SSTATE_MIRRORS/SOURCE_MIRROR_URL: add instructions for mirror authentication

Browse Source 
[ YOCTO #15218 ]

There are different ways of configuring the build host when
authentication to a mirror (SSTATE_MIRRORS or SOURCE_MIRROR_URL) is
required.

Document these methods, and begin with the preferred approach which is
to edit ~/.netrc appropriately. When that is not possible, specifying
the credentials from the URL is also possible, so document it as well.

You can specify only a single URL in :term:`SOURCE_MIRROR_URL`.
.. note::
If the mirror is protected behind a username and password, the
:term:`build host` needs to be configured so the :term:`build system
<OpenEmbedded Build System>` is able to fetch from the mirror.
The recommended way to do that is by setting the following parameters
in ``$HOME/.netrc`` (``$HOME`` being the :term:`build host` home
directory)::
machine example.com
login <user>
password <password>
This file requires permissions set to ``400`` or ``600`` to prevent
other users from reading the file::
chmod 600 "$HOME/.netrc"
Another method to configure the username and password is from the URL
in :term:`SOURCE_MIRROR_URL` directly, with the ``user`` and ``pswd``
parameters::
SOURCE_MIRROR_URL = "http://example.com/my_source_mirror;user=<user>;pswd=<password>"
:term:`SPDX_ARCHIVE_PACKAGED`
This option allows to add to :term:`SPDX` output compressed archives
of the files in the generated target packages.
