Also fixed two bugs in the process:
is_pseudo_filename was not previously checking for .log, so an attempt
to create a .log would succeed.
All ioctls could be called on all files. ioctls now set on the correct
files.

Since INCFS_IOC_GET_FILLED_BLOCKS potentially leaks information about usage
patterns, and is only useful to someone filling the file, best protect it in
the same way as INCFS_IOC_FILL_BLOCKS.
Add useful field data_block_out as well

When read log is 0 sized, we still need to init the wait queue to avoid
kernel panics if someone does decide to poll on the read log.
Test: Added test for this condition, incfs_test crashes
With fix, incfs_test doesn't crash

Filling blocks is not equivalent to writing a file, since they are
constrained by the root hash. selinux policy may wish to treat them
differently, for instance.
