8e5f7cf3dc Move lvmcache data structures behind an API (making the structures private to
lvmcache.c). No functional change.

09e0f43ba0 Allow raw_read_mda_header to be called from text_label.c.
We'd like to pass in mda_header to vgname_from_mda().  In order to
do this, we need to call raw_read_mda_header() from text_label.c,
_text_read(), which gets called from the label_read() path, and
peers into the metadata and update vginfo cache.  We should check
the disable bit here, and if set, not peer into the vg metadata,
thus reducing the I/O to disk.

In the process, move vgname_from_mda() to layout.h, since the fn
only gets called from format_text code, and we need the mda_header
definition from the private layout.h.

d144d5eeb7 Add text format specific 'rlocn' ignore flag and access functions.
Adding a flag to the 'rlocn' structure in the mda header of the
text format allows us to flip a bit to ignore an area on disk that
stores the metadata via the text format specific mda_header.
This patch defines the flag and access functions to manage the flag.
Other patches will manage the ignore on a format-independent basis,
by using a flag in the metadata_area structure.

7c604e7649 Change 'filler' to 'flags' in on-disk 'raw_locn' structure.
Future patches will make use of a specific flag in the on-disk 'raw_locn'
structure to enable/disable metadata areas, and facilitate metadata
balancing.

Note that 'filler' is always set to '0' (see add_mda() - memset),
so use of this area as a non-zero flags field is a safe way to
provide future code features.
