Switch to using libarchive from libtar for cpack and cmake -E tar

This allows for a built in bzip and zip capability, so external tools
will not be needed for these packagers.  The cmake -E tar xf should be
able to handle all compression types now as well.

+.Sh DESCRIPTION
+These functions create and manipulate data objects that
+represent entries within an archive.
+You can think of a
+.Tn struct archive_entry
+as a heavy-duty version of
+.Tn struct stat :
+it includes everything from
+.Tn struct stat
+plus associated pathname, textual group and user names, etc.
+These objects are used by
+.Xr libarchive 3
+to represent the metadata associated with a particular
+entry in an archive.
+.Ss Create and Destroy
+There are functions to allocate, destroy, clear, and copy
+.Va archive_entry
+objects:
+.Bl -tag -compact -width indent
+.It Fn archive_entry_clear
+Erases the object, resetting all internal fields to the
+same state as a newly-created object.
+This is provided to allow you to quickly recycle objects
+without thrashing the heap.
+.It Fn archive_entry_clone
+A deep copy operation; all text fields are duplicated.
+.It Fn archive_entry_free
+Releases the
+.Tn struct archive_entry
+object.
+.It Fn archive_entry_new
+Allocate and return a blank
+.Tn struct archive_entry
+object.
+.El
+.Ss Set and Get Functions
+Most of the functions here set or read entries in an object.
+Such functions have one of the following forms:
+.Bl -tag -compact -width indent
+.It Fn archive_entry_set_XXXX
+Stores the provided data in the object.
+In particular, for strings, the pointer is stored,
+not the referenced string.
+.It Fn archive_entry_copy_XXXX
+As above, except that the referenced data is copied
+into the object.
+.It Fn archive_entry_XXXX
+Returns the specified data.
+In the case of strings, a const-qualified pointer to
+the string is returned.
+.El
+String data can be set or accessed as wide character strings
+or normal
+.Va char
+strings.
+The functions that use wide character strings are suffixed with
+.Cm _w .
+Note that these are different representations of the same data:
+For example, if you store a narrow string and read the corresponding
+wide string, the object will transparently convert formats
+using the current locale.
+Similarly, if you store a wide string and then store a
+narrow string for the same data, the previously-set wide string will
+be discarded in favor of the new data.
+.Pp
+There are a few set/get functions that merit additional description:
+.Bl -tag -compact -width indent
+.It Fn archive_entry_set_link
+This function sets the symlink field if it is already set.
+Otherwise, it sets the hardlink field.
+.El
+.Ss File Flags
+File flags are transparently converted between a bitmap
+representation and a textual format.
+For example, if you set the bitmap and ask for text, the library
+will build a canonical text format.
+However, if you set a text format and request a text format,
+you will get back the same text, even if it is ill-formed.
+If you need to canonicalize a textual flags string, you should first set the
+text form, then request the bitmap form, then use that to set the bitmap form.
+Setting the bitmap format will clear the internal text representation
+and force it to be reconstructed when you next request the text form.
+.Pp
+The bitmap format consists of two integers, one containing bits
+that should be set, the other specifying bits that should be
+cleared.
+Bits not mentioned in either bitmap will be ignored.
+Usually, the bitmap of bits to be cleared will be set to zero.
+In unusual circumstances, you can force a fully-specified set
+of file flags by setting the bitmap of flags to clear to the complement
+of the bitmap of flags to set.
+(This differs from
+.Xr fflagstostr 3 ,
+which only includes names for set bits.)
+Converting a bitmap to a textual string is a platform-specific
+operation; bits that are not meaningful on the current platform
+will be ignored.
+.Pp
+The canonical text format is a comma-separated list of flag names.
+The
+.Fn archive_entry_copy_fflags_text
+and
+.Fn archive_entry_copy_fflags_text_w
+functions parse the provided text and sets the internal bitmap values.
+This is a platform-specific operation; names that are not meaningful
+on the current platform will be ignored.
+The function returns a pointer to the start of the first name that was not
+recognized, or NULL if every name was recognized.
+Note that every name--including names that follow an unrecognized name--will
+be evaluated, and the bitmaps will be set to reflect every name that is
+recognized.
+(In particular, this differs from
+.Xr strtofflags 3 ,
+which stops parsing at the first unrecognized name.)
+.Ss ACL Handling
+XXX This needs serious help.
+XXX
+.Pp
+An
+.Dq Access Control List
+(ACL) is a list of permissions that grant access to particular users or
+groups beyond what would normally be provided by standard POSIX mode bits.
+The ACL handling here addresses some deficiencies in the POSIX.1e draft 17 ACL
+specification.
+In particular, POSIX.1e draft 17 specifies several different formats, but
+none of those formats include both textual user/group names and numeric
+UIDs/GIDs.
+.Pp
