Changing from t3b to t4b signer

[Edward Lewis]

There is a change in the way 8.2.2.-t3b's signer and 8.2.2.-t4b's signer
parse the SIG record.  The impact of this is that a signed master file
generated by t3b ('s signer) will produce parsing errors when t4b reads it.
(Specifically, reporting that the TTL field won't fit into 8 bits, for
larger sizes of TTL's.)

The fix to this is to delete all SIG records from the master file (via a
text editor) and then use the file as input.  Don't worry about the NXT or
other records, the signer will make whatever other changes are required.

If you have signed data with t3b but don't "recycle" your signed file, or
you are signing a freshly made master file (without signatures), you won't
see the change made.
