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.

Used a custom clang-tidy check to create the bulk of the change.

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.

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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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.

Remove ecma_completion_value_t, and add an extra bit to
ecma_value_t to represent errors. From the long list of
completion types only normal and error remained.

 - components renaming and moving:
   - liballocator -> mem;
   - libcoreint -> vm;
   - libecmaobjects -> ecma/base;
   - libecmaoperations -> ecma/operations;
   - libecmabuiltins -> ecma/builtins;
   - libjsparser -> parser/js;
   - libintstructs -> parser/collections;
   - liboptimizer -> parser/js;
   - libperipherals -> ../plugins/lib_device_stm;
   - libruntime -> jrt;
 - generated.h now is created as intermediate during build;
 - benchmarks -> tests/benchmarks;

Converting ecma_completion_value_t to class derived from ecma_value_t with additional field with for completion type and related operations.

Completion value are now returned through ecma_completion_value_t &ret_value argument.

Original ecma_value_t is renamed to ecma_value_packed_t and is used for on-heap storage.
Copy and move constructors, move assignment operator of ecma_value_t are not created.
New ecma-value return convention is introduced: ecma-values are now returned through ecma_value_t &ret_val argument.

Introducing ecma_is_string_magic, ecma_init and ecma_finalize interfaces, 'magic-string' container type for ecma-strings. Renaming ecma_is_magic_string to ecma_is_zt_string_magic. Moving magic-string related routines to ecma-helpers-string.c.

Moving Global object related routines to libecmabuiltins component. Introducing ecma_init_builtins and ecma_finalize_builtins routines.

Replacing const ecma_char_t* with ecma_string_t*; supporting number-represented string in ecma_string_t.

Style fixes in liballocator, libecmaobjects, libecmaoperations: now lines are not longer than 120 characters.

Style fixes in libecmaoperations: space between function name and opening parenthesis, no space after opening parenthesis/before closing parenthesis. By mistake, the changes weren't commited with 8081e5cdb38ad0f9789a89c92362fc73a716d85c.

Implementing object model, memory allocators finalization routines. Adding assertion that all memory was freed before exit.

Renaming ecma_CompletionValue_t:: completion_type to type, completion_value to value.
Introducing ECMA_TARGET_ID_RESERVED value of ecma_CompletionValue_t::target when it is unused.
Adding ecma_Reference_t type for ECMA-reference.
Introducing some constructors and helpers for ecma-values.
Introducing ecma_FindNamedProperty helper.
Removing ecma_SyntacticReference_t type.
Implementing ecma operation GetIdentifierReference.
Stubs and partial implementation for GetValue, SetValue, lexical environment operations (HasBinding, etc.).
