| | | | [0e92c404f19ede5b2eb06e6db27647d3138cc56|0e92c404f1]: The only place where a type of &tclByteArrayType can be trusted is when determining its length, because the character length of a (UTF-8) string is always equal to the byte length of the byte array.

| | | | | | | | | | Make TclFreeCompileEnv smarter about cleanup so all callers do not have to be. Revise TclSetByteCodeFromAny() so that when hookProc raises an error, bytecode is not generated. This was rumored to cause crashes.

The code here is much simpler (trimmed down) compared to the head as the 8.4 branch is not bytecode compiling whole files, and doesn't compile eval'd code either. Reworked the handling of literal command arguments in bytecode to be saved (compiler) and used (execution) per command (See the TCL_INVOKE_STK* instructions), and not per the whole bytecode. This removes the problems with location data caused by literal sharing in proc bodies. Simplified the associated datastructures (ExtIndex is gone, as is the function EnterCmdWordIndex).
