- generic/nsfAPI.h: Renamed the [::nsf::current next] subcommand to [::nsf::current nextmethod] - library/xotcl/library/xotcl2.tcl: Accordingly, the xotcl::self emulation maps [self next] to [current nextmethod] - tests/disposition.test, tests/methods.test, tests/submethods.test, tests/tcloo.test: Changed the few occurrences of [current next] to [current nextmethod] - tests/introspection.test: Added some basic tests on the expected behaviour of [::nsf::current nextmethod]

- generic/nsf.c: For "tolerating" hidden objects, I verified the various occurrences of conitional branching based on the cmd's epoch counter. While most occurrences are not concerned (cmds of nested objects, or simply non-object commands), I identified three relevant spots: a) In NsfProcAliasMethod(), invalidating and rebinding the alias target command (including hidden objects as alias pointers) is based on the epoch counter; b) in MixinSearchProc() the lookup of mixed-in methods is affected; c) using CmdListRemoveEpoched() (as the name says), "deleted" commands are identified by looking at the cmd epoch and sorted out from mixin lists computed for precedence lists. I corrected cases b) and c), with the fixes being covered by accompanying tests; a) turned out to be consistent with alias rebinding behaviour for [rename]. While we could correct a) for hidden cmd awareness, this would have to be done for the likeminded alias + [rename] as well. - generic/nsf.c: Renamed CmdListRemoveEpoched() to CmdListRemoveDeleted() - tests/interp.test: Added tests on b) and c), as well as hiding globally namespaced procs and objects as alias targets (merely for documenting the behaviour).

- library/lib/test.tcl: Stop using [exit] to interrupt test suite runs upon failure conditions. This led to unwanted garbage due to the non-returning character of [exit].

- generic/nsf.c: After several takes, adding support for basic handling of hidden and re-exposed objects in the sense of [interp hidden|hide|expose]. I wanted to make sure that NSF does not crash upon basic hiding/exposing operations (see tests/interp.test) and guarantees that hidden/re-exposed objects are properly handled when cleaning up object systems, i.e., the destructors are called and physical deletion is performed. [interp hidden|hide|expose] is challenging for NSF (as well as TclOO) because they way it is implementing effectively modifyies command names *without* providing any calling back to trace these changes (as for renames). As a consequence, object and command names start to diverge once an object has been hidden or re-exposed. As the changes affect the cleanup machinery in ObjectSystemsCleanup() & friends, I verified for leaks by running valgrind; no leaks were found running destroy.test and interp.test. - tests/interp.test: A test suite that covers basic scenarios of hiding and exposing objects. - Makefile.in: Registering interp.test with make env
