Rather than being tied to the Time class the dlLibraryTable libs is now a global
variable in the Foam namespace which is accessable by any class needing to load
dynamic libraries, in particular argList, Time and codeStream.
Currently these deleted function declarations are still in the private section
of the class declarations but will be moved by hand to the public section over
time as this is too complex to automate reliably.
The dynamic code functionality has been generalised so that the names of
the code entries in the specifying dictionary can be set by the caller.
This means that functions which utilise dynamic code but use different
entry names (e.g., codedFunctionObject uses codeExecute, codeEnd,
etc..., instead of code) now function correctly. The differently named
entries now form part of the library hash, and re-building triggers
appropriately as they are modified.
