IMAPS struct for icount command

[salva-rczero]

An attempt to use strucs within structs, to avoid hardcode in IMAP_FIRST & IMAP_SIZE.

The key is to avoid to update IMAP_SIZE if you need a new one:

#define IMAP_SIZE \
            ( sizeof(sysblk.imap01) \
            + sizeof(sysblk.imapa4) \
            + sizeof(sysblk.imapa5) \
...

that I forget in my first addition of imape7, imape7T.

So, IMAP_SIZE must to be carefully, and manually, maintained. While sizeof sysblk.imaps is done automatically by the compiler.

I agree that it is not a very frequent change, but after many decades supporting a large installation, I learned that many errors are due to the data structures and not so much to the code.
