[libcamera-devel] [PATCH v2 5/8] cam: options: Store options in a list instead of a vector

When option are added to the parser, they are stored in the
OptionsParser::options_ vector, and a pointer to the option referencing
the vector entry is indexed in the OptionsParser::optionsMap_ map. When
the next option is added the vector may be resized, which invalidates
the pointers stored in the map.

Fix this by storing the options in an std::list<> instead of
std::vector<>.
