Fix memory leak, add volatile, reduce duplication

- config.c: free partial strdup on configAppend failure
- common.c: consolidate loadTrustStore error paths with goto
- server_lds.c, server_register.c: make running volatile, remove
  non-async-signal-safe call from signal handler
- server_register.c: extract LdsClientParams + makeLdsClientConfig
  to deduplicate the register/deregister client config setup
