GENDLT-15, Avoid buffer overrun with snprintf().

Check return value of dlt_user_log_write_start(_id) correctly.
Reduce the number of applications if allocation fails.
Make dlt_user_log_write_start inline
Improve error checking in dlt_user_log_write_start_id
Use databuffersize to avoid reallocations
