prevent silent errors in daemon mode (#10007)
* prevent silent errors in daemon mode * change author in Cargo.toml, add preamble to pipe.rs * set the uid and gid on daemon process, fix permission errors when writing to pid file * call setup_logger before daemonize to prevent crashing when attempting to create logfile * map_err for calls to splice and ioctl, fix spaces in Cargo.toml * split out daemonize to own repo * removed util/daemonize * renamed dep to parity-daemonize * fix(parity-clib): enable `logger` * bump parity-daemonize * remove obsolete comment Co-Authored-By: seunlanlege <seunlanlege@gmail.com> * fix(grumbles): docs and log in ParityParams * Add FIXME comment regarding @tomaka grumbles * Unify logger with the C-API in ParityParams (less type-safety with more from_raw() conversions) * Add better documentation in the `parity.h` * Apply suggestions from code review Co-Authored-By: seunlanlege <seunlanlege@gmail.com> * docs(parity lib): add link to logging issue * fix(parity-clib): JNI enable `logger` * fix(parity-clib): update `Java example` * Update example to the API changes * Remove needless printouts which can be controlled via logger instead
