Previously ignored sccp extensions in freepbx devices and so created 'orphans'. Now create rows for sccpline for devices that already exist as sccp extensions in devices.
Remove dbug code
Mariadb does not accept _prefixed fields by spec, and these columns may give future issues. Migrate all fields in installer to remove this prefix (without data loss) and:
Create new view sccplineconfig for chan-sccp where only accepted fields are shown
Update sccpdeviceconfig to only show accepted fields
Update extconfigs.conf to use sccplineconfig
Remove references to _ prefixed fields
Add choice of default line on add device
Partially fix buttoncount (will not work if default device is selected)
Correct database save logic for buttons - triggers should be OK but more verification needed
Fix various save issues where defaults not correctly set
Delete default buttons when deleting line to avoid orphans
Get country files with locales
WIP incompatibility between provision, its rewrite rules and the file structure
WIP - need to clean up get files from provisioner
Add device to extensions page - permits to see unassigned lines and shared lines easily
Reformat status to centred
change 'replace' in sccp class to only 'insert on duplicate key' (UPSET equivalent)
Change request in phoneGrid to left join to show all lines, even unassigned to a device
codecs were stored as a ',' separated list while chan-sccp expects a ';' separated list
Correct all existing db values when running installer
make sure that disallow is not unset in installer (set to all)
make sure that disallow is not empty
correct help text
Optimise function calls
Use array functions instead of loops
findInstalledlangs is currently called by the construct - as this is called frequently, maximise its efficiency
User no longer can select on or pro: If remapping is enabled and rules are set, then must use pro or phones will not find files
Otherwise is Off (flat directory)
Create required directory structure
Check if mapping support is enabled
Check if mapping rules are defined
Change options available based on above
Create index.cnf and sccpManagerRewrite.rules
If all codecs are unchecked, restores values to site codecs
Remove options that have no input (do not offer user empty lists)
Respect site dndFeature by hiding option if off
Move help and other defs to sccpgeneral so that have one interface across system
Correct defaults in line with chan-sccp
Standardise db object, and move sql to dbinterface to remove second dependancy
