libshare: use AVL tree with static data, pass all data in arguments
This makes it so we don't leak a consistent 64 bytes anymore, makes the searches simpler and faster, removes /all allocations/ from the driver (quite trivially, since they were absolutely needless), and makes libshare thread-safe (except, maybe, linux/smb, but that only does pointer-width loads/stores so it's also mostly fine, except for leaking smb_shares) Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Ahelenia Ziemiańska <nabijaczleweli@nabijaczleweli.xyz> Closes #13165
