Fix buffer overflows

[jserv]

• display.c: stpstatus[64] overflow via strcat chain; enlarged to 256, replaced with bounded snprintf
• main.c: lotargv alloca undercount; first-pass counted 1 per option but pass-through options with args need 2 slots; count += 2 per iteration
• showme.c: clear_showme writes past MAX_SHOWME arrays; add count guard
• coffsyrup.c: Relocation boundary check allows 4-byte write past section buffer; account for sizeof(uint32_t) in range check Symbol index off-by-one; change > to >= for f_nsyms bound

Hmm, I think you're right about the argument parsing - nice catch!

The stpstatus patch doesn't look correct, I think it's uninitialized when the first strcat() happens, so you can't strlen it? Maybe you misread it and thought it was strcpy?

No, I'm wrong - I think it is always initialized, hmm - oops, maybe you're right.
