Implement realm object and support realms for built-ins and JS functions (#4354)
- Type for realm objects is introduced (ecma_global_object_t)
- Realm reference is added to built-in objects and ECMAScript functions
- Resolving built-ins, global environments, and scopes require realm object
- Unnecessary global object accesses are removed from the code

Missing: external functions and static snapshot functions have no realm reference

Fix lexical scoping between scripts (#3558)
This change fixes the handling of lexical blocks when executing multiple
scripts, and also fixes a few issues with module environments.

After this change, all script files will run in the same context and
will have access to lexically scoped global variables of previous
scripts, and module environments will no longer have a bound global
'this' value.

The REPL implementation in main-unix is also fixed to correctly handle
lexically scoped variables.

Fixes #3561.

01ecc7bb7b Rework usages/naming of configuration macros [part 2] (#2903)

** Renamed CONFIG_ECMA_LCACHE_DISABLE to JERRY_LCACHE.
** 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.
** Renamed JERRY_ENABLE_LINE_INFO to JERRY_LINE_INFO.
** Renamed JERRY_ENABLE_LOGGING to JERRY_LOGGING.
** Renamed JERRY_ENABLE_SNAPSHOT_EXEC to JERRY_SNAPSHOT_EXEC.
** Renamed JERRY_ENABLE_SNAPSHOT_SAVE to JERRY_SNAPSHOT_SAVE.
** Renamed JERRY_SYSTEM_ALLOCATOR to JERRY_SYSTEM_ALLOCATOR.
** Renamed JERRY_VM_EXEC_STOP to JERRY_VM_EXEC_STOP.
** Renamed JMEM_GC_BEFORE_EACH_ALLOC to JERRY_MEM_GC_BEFORE_EACH_ALLOC.
** Renamed JMEM_STATS to JERRY_MEM_STATS.
** Renamed PARSER_DUMP_BYTE_CODE to JERRY_PARSER_DUMP_BYTE_CODE.
** Renamed REGEXP_DUMP_BYTE_CODE to JERRY_REGEXP_DUMP_BYTE_CODE.
* Recursion check changes:
** Renamed REGEXP_RECURSION_LIMIT to JERRY_REGEXP_RECURSION_LIMIT.
** Renamed VM_RECURSION_LIMIT to JERRY_VM_RECURSION_LIMIT.
* 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:

40f7b1c27f Rework usages/naming of configuration macros [part 1] (#2793)
There are quite a few configuration macros in the project.
As discussed in the #2520 issue there are a few awkward constructs.

Main changes:

* Renamed all CONFIG_DISABLE_<name>_BUILTIN macro to JERRY_BUILTIN_<name> format.
* The special JERRY_BUILTINS macro specifies the basic config for all es5.1 builtins.
* Renamed all CONFIG_DISABLE_ES2015_<name> to JERRY_ES2015_<name> format.
* The special JERRY_ES2015 macro specifies the basic config for all es2015 builtins.
* Renamed UNICODE_CASE_CONVERSION to JERRY_UNICODE_CASE_CONVERSION.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
* All options (in this change) can have a value of 0 or 1.
* Renamed ENABLE_REGEXP_STRICT_MODE to JERRY_REGEXP_STRICT_MODE.
  JERRY_REGEXP_STRICT_MODE is set to 0 by default.
* Reworked CONFIG_ECMA_NUMBER_TYPE macro to JERRY_NUMBER_TYPE_FLOAT64 name and now
  it uses the value 1 for 64 bit floating point numbers and 0 for 32 bit floating point
  number.
  By default the 64-bit floating point number mode is enabled.
* All new JERRY_ defines can be used wit the `#if ENABLED (JERRY_...)` construct to
  test if the feature is enabled or not.
* Added/replaced a few config.h includes to correctly propagate the macro values.
* Added sanity checks for each macro to avoid incorrectly set values.
* Updated profile documentation.
* The CMake feature names are not updated at this point.

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.
