DECSCUSR+DECRQSS: treat hollow cursor as a block cursor

Browse source 
If the user has configured cursor.style=hollow, make DECSCUSR 1/2 set
the cursor to hollow rather than block, and make DECRQSS DECSCUSR
respond as if cursor.style=block.

The idea is to not expose the hollow variant in DECSCUSR in any way,
to avoid having to extend it with custom encodings.

Another way to think about it is this is just a slightly more
discoverable way of doing:

    cursor.style=block
    cursor.block-cursor-is-hollow=yes
