839c4a5a48 libcamera: yaml_parser: Fix range checks for 32-bit integers 
The strtol() and strtoul() functions return long integers, which may be
larger than 32-bit integers. Add manual range checks.

9dacead615 libcamera: yaml_parser: Remove memberNames() function 
Now that YamlObject supports iteration, the memberNames() function isn't
useful anymore as it can be implemented using utils::map_keys() if
really needed. Drop it.

3a18ad1607 libcamera: yaml_parser: Add iterator API 
Allow using range-based for loops over YamlObject instances by
implementing iterators. New YamlObject::DictAdapter and
YamlObject::ListAdapter adapter classes are introduced to provide
different iterators depending on the object type.

d6d0a675bf libcamera: yaml_parser: Switch from FILE to File 
THe FILE object isn't very user-friendly as it requires manual close.
Replace it with File to provide RAII-style resource management in the
YamlParser API.

27483e971f libcamera: yaml_object: Turn Type into an enum class 
Turn the Type enum into an enum class to force qualifying 'List' and
'Dictionary' in the YamlObject namespace scope. This will help avoiding
ambiguities when adding iterator support.

fcb0ea001a libcamera: Introduce YamlParser as a helper to parse yaml files 
Introduce YamlParser as a helper to convert contents of a yaml file to
a tree based structure for easier reading, and to avoid writing parser
with raw yaml tokens. The class is based on libyaml, and only support
reading but not writing a yaml file.

The interface is inspired by Json::Value class from jsoncpp:
