Porting extensions to Tcl 9

AK (2023-11-14) Seeing a number of Replaced package require Tcl 8.X with package require Tcl 8.X- notes I believe that I should note that there might be a better way than this. While going from 8.X to 8.X- opens the package to 9, it also opens it to 10, 11, etc. A more restricted way would be to go to package require Tcl 8.X 9. The two requirements, 8.X, and 9 are OR-ed. The command accepts the Tcl version if it matches at least one of the requirements. With this change the package is opened to 9, but not beyond. This is not my idea. It came from Rolf Ade in his work on making Tcllib ready for Tcl 9. I had to reread the package manpage to understand.

PO - 2023-11-13

This page is the summary of my experiences trying to port the Tcl packages or programs supported by BAWT to Tcl9.

The following Tcl and Tk versions have been used for the porting tests:

Tcl9.0b1	9.0b1+9f0391c078075f932d389334cb30ca66b3215e477de6c0c9f4cd95b6f02d39df.gcc-702
Tk8.7b1	8.7b1+6e002715a6698c676a3e99eafaa1a0d68042de2b4d6a686c759a016c3bb05448.gcc-702.utf-16.win32

Table Packages lists all packages looked at and their current status.
Table Changes in Tcl summarizes all changes done at the Tcl level for all packages.
Table Changes in C summarizes all changes done at the C level for all packages.
All other tables summarize the changes done for each individual package or program.

Please feel free to add your experiences, additions and comments.

Packages

This table summarizes the status of the package ports.

The columns show the folllowing information:

Library: The name and a link to the package home page.
Start version: The version number and a link to the source of the package as used for start of the porting.
Ported version: The version number and a link to the source of the ported package. If entry is Worked, then the Start version is working. If entry is N/A, I either did not look at the package or it was too much effort.
Build: The modified package could be compiled with Tcl 9.
Require: A package require suceeded for the package with Tcl 9.
Bawt Test: The simple BAWT test program for this package works with Tcl 9.
Responsible: Add a name or link, if you are the maintainer or feel responsible for this package.
Comments: Short comments regarding this package. Add longer comments at the end of the table.

Added Tcl_Size related definitions, if TCL_SIZE_MAX is not defined
Replaced ìnt with Tcl_Size in functions having Tcl_Size as output parameter
Replaced NULL or 0 with (Tcl_Size *)NULL in functions having Tcl_Size as input parameter
Replaced NULL with (char *)NULL in calls of function Tcl_AppendResult or Tcl_SetErrorCode

Additional comments:

DKF: Note that Tcl_SaveResult() has basically been deprecated since Tcl 8.5 because it doesn't handle the full state of the interpreter (and can't; not enough space in the Tcl_SavedResult structure definition and that's caller allocated; by comparison, Tcl_InterpState is an opaque handle and has its definition entirely managed by Tcl's internals). Unless you need the code to still work in Tcl 8.4 and before, you should update to use the new API. Tcl 9.0 just removes that deprecated API; Tcl 8.5 and 8.6 were the transition period (over a decade).

chrstphrchvz: Note that casting the NULL sentinel for Tcl_AppendResult()/Tcl_SetErrorCode() is not for Tcl 9 readiness, but rather something that should be done anyway for portability.
