Inspired by the poor error message here: https://github.com/scottlamb/moonfire-nvr/issues/107#issuecomment-777587727 * print the friendlier Display version of the error rather than Debug. Eg, "EROFS: Read-only filesystem" rather than "Sys(EROFS)". Do this everywhere: on command exit, on syncer retries, and on stream retries. * print the most immediate problem and additional lines for each cause. * print the backtrace or an advertisement for RUST_BACKTRACE=1 if it's unavailable. * also mention RUST_BACKTRACE=1 in the troubleshooting guide. * add context in various places, including pathnames. There are surely many places more it'd be helpful, but this is a start. * allow subcommands to return failure without an Error. In particular, "moonfire-nvr check" does its own error printing because it wants to print all the errors it finds. Printing "see earlier errors" with a meaningless stack trace seems like it'd just confuse. But I also want to get rid of the misleading "Success" at the end and 0 return to the OS.
