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.

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the codebase with contributor-specific copyright notices which have a higher maintenance overhead and tend to get outdated quickly.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

Short summary of the changes:
- The ecma_reference_t is removed, and its helper functions are deleted.
- The delete operation does not depend on ecma_reference_t anymore.
- A new resolve function is added which returns the current value
of a named binding in the context chain.
- The vm_op_set_value does not perform type conversions when its arguments
has the appropriate types.

The new literal storage keeps ecma strings rather than having a
custom string implementation which duplicates the string management
routines. Conversions between string implementations are eliminated
which improved the performance by 4%.

The implementation is simplified and optimized
resulting the removal a large amount of code.

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.

- parser is now non-recursive (i.e. parse function is not called recursively in any case);
- byte-code is now more compact:
- constants are now not immediately dumped upon occurence, but later - where necessary;
- assignments are combined with unary / binary operations;
- binary operations are encoded more compactly in many cases;
- byte-code arrays are now allocated separately for each scope (so, GC of the scopes now becomes possible);
- byte-code is dumped directly into corresponding byte-code arrays:
- linked lists of op_meta are not now used for main code of a scope.

For functions with the optimization applied:
- vm puts arguments values immediately to registers without putting them to variables in lexical environment;
- number of arguments is extracted from corresponding 'reg_var_decl' instruction's argument;
- for functions that also don't have local variables, lexical environments are not created.

ECMA-stack is related to VM and is not related to ECMA component, except for GC.
Dependency between vm-stack and GC would be solved after GC would be extracted to a separate compoment.

Introducing opcode_call_flags_t for argument of the new meta opcode, currently with two flags: 'have this argument' and '"direct call to eval" form'.
