When cloning the ot-br-posix repository to run the Docker-in-Docker
integration tests, the clone was shallow and did not recursively
check out nested submodules (such as cJSON and cpp-httplib). This led
to build failures inside the Docker build container since libcjson
is not pre-installed on the base build image.
This commit resolves the issue by:
1. Appending the `--recurse-submodules` flag to the git-tool clone
calls in `otbr-posix-dind.yml` and `script/test`.
2. Updating `script/git-tool`'s destination directory parsing to
robustly handle multi-line output from recursive submodule
checkouts. The new pattern extracts the path exclusively from
the first line using `sed` to prevent SIGPIPE or parsing errors.
The length of diag output messages is limited by the diag buffer size.
Developers have to change the diag buffer size to allow diag module to
output long messages. If diag output messages become longer and
longer, developers have to keep changing the diag buffer size.
This commit adds an output callback to diag module to output diag
messages. Then the length of diag output messages won't be limited by
the diag buffer size.
