* Don't ever allow UTF-8 sequences of more than 4 characters to be generated ↵jan.nijtmans2016-08-301-1/+1
|\ | | | | | | | | or parsed, even when TCL_UTF_MAX>4: According to current Unicode standard, a byte string of >4 characters can never form a single UTF-8 character. And a few minor micro-optimizations related to UTF-8 handling.

* Eliminate AuxDataType table: since this table only contains 4 constant ↵jan.nijtmans2015-12-151-2/+0

| | | | | internal Obj types. On most platforms this doesn't make a difference, as (void *) and (long) generially have the same size. The only exception where it makes a difference is win64, as we can now store 64 bits in this field in stead of only 32 bits, exactly what the processor is optimized for.
