This commit updates `VerifyOrQuit()` and `SuccessOrQuit()` macros to
include the failed condition in the error message that is printed on
a failure (in addition to function name and line number where the
error happened). This commit also changes the second parameter
(`aMessage`) to in these macros to be optional.
This commit also updates unit tests to remove the second `aMessage`
string in cases where the failure can be inferred from the condition
itself.
This commit adds a new core header files `common/error.hpp` which
defines `ot::Error` (mirroring `otError`) and `kError{Name}` constants
(mirroring the public `OT_ERROR_{NAME}` definitions). The new (C++
style) definitions are used by core modules. This commit also moves
`otThreadErrorToString()` (from `logging.hpp` to `error.hpp`) and
renames it to `ErrorToString()` which is used as the internal (to
core) function to covert an `Error` to a string.
This commit adds new a type `Neighbor::AddressMactehr` which is used
to filter and find a neighbor (child/router) with a given MAC address
matching a given `Neighbor::StateFilter`. This new type helps simplify
related code in `ChildTable`/`RouterTbale`.
This commit updates `ChildTable` class. It mainly adds support for
using range-based `for` loops to iterate over all child entries
(matching a given state filter). It also simplifies the `Iterator`
implementation (removing the now unused behavior to start the
iteration from a specific child in the table). The unit test
`test_child_table` is also updated to add tests for the newly added
behavior.
This commit introduces a new class `ChildTable` as part of OpenThread
core. This class provides methods for iterating through the child
table and searching for a specific child (based on short/extended
address and/or child state). This commit also adds a unit test for the
newly added `ChildTable class.
