2019-07-04libcamera: ipa_module: elfLoadSymbol find symbol regardless of sizePaul Elder
Make elfLoadSymbol more generic by making the symbol size an output rather than an input. Also move the memcpy out of elfLoadSymbol. If the size of struct IPAModuleInfo changes between versions, we still want to be able to load it and perhaps do conversions for backwards compatibility. In this case the size should not be a restriction when searching for the symbol.

2019-07-02libcamera: controls: Extend ControlList to access controls by IDLaurent Pinchart
The ControlList class implements a map from control specifier to control ID. To avoid constant lookups of ControlInfo when using the class in the libcamera core or in pipeline handlers, the map uses ControlInfo pointers instead of ControlId values. This is however not very convenient for applications or pipeline handlers, as they would be forced to first look up the ControlInfo pointers for the controls they want to access. Facilitate ease of use of ControlLists by implementing an internal lookup of the ControlInfo from the controls provided by the Camera.
