OK. Patch isn't applying to trunk, oddly enough

> Update WASB driver to use the latest version (5.3.0) of SDK for Microsoft 
> Azure Storage Clients. We are currently using version 4.2.0 of the SDK.
> Azure Storage Clients changes between 4.2 and 5.3:
>  * Fixed a bug where the transactional MD5 check would fail when downloading 
> a range of blob or file and the recovery action is performed on a subsection 
> of the range.
>  * Fixed leaking connections for table requests.
>  * Fixed a bug where retries happened immediately when experiencing a network 
> exception uploading data or getting the response.
>  * Fixed a bug where the response stream was not being closed on nonretryable 
> exceptions.
>  * Fixed Exists() calls on Shares and Directories to now populate metadata. 
> This was already being done for Files.
>  * Changed blob constants to support up to 256 MB on put blob for block 
> blobs. The default value for put blob threshold has also been updated to half 
> of the maximum, or 128 MB currently.
>  * Fixed a bug that prevented setting content MD5 to true when creating a new 
> file.
>  * Fixed a bug where access conditions, options, and operation context were 
> not being passed when calling openWriteExisting() on a page blob or a file.
>  * Fixed a bug where an exception was being thrown on a range get of a blob 
> or file when the options disableContentMD5Validation is set to false and 
> useTransactionalContentMD5 is set to true and there is no overall MD5.
>  * Fixed a bug where retries were happening immediately if a socket exception 
> was thrown.
>  * In CloudFileShareProperties, setShareQuota() no longer asserts in bounds. 
> This check has been moved to create() and uploadProperties() in 
> CloudFileShare.
>  * Prefix support for listing files and directories.
>  * Added support for setting public access when creating a blob container
>  * The public access setting on a blob container is now a container property 
> returned from downloadProperties.
>  * Add Message now modifies the PopReceipt, Id, NextVisibleTime, 
> InsertionTime, and ExpirationTime properties of its CloudQueueMessage 
> parameter.
>  * Populate content MD5 for range gets on Blobs and Files.
>  * Added support in Page Blob for incremental copy.
>  * Added large BlockBlob upload support. Blocks can now support sizes up to 
> 100 MB.
>  * Added a new, memory-optimized upload strategy for the upload* APIs. This 
> algorithm only applies for blocks greater than 4MB and when 
> storeBlobContentMD5 and Client-Side Encryption are disabled.
>  * getQualifiedUri() has been deprecated for Blobs. Please use 
> getSnapshotQualifiedUri() instead. This new function will return the blob 
> including the snapshot (if present) and no SAS token.
>  * getQualifiedStorageUri() has been deprecated for Blobs. Please use 
> getSnapshotQualifiedStorageUri() instead. This new function will return the 
> blob including the snapshot (if present) and no SAS token.
>  * Fixed a bug where copying from a blob that included a SAS token and a 
> snapshot ommitted the SAS token.
>  * Fixed a bug in client-side encryption for tables that was preventing the 
> Java client from decrypting entities encrypted with the .NET client, and vice 
> versa.
>  * Added support for server-side encryption.
>  * Added support for getBlobReferenceFromServer methods on CloudBlobContainer 
> to support retrieving a blob without knowing its type.
>  * Fixed a bug in the retry policies where 300 status codes were being 
> retried when they shouldn't be.
