Support syntax error feedback in parser.

Browse Source 
Now, parser correctly finishes parse procedure if syntax of source code is incorrect (syntax correctness is indicated using return value):
 - parser-internal memory management is performed using jsp_mm_alloc / jsp_mm_free;
 - upon detection of incorrect syntax, all parser-allocated memory regions are deallocated using jsp_mm_free_all and parse finishes with corresponding return value.
