Combine auth path and keygen root functions
...
This greatly reduces the memory comsumption of the auth path
computation, since it now also uses treehash. It prevents
duplicate code by re-using the treehash function.
A downside is that it does also pick out the authentication path
during key generation (while it is not used), but this cost is
negligible.

Add test to check deterministic signatures
...
Wrote this to find what turned out to be an external error when
using the interfacing programs, but felt like it might as well be added.
Under the same key and message, the signature is expected to be identical.
However, as the index changes, this case will not happen in real use.

Fix integer underflow when writing updated sk
...
This caused secret key files to become close to MAXINT bytes, as
the unsigned int that is the private key size would be subtracted
from MAXINT when its negative was used as offset.

Merge branch 'master' into defined-parameters
...
The defined-parameters branch should be the new leading branch,
as it supersedes master. This merge is performed using --strategy ours
as there are numerous conflicting changes regarding the different ways
in which SHA3 was added. The master branch is considered to not contain
anything of value that is not contained in the defined-parameters branch.
Prior to merging, the defined-parameters branch was rebased to prevent
the cherry-picked commits from showing up twice.
