`length` was inheriting `size_t` type of the `String::length()`, while
everywhere else in the Inspector we expect fixed 32-bit field. On the
architectures where `sizeof(size_t) != sizeof(u32)` this broke the
Inspector communication completely.
Same as Vector, ByteBuffer now also signals allocation failure by
returning an ENOMEM Error instead of a bool, allowing us to use the
TRY() and MUST() patterns.
This service daemon will act as an intermediary between the Inspector
program and the inspectable programs it wants to inspect.
Programs can make themselves available for inspection by connecting
to /tmp/portal/inspectables using the Core::EventLoop RPC protocol.
