Rename bn->top to bn->width.

This has no behavior change, but it has a semantic one. This CL is an
assertion that all BIGNUM functions tolerate non-minimal BIGNUMs now.
Specifically:

- Functions that do not touch top/width are assumed to not care.

- Functions that do touch top/width will be changed by this CL. These
  should be checked in review that they tolerate non-minimal BIGNUMs.

Subsequent CLs will start adjusting the widths that BIGNUM functions
output, to fix timing leaks.
