Allow optional issuing of ListObjectsV2 (#1583)
This allows use of s3fs on object stores that do not implement
the V1 API.  Fixes #1573.

Allow configuring the multipart threshold (#1562)
Also change default which improves write performance for files >= 25
MB and <= 5 GB, particularly over lossy networks.

Do not periodically flush with nomultipartupload (#1559)
s3fs periodically flushes data to S3 and hole-punches the written
data, marking it as clean.  Without multipart copy, s3fs would write
the now-zeroed data along with any new data.  s3fs should not attempt
to periodically flush dirty data at all without multipart copy
support.  Fixes #1542.

Return more specific errno when available (#1520)
Previously s3fs threw away some function return values and returned
EIO instead.  This was due to not trusting the mix of -1 and errno
return codes.  Correct the obviously incorrect ones via visual
inspection.  Stronger typing may find more occurrences.  Fixes #1519.

f2f930300a Implement AWS IMDSv2 support
AWS IMDSv2 is a session oriented method for retrieving instance metadata,
including IAM credentials, in Amazon EC2.  It is enabled by default in
non-enforcing mode in AWS (meaning it retains backwards compatibility with
existing IMDSv1 clients), but can be switched to enforcing mode, in which
clients are required to return API tokens with requests.

With this change, we implement support for IMDSv2 and enable it by default when
IAM roles are our source for authentication credentials.  In the event that
s3fs is running in cloud environment offering an IMDSv1-compatible API, we
support graceful fallback to that mode.  It can also be selected explicitly via
the imdsv1only mount option.

More details on IMDSv2 are available at
https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-data-retrieval.html
and

Flush dirty data after a writing a number of bytes (#1448)
This allows s3fs to write large files without consuming a large amount
of temporary local storage but can slow uploads due to server-side
copies.  References #617.  Fixed #1056.  Fixes #1257.

return 0 after parsing "use_session_token" arg (#1388)
return 0 after parsing "use_session_token" arg

I hope this might fix #651.

There's clearly an open bug in #651 confirmed by several users related to the parsing of the `-o use_session_token`. Looking at the source, I noticed that there was a return value everywhere except here, so I suspect this may be responsible.
