ghash v0.5.1

[baloo]

Added

• add new_with_init_block (add new_with_init_block #195)

[tarcieri]

Note: we'll need to bump the polyval version requirement to v0.6.2 after it's released, since ghash now makes use of new APIs in that release

[baloo]

Grown too accustomed to the CI having my back with minimal-versions :D

[baloo]

will need to be rebased on #197 once merged

Edit: actually, git should be fine, resolve that with git patch-id and sort this out on its own

[tarcieri]

polyval v0.6.2 is released

[tarcieri]

Made some additional changes on master if you can rebase

[baloo]

rebased
