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.

 * 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 `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` as `clang` and uncomment the line (delete the #) for the line that defines `CC` as `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.
