Remove authlinkedin instead

Squashed commits:
[090679e6b] authsources must be an array
[1778d0c21] only set the AuthSource if it also exists, but always remove the config
variable.
[c09669e32] add the possibility to specify one AuthSource to be shown and the rest
are used via multiauth:MultiAuth

Break with MS AD

This new feature allows the users to have a checkbox in the login form
which works in the same way than "Remember my username" but for the
organization selected in the dropdown

SHA-1 is still supported but needs to be configured explicitly if you need it.

- Attributes which can be get from LinkedIn are now configurable
- By default these attributes are requested: id,first-name,last-name,headline,summary,specialties,picture-url,email-address
- Added email-address attribute into the default set
- Fixed link to the documentation

rather than the discontinued OAuth WRAP. Attributes are now retrieved
from the Microsoft Graph API rather than the Messenger API.

(being respectful with occurences that might change the behaviour, i.e. default database prefixes)

This reverts commit 09c5a23f.

SHA-1 is still supported but needs to be configured explicitly if you need it.

Update the documentation for the sqlauth module, discouraging plain text passwords and adding the appropriate security considerations.

Modification to permit the automatic metadata creation of an SP to produce a friendlyName for RequestedAttributes.
The current code works as follows. If authsources.php contains the following configuration:

'attributes' => array(
  'eppn' => 'urn:oid:1.3.6.1.4.1.5923.1.1.1.6',
  'mail' => 'urn:oid:0.9.2342.19200300.100.1.3',
  'o' => 'urn:oid:2.5.4.10',
  'cn' => 'urn:oid:2.5.4.3',
  'givenName' => 'urn:oid:2.5.4.42',
),

the metadata generator will produce the XML Metadata as follows:

  <md:RequestedAttribute FriendlyName="eppn" Name="urn:oid:1.3.6.1.4.1.5923.1.1.1.6" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" />
  <md:RequestedAttribute FriendlyName="mail" Name="urn:oid:0.9.2342.19200300.100.1.3" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" />
  <md:RequestedAttribute FriendlyName="o" Name="urn:oid:2.5.4.10" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" />
  <md:RequestedAttribute FriendlyName="cn" Name="urn:oid:2.5.4.3" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" />
  <md:RequestedAttribute FriendlyName="givenName" Name="urn:oid:2.5.4.42" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" />

Properly document the signature.algorithm option. Also add configuration examples showing how to start using SHA-256, and warning about SHA-1 being disallowed starting in 2014.
