BUG8446: Adds Shibboleth authentication

 - Use the shibbolethAuthentication syspref to enable Shibboleth authentication
 - Configure the shibbolethLoginAttribute to specify which shibboleth user
   attribute matches the koha login
 - Make sure the OPACBaseURL is correctly set

BUG8446, Follow-up: Adds Shibboleth authentication

 - Fix logout bug: shibboleth logout now occurs only when
   the session is a shibboleth one.
 - Do some refactoring: getting shibboleth username is now
   done in C4::Auth_with_Shibboleth.pm (get_login_shib function)

BUG8446, Follow-up: Adds Shibboleth authentication

 - Adds redirect to opac after logout

BUG8446, Follow-up: Adds Shibboleth authentication

 - Shibboleth is not compatible with basic http authentication
   in C4/Auth.pm. This patch fixes that.

BUG8446, Follow-up: Adds Shibboleth authentication

 - Use ENV{'SERVER_NAME'} instead of syspref OpacBaseURL in order to work with
   multiple vhosts.

BUG8446, Follow-up: Adds Shibboleth authentication

 - Adds missing protocol for $ENV{'SERVER_NAME'}

Tested with the feide idp.
- LDAP login and logout are working
- local login/logout are still working
- CAS login/logout are still working

BUG8446, Follow up: Adds Shibboleth authentication

- Use syspref OpacBaseURL instead of ENV{'SERVER_NAME'} as this wont
  work if koha is behind a reverse proxy.
  - To use multiple vhosts, set OpacBaseURL per vhost explicitly with
    'SetEnv OpacBaseURL Value' as per Bug 10325

BUG8446, Follow up: Adds Shibboleth authentication

- Ensure user is returned to requested page after authentication
  - Added querystring to the target path in shibboleth URL so
    that when a user is authenticated he/she is returned to the
    correct page they requested before authentication.
    Example where this is important: When a user clicks a direct
    biblio link of the form - /opac-detail.pl?biblionumber=12345

BUG8446, Follow up: Remove unused imports from scripts

- Remove import of deprecated C4::Utils module from shibboleth
  authentication module: Auth_with_shibboleth.pm

BUG8446, Follow up: Improve local login fallback

- Local fallback was not very well implemented, this patch adds
  better handling for such cases allowing clearer failure messages
- This patch also adds the ability to use single sign on via the
  top bar menu in the bootstrap theme.

BUG8446, Follow up: Adds perldoc documentation

- Add some documentation to the Auth_with_Shibboleth module
  including some guidance as to configuration.

BUG8446, Follow up: Correct filenames to match guidlines

- Moved Auth_with_Shibboleth.pm to Auth_with_shibboleth.pm to match
  other files present on the system.

BUG8446, Follow up: Correct paths after file rename

BUG8446, Follow up: Implemented single sign out

- This follow up rebases the code against 3.16+ which managed to break
  some of the original logic.
- As a side effect of the rebasing, we've also implemented the single
  sign out element. Upon logout, koha will request that the shibboleth
  session is destroyed, and then clear the local koha session upon
  return to koha.  Due to the nature of shibboleth however, you will
  only truly be signed out of the IdP if they properly support Single
  Sign Out (which many do not). As a consequence, although you may
  appear to be logged out in koha, you might find that upon clicking
  'login' the IdP does NOT request your login details again, but instead
  logs you silently back into your koha session. This is NOT a koha bug,
  but a shibboleth implementation issue that is well known.

BUG8446, Follow up: Fixed bootstrap login via modal

- The bootstrap theme enable login from any opac page via modal. To
  enable this with shibboleth we had to make some template parameters
  globally accessible when shibboleth is enabled.

BUG8446, Follow up: Add template rules for Shibboleth and CAS

- Add template rules so that CAS and Shibboleth can coexist.

BUG8446, Follow up: Added default config to config file

BUG8446, Follow up: Embellished perldoc documentation

- Updated perldoc to correct detail about configuring shibboleth
  authentication.
- Updated perldoc to include subroutines and their respective functions.

BUG8446, Follow up: Enable configuration of match field

- Added clearer, more flexible, configuration of shibboleth attribute to
  koha borrower field matching for authentication
- Correcting of documentation to make it more clear to the current
  implementation
- Minor refactoring of code to reduce some code duplication

BUG8446, Follow up: Refactor to clean up bad practice

- A number of issues were highlighted whilst writing sensible unit tests
  for this module.
  - Removed unnessesary call to context->new();
  - Global variables are BAD!
  - Croaking is a wimps way out, we should handle errors early and
    properly.

Bug 12927: Problems with item information tab on acq order from staged page

This patch fixes a regression introduced (by me)
on Bug 12673.

I adds the code needed to display properly all fields

To test:
1) Check that 'AcqCreateItem' syspref is set to 'placing an order'
2) Satage a file with some items
3) Go to a Vendor, create a basket, clic add from staged file, select your file
4) On 'Item information' tab fields are displayed wrong

5) Apply the patch

6) Reload, display must now be fixed

Bug 12646: Display all invoices on the same page

Only first 20 invoices were displayed on the page. Without pagination, DT
did not allow to show others.
This page explicitely removes the pagination option in order to display
all invoices on the page.

Test plan:
1/ Create 21+ invoices
2/ Go on acqui/invoices
3/ Verify all invoices are displayed.
