Add mgmt-tester test for hci devcoredump. This test triggers the
devcoredump with a test data and verifies the generated devcoredump
file for the test data and correct devcoredump header fields.
Signed-off-by: Manish Mandlik <mmandlik@google.com>
---
Changes in v3:
- Fix compiler warning for signed comparision in test_hci_devcd()
Changes in v2:
- Rename function names to *_devcd
