Clang 10 turns on -Wimplicit-int-float-conversion, and on 64-bit
platforms this issues a warning that implicit conversions to double
from Size and unsigned long "may lose precision".
This commit adds casts to (double) for all such conversions. The loss
of precision is either impossible in practice (because a double can
represent all integers up to 2**53, which is about 9 petabytes, well
beyond the addressing capabilities for current CPUs), or else
acceptable, because we are accumulating an approximate quantity like
"collection work" or "fill size" (that has to cope with loss of
precision due in any case), or computing a threshold like the spare
commit limit where it is acceptable for it to be somewhat approximate.
Publish minor changes to readme and configure files in main directory.
Main directory and code directory licence texts are now fully updated.

Speed up mpsicv by reducing number of objects and by only running the test once (there's no inlined mps_tramp any more).

* Refactor nmake files so that a compiler-specific makefile is included; move Microsoft Visual C-specific options to mv.nmk.
* Add nmake files for Pelles (w3i3pc.nmk and pc.nmk).
* Rename spw3i3mv.c to spw3i3.c and spw3i6mv.c to spw3i6.c since these are also used by Pelles C.
* Make reasonable changes to the source code to avoid warnings from Pelles C:
** check results of function calls;
** avoid useless return values;
** undef max before defining it;
** ensure printf formats are checkable;
** move notreached() assertions to the end of blocks;
** suppress warnings in cases where the code shouldn't be changed ("Unreachable code", "Inline assembly code is not portable", "Structured Exception Handling is not portable").

1. "make test" now reports the name of the test case before running it, so that when you look back through the test output you can see which test case failed.
2. "make test" now collects the standard output from all the tests to a log file in /tmp, so that this does not clutter the user's terminal, and so that nothing is lost if the output exceeds the terminal's scrollback.
3. Each test case now prints a success message ("Conclusion: Failed to find any defects.") to standard output (not standard error) so that these messages do not clutter up the terminal when running "make test".
4. Each test case now uses its result code (not the printed message) to indicate whether it succeeded or failed.
5. More of the diagnostic messages from the test cases now start by printing argv[0] so that it is easier to tell which test case was running.

Now that we're recommending inlining with client code and optimising with -O2 or -O3, we can't afford any bug introduced by the strict aliasing rule.
