Add APIs for checking ASN.1 INTEGERs.

We have several implementations of this internally, so consolidate them.
Chromium also has a copy in net/der/parse_values.cc which could call
into this.

(I'm also hoping we can make c2i_ASN1_INTEGER call this and
further tighten up crypto/asn1's parser, but I see Chromium still has an
allow_invalid_serial_numbers option, so perhaps not quite yet.)

Update-Note: This CL does not change behavior, but I'm leaving a note to
myself to make net/der/parse_values.cc call the new functions.
