Provided a Tcl_DupInternalRepProc() function for Tcl_ObjType "nsfParam"

Recent versions of Tcl9 call Tcl_DupInternalRepProc() for Tcl_ObjType

"nsfParam", which was a placeholder function before, leading to a

Tcl_Abort(). The provided implementation provides now a basic logic

for "duplicating" internal representations of parameter lists based on

refcounts (somewhat similar to ProcBodyDup), but it has to be tested

further, with a proper test case.

The call of the Tcl_DupInternalRepProc function happens so far during

the startup of NaviServer compiled with Tcl9. It might be necessary to

overthink the competing logics of the "canDelete" member and the

reference count. For now, the intention is to get the NaviServer +

Tcl9 regression test stop from aborting.

Fixed warnings detected with branch "disabletcl8api"

The Tcl9 native interface is based on "Tcl_Size" instead of "int", but

the default mode hides these differences via some macro-magic. Typical

such cases are API calls like:

Tcl_ListObjLength(interp, methodObj, &length);

Tcl_ListObjGetElements(interp, methodObj, &oc, &ov)

The macro-magic queries the size of the provided parameters and uses

the old or new interface depending on it (while hiding some more

potential problems, a compiler can detect). The branch

"disabletcl8api" removes the macro-magic and reveals the potential

problem areas, where the code is still depending on the old 32bit

interface.

This commit fixes such cases and the collateral damage.

Provide support for TIP 627 (Tcl 8.7a6+ and Tcl 9)

TIP 627 introduces support for > 2^31 elements in object vectors

(e.g., number of words in a single Tcl command). For details, see

https://core.tcl-lang.org/tips/doc/trunk/tip/627.md

To provide also backwards compatibility, this change uses the macros

TCL_COMMAND_OBJPROC, TCL_CREATEOBJCOMMAND, TCL_NRCALLOBJPROC,

TCL_NRCREATECOMMAND, TCL_OBJCMDPROC_T, and TCL_OBJC_T.

New feature: added support for return value checker for nsf::proc

One can now specify "-returns ...." in nsf::proc commands the same way

as in nx/XOTcl2 methods.

nsf::proc ... /procName/ /arguments/ ?-returns /valueconstraint/? /body/

When return value checkers are defined, these are returned by the

usual introspection interface.

% nsf::proc ::foo {-a:integer} -returns integer {return 1}

% nsf::cmd::info definition ::foo

::nsf::proc ::foo -a:integer -returns integer {return 1}

% nsf::cmd::info returns ::foo

integer

The regression test was extended to cover these cases.

Fix bug, where Tcl's "string is" checker modified result, when used as a return value checker

The new code saves and restores the original result value.

The regression test was extended.

Many thanks to Antonio Pisano for pointing out this issue.

Bug fix: include alias to object in "info methods -path"

Previously, it was not possible to define an alias to an object for

NaviServer, since it was not returned by "info methods -path" and

was therefore not included in the blueprint.
