These patches extend FUSE to be able to act as a stacked filesystem. This
allows pure passthrough, where the fuse file system simply reflects the lower
filesystem, and also allows optional pre and post filtering in BPF and/or the
userspace daemon as needed. This can dramatically reduce or even eliminate
transitions to and from userspace.

In order to provide better reviewer suggestions and to introduce fine
grained additional approval permissions, sprinkle some OWNERS files over
the tree.
This essentially grants additional OWNERS permissions in
- net/
- arch/arm*/net
- arch/x86/net
- drivers/net
- fs/crypto
- fs/f2fs
- fs/verity
All other permissions are already covered by ref/meta/config:OWNERS.

For incfs files that were created without a merkle tree, enabling verity
requires building a merkle tree first. Although this is the same logic
as verity performs, it is not that easy to reconcile the two given that
incfs has the merkle tree potentially when verity is not enabled.

Test failure was caused by drop_caches sometimes not dropping a range of
sectors in the middle of a random file. Fix by changing to reading the
file before we populate it, so the cache is not involved. Also by
populating it only on the last test, we test logging on both populated
and unpopulated files.
Rewrite the tests with the new test macros, and make the whole test far
more readable.
Test was taking 100 seconds to run, which was half the total runtime for
all the tests. This was due to the sleeps while reading. Reduce number
of such sleeps by a factor of 10, halving total test runtime.
Also incfs_test would exit with 0 whether tests failed or not. Fix.
