Drop 'Params' macro in osint files. Modern C compilers accept prototypes, so there was
no need to keep it.
Change /* .. */ comments that extend to end of line in C source files to begin with '//'
Drop use of NEAR in osint. This was needed only for x8086, a processor no longer supported.
Delete conditional assembly symbols no longer needed.
More conditional assembly cleanp
Eliminate MK_MP macro since needed only for x86 NEAR/FAR.
