Bug 25712: Add plugin hooks to transform patron and item barcodes

Some of our partners have unusual barcode requirements that have
required us to transform scanned barcodes using javascript. This is not
the most reliable method. It would make more sense to have Koha
transform the barcodes on the backend using a plugin. We should add
hooks to transform and generate new item and patron barcodes.

Test Plan:
1) Apply this patch
2) Download and install the Barcode Transformer plugin
  
https://github.com/bywatersolutions/koha-plugin-barcode-transformer/releases/
3) Go to the plugin configuration page, set the configuration to the example
configuration from the same page
4) In the patron search and anywhere else you can scan a patron
cardnumber, type in some cardnumbers but prefix them with A and postfix
them with A or B, e.g. A12345A, A12345B
5) Note the letters are removed by Koha!
6) Try a cardnumber like X123456Y
7) Note Koha converts it to Z13456Z
8) Try an item barcode now with the same A A|B format from step 4
9) The item barcode should have the letters removed by Koha as well!
