75139445c2 krb5_wrap: add krb5_free_enctypes()
MIT Kerberos implements krb5_free_enctypes(), Heimdal is missing it and
offers krb5_xfree() instead.
This introduces a wrapper krb5_free_enctypes() around krb5_xfree() for
Heimdal.

94fcbec8af CVE-2023-34968: mdscli: return share relative paths
The next commit will change the Samba Spotlight server to return absolute paths
that start with the sharename as "/SHARENAME/..." followed by the share path
relative appended.

So given a share

  [spotlight]
    path = /foo/bar
    spotlight = yes

and a file inside this share with a full path of

  /foo/bar/dir/file

previously a search that matched this file would returns the absolute
server-side pato of the file, ie

  /foo/bar/dir/file

This will be change to

  /spotlight/dir/file

As currently the mdscli library and hence the mdsearch tool print out these
paths returned from the server, we have to change the output to accomodate these
fake paths. The only way to do this sensibly is by makeing the paths relative to
the containing share, so just

  dir/file

in the example above.

The client learns about the share root path prefix – real server-side of fake in
the future – in an initial handshake in the "share_path" out argument of the
mdssvc_open() RPC call, so the client can use this path to convert the absolute
path to relative.

There is however an additional twist: the macOS Spotlight server prefixes this
absolute path with another prefix, typically "/System/Volumes/Data", so in the
example above the full path for the same search would be

  /System/Volumes/Data/foo/bar/dir/file

So macOS does return the full server-side path too, just prefixed with an
additional path. This path prefixed can be queried by the client in the
mdssvc_cmd() RPC call with an Spotlight command of "fetchPropertiesForContext:"
and the path is returned in a dictionary with key "kMDSStorePathScopes". Samba
just returns "/" for this.

Currently the mdscli library doesn't issue this Spotlight RPC
request (fetchPropertiesForContext), so this is added in this commit. In the
end, all search result paths are stripped of the combined prefix

  kMDSStorePathScopes + share_path (from mdssvc_open).

eg

  kMDSStorePathScopes = /System/Volumes/Data
  share_path = /foo/bar
  search result = /System/Volumes/Data/foo/bar/dir/file
  relative path returned by mdscli = dir/file

Makes sense? :)
