Patch 8.2.4081
Problem: CodeQL reports problem in if_cscope causing it to fail.
Solution: Use execvp() instead of execl(). Merge the header file into the
source file. (Ozaki Kiichi, closes #9519)
Files: Filelist, src/Make_cyg_ming.mak, src/Make_mvc.mak,
src/Make_vms.mms, src/Makefile, src/if_cscope.c, src/if_cscope.h,
