This commit enhances the radio URL parsing logic to detect and fail
when unused parameters are provided in the URL. This prevents typos
or unsupported parameters from being silently ignored.
The following changes were made:
- Updated ot::Url::Url to track parameter usage by appending a
trailing '&' delimiter in Init() and replacing it with '\0'
in GetValue() when a parameter is matched. This marks the
parameter as used and removes any limit on the number of
trackable parameters.
- Added a Validate() method to ot::Url::Url to verify that all
parameters in the query string were accessed.
- Refactored ot::Posix::Radio to share a single RadioUrl instance
with SpinelManager, ensuring all components track usage on the
same URL object.
- Integrated Validate() calls in otSysInit() and platformTrelInit()
to perform validation after all platform components have been
initialized.
- Updated Radio::ProcessMaxPowerTable to use a local copy of the
parameter string to avoid premature modification of the URL buffer.
- Adjusted RadioUrl and unit tests to provide sufficient buffer
space for the additional tracking delimiter.
- Added new unit tests in tests/unit/test_url.cpp to verify the
usage tracking and validation logic.
This commit updates unit test modules to be defined under the `ot`
namespace. This aligns all the unit tests to follow the same
model, eliminating the need to use `ot::` prefix in unit test
code.
This commit adds methods to parse parameter values directly from the
url, moves the url unit test to the test/unit, and updates the url
processing methods in posix platform.
