Major cleanup of mkfs block processor

This commit tries to make the block and fragment processing code a
lot more readable by simplifying it as follows.

The following pattern is used repeatedly:
 - Try to compress a block
 - Write the compressed if smaller (the original otherwise) to a file
 - Print errors on the way
 - Set the magic (1 << 24) flag if we wrote the original
 - Increment the super block byte counter

=> Move that to a seperate function called "write_compressed"

=> Move the code to grow the fragment table is moved to a seperate function.

=> Clearing the fragment buffer is pointless, so remove that

The add_fragment/add_block functions are now trivial
=> Merge them into process_file
=> Global block counter no longer needed, so remove that too
