More void, fewer clang warnings in util/ego Most warnings are for functions implicitly returning int. Change most of these functions to return void. (Traditional K&R C had no void type, but C89 has it.) Add prototypes to most function declarations in headers. This is easy, because ego declares most of its extern functions, and the comments listed most parameters. There were a few outdated or missing declarations, and a few .c files that failed to include an .h with the declarations. Add prototypes to a few function definitions in .c files. Most functions still have traditional K&R definitions. Most STATIC functions still don't have prototypes, because they have no earlier declaration where I would have added the prototype. Change some prototypes in util/ego/share/alloc.h. Functions newmap() and oldmap() handle an array of pointers to something; change the array's type from `short **` to `void **`. Callers use casts to go between `void **` and the correct type, like `line_p *`. Function oldtable() takes a `short *`, not a `short **`; I added the wrong type in 5bbbaf4. Make a few other changes to silence warnings. There are a few places where clang wants extra parentheses in the code. Edit util/ego/ra/build.lua to add the missing dependency on ra*.h; I needed this to prevent crashes from ra.
