    Update to otcl-1.14
    ---

    otcl-1.14 Released Sat Oct 29 2011

    (Major change is to update for tcl-8.5 changes, contributed from Amir
    Habibi (habibi@uci.edu)) TCL 8.5.3 has several fundamental internal and
    API changes that render OTCL's use of its low level data structures and
    API syntactically and semnatically incompatible. The major changes are:
      * Variables are kept in a new internal hashtable type named
        VarInHash. Majority of hashtable API functions do not take this
        into consideration and lead to segmentation faults. Unfortunately
        majority of the potential API functions are defined as static in
        original TCL code under generic/tclVar.c and we have to redefine
        them in OTCL code.
         CallFrame.varTablePtr doesn't any longer refer to a string based
             hashtable. The new type is TclVarHashtable that encapsulates a
             VarInHash type hashtable (table) along with a namespace
             (nsPtr). It doesn't need to be initialized as TCL engin will
             allocate it if a local variable is to be defined.
           + Commands are parsed into object-based and string-based
             functions in Tcl_CmdInfo and clientData is not any longer
             guaranteed to be iof (Proc *) type.
        Changes made in otcl1-13 to make it compatible with TCL 8.5.3 and
        hopefully later versions are as follows: (Referenced line numbers
        are with regards to the new version)
           + 0059-0064: Modified to reflect the change in the CallFrame. it
             also defines TCL_VERSION_8_5_OR_HIGHER to simplify changes.
           + 0069-0083: Define few Tcl_xxx macros to make the changes as
             clean as possible. These macros are defined for pre and post
             TCL 8.5.3
           + 0587-0597: AddMethod is supposed to keep a copy of a
             Tcl_CmdInfo data structure after TCL engine has parsed the tcl
             code. ocd input argument is addded to the prototype to deal
             with object-based ClientData or the (Proc *) of the tcl
             procedure. For internal Object and Class objects only
             string-based information is needed by OTCL. Based on this
             change, calls to AddMethod in the following lines are
             modified: 1418-1423, 1845-1849, 1945, 1954
           + 0609-0612: Apparently TCL calls the delete function on the
             Tcl_CmdInfo and we don't need to call it again otherwise glibc
             panics b/c of double free call on the same pointer. (I didn't
             dig into this one and my fix may cause a memory leak)
           + 0732-0737: ListKeys is used for dumping keys in all hashtables
             and since the variables has is no longer a string hash, this
             functions is slightly modified to reflect this change. Since
             TCL doesn't make VarHash related functions available to
             public, we can't automatically recognize a VarInHash type and
             I resorted to adding a new input argument, isVarHash, to
             explicitly pass the flag to this function. Based on this
             change, calls to Listkeys in the following lines are modified:
             1372, 1388, 1804
           + 0784: Modified to reflect object-based versus string-based
             functions use of clientData and objClientData in Tcl_CmdInfo
             respectively.
           + 0920: VarTablePtr doesn't need to be initialized in TCL 8.5.3
             and the call to Tcl_InitHashTable for older versions is added
             to Tcl_VarHashInitilize macro.
           + 0949-0952: Modified to initialize additional fields in
             CallFrame.
           + 1004: Modified to cover the cases where varTablePtr remains
             null during the lifetime of the object.
           + 1008-1015: Modified to reflect changes in varTablePtr
           + 1021-1035: This block of code is no longer needed as in TCL
             8.5.3 hPtr is removed Var structure and instead VarInHash
             encapsualtes Var and Tcl_HashEntry. (This may need further
             investigation !!!)
           + 1036-137: Modified to cover the cases where varTablePtr
             remains null during the lifetime of the object.
           + 1069-1071: Modified to use macros that deal with different
             ways of initialization of varTablePtr in TCL 8.5.3 and older
             versions.
           + 1208-1210: Modified to use macros that deal with different
             ways of initialization of varTablePtr in TCL 8.5.3 and older
             versions.
           + 1211: Modified to clarify the assignment. This is not related
             to changes for TCL 8.5.3
