SHVC version 0.3.0 Added - Support for extracting unsigned SHV integer to the signed one and vice versa. - Support for `getLog` method in RPCHistory. Changed * `long long` and `unsigned long long` are replaced with `intmax_t` and `uintmax_t` respectively in the `struct cpitem` and `struct cpdecimal` * History handlers and `rpchandler_records` and `rpchandler_files` are merged into a signle handler `rpchandler_history`. Fixed * `cpdatetime` now correctly fills in `offutc` field. * Chainpack unpack of more than 32 bit signed negative integers * Possible memory corruption when using `rpchandler_ls_result_vfmt` * Possible deadlock in the broker when pipes are used
