Mps: fix w3 builds: integrate from master the following:

MPS: fix Windows build of text-executables needing formats, with new 
make-variable FMTTEST, replacing DWTEST and HETEST, and fixing 
awlut.exe build.  (integrate from version/1.106/...@157962)
   (159467)
MPS: fix w3i3mv "all" build with VC6:
1. amsss.c: initialize ambigRoot (uninitialized warning);
2. commpost.nmk: 
2a. drop long-vanished protcv.exe;
2b. mpmss.exe needs MVFF;
2c. locusss.exe had no build rule;
3. finaltest.c: main does not use argc,v so declare as main(void);
4. lockutw3.c: add parens to avoid operator-precedence warning;
5. protocol.h: s/interface/interfaceIn: suspected compiler bug.
(integrate from version/1.106/...@158054)
   (159468)
MPS: attempt to fix w3i3mv "all" build with VC7:
(unknown if these changes are effective, but they should be safe)
1. mpm.c: +1 to array size to make room for terminator of string initializer;
2. testlib.c: disable warning 4702: unreachable code, for va_end.
(integrate from version/1.106/...@158055)
