Add unit tests for the `net` component about cookies. The tests are generated
with a new `mach update-net-cookies` command from this repo: https://github.com/abarth/http-state.
This PR also includes two trivial bug fixes about cookie handling.
From all the tests included, the following ones are currently failing:
- cookie_http_state::test_0003
- cookie_http_state::test_0006
- cookie_http_state::test_attribute0004
- cookie_http_state::test_attribute0005
- cookie_http_state::test_attribute0007
- cookie_http_state::test_attribute0008
- cookie_http_state::test_domain0017
- cookie_http_state::test_mozilla0001
- cookie_http_state::test_mozilla0002
- cookie_http_state::test_mozilla0003
- cookie_http_state::test_mozilla0005
- cookie_http_state::test_mozilla0007
- cookie_http_state::test_mozilla0009
- cookie_http_state::test_mozilla0010
- cookie_http_state::test_mozilla0013
`test_000[36]` and `test_mozilla*` are failing because there is currently no
method to clean a `net::cookie_storage` from expired cookies.
`test_attribute000[4578]` are failing because hyper does not parse the `Secure`
attribute correctly. I will open an issue on the upstream project.
`test_domain0017` fails because the TLD .org is not on the PUB_DOMAINS list.
