For those not already familiar with the code base it can be a challenge to understand how the libraries are laid out. This has sometimes resulted in functionality being added in the wrong place. To help avoid that in the future this commit documents the high-level dependencies for easy reference in lib/Makefile.am. It also simplifies a few things. - Switched libzpool dependency on libzfs_core to libzutil. This change makes it clear libzpool should never depend on the ioctl() functionality provided by libzfs_core. - Moved zfs_ioctl_fd() from libzutil to libzfs_core and renamed it lzc_ioctl_fd(). Normal access to the kmods should all be funneled through the libzfs_core library. The sole exception is the pool_active() which was updated to not use lzc_ioctl_fd() to remove the libzfs_core dependency. - Removed libzfs_core dependency on libzutil. - Removed the lib/libzfs/os/freebsd/libzfs_ioctl_compat.c source file which was all dead code. - Removed libzfs_core dependency from mkbusy and ctime test utilities. It was only needed for some trivial wrapper functions and that code is easy to replicate to shed the unneeded dependency.
