After a Tcl_SetObjResult, don't do a Tcl_TransferResult to the same interpreter
Stop [glob] complaining about empty list result.  Continue support for
a no-op -nocomplain option, but don't document it.  Old script support only.
Re-fix failing load-3.2 test.  The right way this time.
Remove all maintenance of a string result in the Interp.
Initialize legacyFreeProc with invalid value: This will result in
a crash immediately, when an extention tries to call it, in stead
of crashing some time later....
Remove some more legacy regarding accessing interp->result
Remove obsolete functions Tcl_GetDefaultEncodingDir and Tcl_SetDefaultEncodingDir
Cleaning up some of the internals of TIP #280.

Replaced the hashtables keyed by pointers to Proc and ByteCode
structures and providing associated information with fields in the
structures, direct pointers to the information. The change makes the
information accessible through a single pointer dereference instead of
a hashtable search.

Some information (Tcl_Obj* related) could not be inlined in this way
and likely requires a larger reworking of parser and script
structures.
