6432e4d7cf Replace convert_string_to_token_transform_escape_seq with lexer_transform_escape_sequences that outputs transformed charset to specified buffer, instead of creating token from the charset. 
Also the commit introduces lexer_convert_escape_sequence_digits_to_char, adds 'lexer' prefix to convert_single_escape_character and replaces character constants with corresponding LIT_CHAR_* definitions in the function.

dc095bb902 Enhancement of argument list parsing loop: removing break / continue operators, so that every iteration passes start and end of loop body. 
The change makes possible simple notification of byte-code generator about start / end of byte-code generation for an argument.
As register values are not passed between byte-code sequences that prepare different arguments, the change would make possible for byte-code generator to reuse registers allocated for the code sequences.

a4e54e736e Support syntax error feedback in parser. 
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.
