A new CRCHasher class wraps crc functions to mimic the hashlib
hasher interface.
For crc32, use the zlib implementation.
For crc32c, use ISA-L if we can find it; on py38+ this includes the
ISA-L bundled in pyeclib's binary wheels.
If ISA-L is not available, check for kernel crypto API support for crc32c;
use it if available. Otherwise, raise a NotImplementedError.
No callers yet, but these will be used by s3api in a later patch.

This will prevent client timeouts during large object copies, similar to existing support in
bulk operations and SLO manifest writes. The operator can set the frequency using the
yield_frequency inside conf file.
To use heartbeat, simply add "heartbeat=on" query parameter, which will:
- Returns a 202 Accepted response
- Sends periodic 1 byte whitespace heartbeat every yield_frequency
- Returns final status and headers
- Supports both plain text and JSON

Tempauth fernet tokens use a secret shared among all proxies to encrypt
user group information. Because they are encrypted, clients can neither
view nor edit this information; it is an opaque bearer token similar to
the existing memcached-backed tokens (just much longer). Note that
tokens still expire after the configured token_life.
Add a new set of config options of the form
 fernet_key_<keyid> = <32 url-safe base64-encoded bytes>
Any of the configured keys will be used to attempt to decrypt tokens
starting with "ftk" and extract group information.
Another new config option
 active_fernet_key_id = <keyid>
dictates which key should be used when minting tokens. Such tokens
will start with "ftk" to distinguish them from memcached-backed tokens
(which continue to start with "tk"). If active_fernet_key_id is not
configured, memcached-backed tokens continue to be used.
Together, these allow seamless transitions from memcached-backed tokens
to fernet tokens, as well as transitions from one fernet key to another:
 1. Add a new fernet_key_<keyid> entry.
 2. Ensure all proxies have the new config with fernet_key_<keyid>.
 3. Set active_fernet_key_id = <keyid>.
 4. Ensure all proxies have the new config with the new
 active_fernet_key_id.
This is similar to the key-rotation process for the encryption feature,
except that old keys may be pruned following a token_life period.
Additionally, opportunistically compress groups before minting tokens.
Compressed tokens will begin with "zftk" but otherwise behave just like
"ftk" tokens.

Now that we no longer need to support py2, iterating over bytes always

... so that eventlet.wsgi will include Connection: close headers on
Expect: 100-continue error responses from s3api and make aws clients
less unhappy.
eventlet.wsgi likes to check for hasattr('__len__', resp) when setting
connection close on expect-100 errors, but uses 'content-length' in
headers when deciding on chunked-transfer.
When we know the length we can support either interface. Also we can
imporove s3api to return error responses with the content-length known.

Previously the SigV4Mixin would override S3Request signature checking
methods. This patch refactors the signature checking into sigv2 and
sigv4 helper classes i.e. moves towards composition rather than
inheritance.
No behavioural changes are intended with this patch.

Currently our test names are long and we pipe pytest output to a file,
so the skip reason gets truncated; setting this env var .zuul and
passing to tox.ini will allow us to see the reason why pytest is
skipping next to the test name.
Drive-by: remove passenv from s3api tests in tox.ini so they are
inherited from testenv

The swift-tox-func-s3api-tests-tempauth runs the tests in test/s3api.
The swift-tox-func-s3api-ceph-s3tests-tempauth doesn't run the tests
in test/s3api. This patch changes the names of those jobs to
disambiguate the prefix 'swift-tox-func-s3api' and avoid any
suggestion that the second job is a super-set of the first job.

The method is redundant and confusingly named. Since the
Related-Change it actually returns the aggregate value of counters,
not just the count of calls made to the increment method alone.

Both the StatsdClient and LabeledStatsdClient implemented all of the
public interface methods for an AbstractStatsdClient. Even though the
implementations are identical the interfaces themselves were made
different WRT the "last" positional arg if provided.
This change puts the identical implementations of the public interface
in the AbstractStatsdClient class with a generic interface. For
backwards compat with the existing public interface on the
legacy-StatsdClient we have to make the old signature explicit - but we
can transparently call into the common implementation.
For consistency with legacy-Statsdclient and better docstrings this
change also "fixes" the signature for the new LabeledStatsdClient public
interface methods so they explicitly state labels must always be passed
in as a kwarg to avoid confusion accidentally passing in
`sample_rate=<dict>` or `label=<float>` as a positional arg.
Drive-by: as a side-effect of consolidating the implementations there
was now only one place to extend a fix in the FakeStatedClient interface
so that tests who assert StatsdClient method calls don't have to read
like the UUT also called some *other* public StatsdClient method; which
also cleaned up some Fake helpers that deal specifically with counters.
Drive-by: fix stub return value TypeError in a _get_hashes mock that was
caught by better faking. N.B. it doesn't matter how statsd would have
handled 'metric:None|c' because it was only a test bug.

Introduce a LabeledStatsdClient API; no callers yet.
Include three config options:
 - statsd_label_mode, which specifies which label format to use
 - statsd_emit_legacy, which dictates whether to emit old-style
 metrics dotted metrics
 - statsd_user_label_<name> = <value>, which supports user defined
 labels in restricted ASCII characters
