[PATCH v3 0/9] Split fsverity-utils into a shared library

[Jes Sorensen <jes.sorensen@gmail.com>]

From: Jes Sorensen <jsorensen@fb.com>

Hi,

This is an updated version of my patches to split fsverity-utils into
a shared library. This version addresses most of the comments I
received in the last version:

1) Document the API
2) Verified ran xfstest against the build
3) Make struct fsverity_descriptor private
4) Reviewed (and documented) error codes
5) Improved validation of input parameters, and return error if any
   reserved field is not zero.

I left struct fsverity_hash_alg in the public API, because it adds
useful information to the user, in particular providing the digest
size, and allows the caller to walk the list to obtain the supported
algorithms. The alternative is to introduce a
libverity_get_digest_size() call.

I still need to add some self-tests to the build and deal with the
soname stuff.

Next up is rpm support.

Cheers,
Jes
