Rename krb5 and krb5-lib to kerberos and kerberos-lib to match the existing Heimdal package names. Since it's not possible to build or install both at the same time, and Heimdal will be removed anyway, there's no benefit to using a different package name for MIT Kerberos and doing so will create friction for pkgbase users. Move a few things (e.g., headers) from kerberos to kerberos-lib. Move the KDC to a new package, kerberos-kdc, so the client utilities can be installed without the KDC. As most systems won't have the KDC running, this saves a bit of disk space for jails/containers. Remove a few instances of 'PACKAGE=' in target-specific Makefiles where we can set that in the parent's Makefile.inc instead. Revert 01c587521dd8 ("OCI: Attempt to fix "runtime" container") which is no longer required. The KDC init script is still installed in the 'rc' package for compatibility with the security/krb5 port; we should fix this at some point, possibly after Heimdal is removed.
