Now that the new CMake build system is encouraging us to lay out the code like a set of libraries, it seems like a good idea to make them look more _like_ libraries, by putting things into separate modules as far as possible. This fixes several previous annoyances in which you had to link against some object in order to get a function you needed, but that object also contained other functions you didn't need which included link-time symbol references you didn't want to have to deal with. The usual offender was subsidiary supporting programs including misc.c for some innocuous function and then finding they had to deal with the requirements of buildinfo(). This big reorganisation introduces three new subdirectories called 'utils', one at the top level and one in each platform subdir. In each case, the directory contains basically the same files that were previously placed in the 'utils' build-time library, except that the ones that were extremely miscellaneous (misc.c, utils.c, uxmisc.c, winmisc.c, winmiscs.c, winutils.c) have been split up into much smaller pieces.

* Convert a size_t value to int, by saturating it at INT_MAX. Useful

* specifier expects an int in the variadic argument list, but what
|
|
* you have is not an int but a size_t. This method of converting to
|
|
* int will at least do something _safe_ with overlong values, even if

* (due to the limitation of printf itself) the whole string still
