Jonathan T. Looney dc6a41b936 Add the infrastructure to support loading multiple versions of TCP 
stack modules.

It adds support for mangling symbols exported by a module by prepending
a string to them. (This avoids overlapping symbols in the kernel linker.)

It allows the use of a macro as the module name in the DECLARE_MACRO()
and MACRO_VERSION() macros.

It allows the code to register stack aliases (e.g. both a generic name
["default"] and version-specific name ["default_10_3p1"]).

With these changes, it is trivial to compile TCP stack modules with
the name defined in the Makefile and to load multiple versions of the
same stack simultaneously. This functionality can be used to enable
side-by-side testing of an old and new version of the same TCP stack.
It also could support upgrading the TCP stack without a reboot.
