Add an Azure storage backend that uses the Microsoft SDK

S3Proxy currently uses Apache jclouds for its Azure Blob integration. This uses the native REST API and has some advantages in terms of similar configuration and logging. However the [Microsoft...

I deployed a SNAPSHOT and saw that there are only MD5 and SHA1 hashes: ``` s3proxy-2.1.0-20230816.115951-3.jar Wed Aug 16 12:02:33 UTC 2023 2265577 s3proxy-2.1.0-20230816.115951-3.jar.md5 Wed Aug 16 12:02:34 UTC 2023...

Instead of large object mocking, it might be better for the filesystem and transient storage backends to use sparse objects, collapsing the zero-byte ranges into a range. This should be...

Reduce local scope where possible, handle realloc failure, and unify malloc error handling with realloc(NULL).
