWASan).
- Stabilize libfuzzer by resetting PRNG seed at every invocation.

In the previous approach `jerryx_port_handler_print_char` was implemented
in by the jerry-default-port. This implementation however required the
jerry-ext handler header file which created a requirement in the
jerry-default-port for the jerry-ext headers.

This patch fixes the following error with Clang-6.0
```
jerryscript/jerry-core/api/jerry.c:1527:71: error: implicit conversion loses integer precision:
'jerry_regexp_flags_t' to 'uint16_t' (aka 'unsigned short') [-Werror,-Wconversion]
jerry_value_t ret_val = ecma_op_create_regexp_object (ecma_pattern, flags);
```
Also change the `jerry_create_regexp` and `jerry_create_regexp_sz` functions' `flags` parameter to `uint16_t` since the values created with `bitwise inclusive OR` are not part of the enum.

- `ERR_SYSCALL` is a legacy that has not been used anymore since
the removal of jerry-libc. This commit removes it from the port
API.
- `ERR_DISABLED_BYTE_CODE` is a (relatively) recent addition to the
fatal code enum. At the time it was added, the documentation has
not been updated. This commit adds the missing documentation.
(Plus, it removes a superfluous `JERRY_UNREACHABLE` from after a
`jerry_fatal (ERR_DISABLED_BYTE_CODE)`.)
Note: As the port API is modified, this is an API-breaking change.

The previous jerry_port interface did not allow timezones to be handled correctly,
even if the host system was up to the task. This PR changes the jerry_port interface
to allow a completely correct implementation to exist, and provides one (for Linux/BSD
systems) in default-date.c.

Removed 'jerry_parse_and_save_literals' and introduced
'jerry_get_literals_from_snapshot' instead which works
on snapshot buffers rather than source code. Added literal
saving feature to snapshot merge in the snapshot command
line tool. Also added missing 'jerry_cleanup()' calls to the
snapshot tool. Improved the console messages of the snapshot

Under the cover of the debugger transport layer, allocation on the
engine's heap has been made available to the public. As there are
actually no restrictions on what the allocated memory can be used
for, the memory management functions better fit in the core part
of the API.

There was quite some confusion about terminology around instances
and contexts. All the docs mentioned external contexts but
functions and types were referring to instances, and the relation
between these two concepts were not clear. This commit keeps
(external) context as the only surviving concept.

The `[jerry|ecma]_char_ptr_t` types are some old legacy that are
used quite inconsistently. Their `[jerry|ecma]_char_t *` variants
are used a lot more often, so it's better to stick to one form
throughout the code base.
