Alejandro Hernandez Samaniego 0f84d24df8 bitbake: bitbake: Add Azure Storage fetcher implementation
Allows bitbake to fetch from an Azure Storage account.

        The fetcher submodule is compatible with the az:// URI protocol, its
        functionality is based on bitbakes wget fetcher, superior in performance
        to using a propietary tool like azcopy which can handle cloud storage
        account operations with more functionality (that we dont need in a fetcher)
	but less compatibility.

        A sample URI uses can be defined in the following way:
	SRC_URI = "az://<azure-storage-account>.blob.core.windows.net/<container>/foo.tar.xz"

        This fetcher can easily be used with PREMIRRORS and SSTATE_MIRRORS, e.g.:

        SSTATE_MIRRORS = "file://.* az://<azure-storage-account>.blob.core.windows.net/sstate-cache/PATH;downloadfilename=PATH \n"

        PREMIRRORS_prepend = "\
            git://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
            ftp://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
            http://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
            https://.*/.* az://<azure-storage-account>.blob.core.windows.net/downloads/ \n \
        "

        Can also be used with non-public access Azure Storage accounts/containers via a
        Shared Access Signature by declaring the AZ_SAS variable which will be
        automatically used by the fetcher:

        AZ_SAS="?sv=2000-01-01&ss=...&sig=somesignature"

Bitbake
=======

BitBake is a generic task execution engine that allows shell and Python tasks to be run
efficiently and in parallel while working within complex inter-task dependency constraints.
One of BitBake's main users, OpenEmbedded, takes this core and builds embedded Linux software
stacks using a task-oriented approach.

For information about Bitbake, see the OpenEmbedded website:
    http://www.openembedded.org/

Bitbake plain documentation can be found under the doc directory or its integrated
html version at the Yocto Project website:
    http://yoctoproject.org/documentation

Please refer to
http://www.openembedded.org/wiki/How_to_submit_a_patch_to_OpenEmbedded
for guidelines on how to submit patches, just note that the latter documentation is intended
for OpenEmbedded (and its core) not bitbake patches (bitbake-devel@lists.openembedded.org)
but in general main guidelines apply. Once the commit(s) have been created, the way to send
the patch is through git-send-email. For example, to send the last commit (HEAD) on current
branch, type:

    git send-email -M -1 --to bitbake-devel@lists.openembedded.org
