Merge pull request #533 from Interlisp/nhb-rewrite-version-parser-v2

Extensive rewrite of various parts of the file name/version handling code. Converts a lot of unsafe string handling functions to safer variants. Passes buffer sizes in various places to enable overflow checks. Removes some unused variable declarations. Updates comments. Improves performance with alarm timeout setting when sequences of alarm set/cancel operations are performed. Adds GETFILEINFO processing for INODE_LO and INODE_HI attributes.
Removes assigned-but-not-used rval in DSK_getfilename and redundant test of current_len in conc_dir_and_name

 ## Development Platforms

-We are developing on FreeBSD, Linux, macOS, and Solaris currently
-on arm7l, arm64, PowerPC, SPARC, i386, and x86_64 hardware.
+Development has been primarily on macOS, FreeBSD, and Linux, with testing on Solaris and Windows.

-* The build will (attempt to) detect the OS-type and cpu-type. It will build binaries `lde` and `ldex` in `../ostype.cputype` (with .o files in `..ostype.cputype-x`. For example, Linux on a 64-bit x86 will use `linux.x86_64`, while macOS 11 on a (new M1) Mac will use `darwin.aarch64`.
-* If you prefer using `gcc` over `clang`, you will need to edit the makefile fragment for your configuration (`makefile-ostype.cputype-x`) and comment out the line (with a #) that defines `CC` for `clang` and uncomment the line (delete the #) for the line that defines `CC` for `gcc`.

+* If you want to do your own loadups to construct sysout files (see [the Medley repository](https://github.com/Interlisp/medley) for details), you also need the `ldeinit` binary, which you can build using `./makeright init`.
+
+### Building with CMake
+We provide a `CMakeLists.txt` which provides mostly matching build capabilities to the `make` setup.
+CMake options are provided to control the configuration of the Maiko executables:
+* MAIKO\_DISPLAY\_SDL: [OFF], 2, 3 - selects display subsystem SDL of version specified
+* MAIKO\_DISPLAY\_X11: [ON], OFF - selects X11 display subsystem
+* MAIKO\_NETWORK\_TYPE: [NONE], SUN\_DLPI, SUN\_NIT, NETHUB - network subsystem access
+* MAIKO_RELEASE: [351], various - see `maiko/inc/version.h`
+
+While SDL3 is selectable, the Maiko code has not yet been updated to work with the SDL3 API.

 ### Building For macOS

-* Running on macOS requires an X server, and building on a Mac requires X client libraries.
+* Building/running on macOS requires either an X server and X client libraries or the SDL2 library.
 An X-server for macOS (and X11 client libraries) can be freely obtained at https://www.xquartz.org/releases
-
-### Building for Windows 10
-
-Windows 10 currently requires "Docker for Desktop" or WSL2 and a (Windows X-server).
-See [Medley's README](https://github.com/Interlisp/medley/blob/master/README.md) for more.
