Merge lp://staging/~phablet-team/ubuntu-settings-components/printer-components into lp://staging/ubuntu-settings-components

internalizes cph stuff

inch closer to settings duplex

latest changes

makes string stuff in pkhelper saner

enables you to set the duplex of a printer

fix path errors

adds metaobj to cupsfacade system, other various fixes

allows read/write of pageSize

adds pagesize read/write

adds colormodels stuff

merges andrews printerjob work, as well as solving any conflicts

corrects case where having colormodels gave you a dud as well, and fixes some warnings

implements setData for ColorModel

implements setData for ColorModel

fixes colormodel implementation for printers with models

* Add QTimer to poll availablePrinters for changes
* Improve update in PrinterModel so that it uses insert/move/remove instead of clear
* Add tests to ensure that insert/move/remove of printers works

* Create startTimer method in PrinterModel

* Expose colorModelType to QML
* Fix utils detection of colorModelType
* Change startTimer to not be a pointer
* Use new helpers in makeDest

adds implementation of a proxyfilter for allPrinters, sorted by default

migrates to allPrinters and marks the default

merges andrews latest and solves conflicts

removes displayrole arg in test as it is not needed

* adds count and countChanged on the printer filter proxy by redirect of signal
* tests count and countChanged on PrinterFilter in tst_printerfilter

* Add getter method to PrinterModel
* Fix issue in update when removing multiple rows (also added regression test)
* Add refresh command to PrinterInfo
* Add ability for setting defaults to emit signals, so when a default is set it remains set on the QML side

* Add a Printers::allPrintersWithPdf option which includes a fake pdf at the bottom
* Add a PrinterInfoAllImpl which combines PrinterInfoPdfImpl and PrinterInfoImpl for listing
* Add a PrinterInfoPdfImpl which implements a fake pdf printer (just a name in the list)
* Add isPdf role to PrinterModel
* Add filterOnPdf to PrinterModel to allow for only showing pdf printers
* Force pdf printers to bottom of the PrinterModel
* Inject a fake ColorModel in PrinterPrivate::loadColorModel for pdf printers
* Change PrinterJob::setPrinterName to use PrinterInfoAllImpl for retreiving the PrinterInfo
* Improve the UI names for the Duplex modes
* Improve detection of color models so that "black" is a greyscale type
* In the example disable duplex mode when there is only None
* Fix colorModelType not emitting when it may have changed, causing QML to get out of sync

* Implements read/write of select Quality ppd settings
* Updates PrinterJob to use the correct quality setting
* Fixes broken ColorModel system, now reflects most ppds, and leaves the ppd implementation details in the ppd (colorspace, organization, etc)

* packaging: suggest cups, depend on libcups2-dev
* adds cups bindings for printer/job management

* Rewrites Printer, PrinterJob, PrinterModel to all use a new backend.
* Adds new backend that bridges PDF and Cups implementations.
* Drops PIMPL idiom since we're not going to export C++ headers anyway.
* Drops most bridge patterns in classes that are now implementation details (QPrinterInfo, CupsFacade).
* Tries to deal with some RAII issues.

syncs with trunk

Jonas G. Drange 2017-01-23 deletes old, unused mocks

adds printer state

* Add support for translations in the printer components

* Add Collate and Reverse options to PrinterJob

* Add isTwoSided read-only property to PrinterJob which allows the QML to know if the selected duplexMode is actually going to print double sided

resolves conflicts

* Skip null printers for now as they result in errors due to missing ppd definitions and segfaults when trying to print

  * allows creation of printers in example qml, and by extension the API
  * create printers by either providing a PPD file, or select a PPD from the database
  * adds a DriverModel that holds printer drivers, which can be filtered
  * adds testing of DriverModel

* Always fit-to-page for now as printing app doesn't know about page sizes or scaling yet

* Add cancel method to Printers

* Add JobModel which lists the jobs for a certain printer
* Add JobRole to PrinterModel to access jobs
* Add JobState enum to track enums from cups
* Add example Queue which lists jobs for a printer with their name, id, status and allows you to cancel the job by clicking

* Deprecate QTimer based update()
* Replace with cups subscription based update()
* Fixes tests.

* Add updateFrom to Printer and PrinterJob
* Call updateFrom in PrinterModel and JobModel when printers are the same
* Emit dataChanged signal in models when updateFrom returns a change
* Add deepCompare to Printer and PrinterJob

* Link notifications to JobModel - removing polling
* Fix compiler errors that appeared from the previous branch
* Fix logic change in last branch that was wrong way around

* Resolve console warnings - add TODOs in methods that should be implemented where I've put a fake return value for now
* Set a default for switches that compiler thinks it can reach the end of the control without
* Add return values for methods that are not implemented yet
* Add Q_UNUSED for parameters that aren't used

* Expose many more properties of PrinterJob to the JobModel
* Load PrinterJob properties from the ipp job attributes when loading for the JobModel

merges ~jonas-drange/ubuntu-settings-components/asyncness/

frees all the jobs which works fine

* adds PrinterSignalHandler that is responsible for handling (some) printer signals.
* uses PrinterSignalHandler in PrinterModel so that i only will update printers a minimum number of times
