Alejandro Colomar 9858133cc6 lib/, src/: snprintf(3) already terminates strings with NUL ...

We don't need to terminate them manually after the call.  Remove all
that paranoid code, which in some cases was even wrong.  While at it,
let's do a few more things:

-  Use sizeof(buf) for the size of the buffer.  I found that a few cases
   were passing one less byte (probably because the last one was
   manually zeroed later).  This caused a double NUL.  snprintf(3) wants
   the size of the entire buffer to properly terminate it.  Passing the
   exact value hardcoded is brittle, so use sizeof().

-  Align and improve style of variable declarations.  This makes them
   appear in this diff, which will help review the patch.
