Jim Harris 40c911b957 blob: add used blobid bit array for valid blobids
This can be used for two purposes:

1) more quickly iterate the blob list, avoiding
   metadata pages that are valid but not the first
   page in the blob's metadata list
2) close races between delete and open operations -
   now we can clear the bit in the blobid bit array
   when the delete operation is in progress, ensuring
   no one else can try to open the blob
