e976502216 libgeom(3): note that stdio.h is required when referencing gctl_dump(3)
gctl_dump(3) is only exposed when stdio.h is #include'd first, per its
addition in r112510. The reasoning noted for the conditional "exposure"
of the function was to "limit #include pollution".

This addresses an issue I found with the documentation when looking at
bug 218809, which in turn addresses a -Wimplicit-function-declaration
compiler warning in `tools/regression/geom_gpt/test.c` (it uses
gctl_dump(3)).

- Use .Dv when mentioning NULL per mdoc(7).
- Reword `g_device_path`, `g_open_by_ident`, and `g_providername`'s descriptions
  so they're less wordy.
- Fix a typo in `g_device_path` (can not -> cannot).

7b3ea376a2 META MODE: Prefer INSTALL=tools/install.sh to lessen the need for xinstall.host.
This both avoids some dependencies on xinstall.host and allows
bootstrapping on older releases to work due to lack of at least 'install -l'
support.

4232f82668 Enforce overwritting SHLIBDIR
Since METAMODE has been added, sys.mk loads bsd.mkopt.mk which ends load loading
bsd.own.mk which then defines SHLIBDIR before all the Makefile.inc everywhere.

This makes /lib being populated again.

748e404f26 Since there's no defined schema for the XML that's generated by the
kern.geom.confxml sysctl, it's silly to warn about tags in libgeom,
especially since libgeom exists simply to build a tree out of the conf
information.

019100de26 Back out r233646. Although it fixed most libgeom consumers under 32-bit
compatibility, it broke programs using devstat, under 32-bit compatibility and
not.

It's very difficult to fix the identifiers used by devstat, so this change is
simply being backed out.  Since changes to 3rd-party code seem likely, and may be
necessary to properly fix 32-bit binaries on 64-bit kernel, it would seem better
to make more invasive changes to fix GEOM's problems with 32-bit compatibility in
general.

The right thing to do is to replace all of the use of pointers as opaque
identifiers with a fixed-size (64-bit or even 32-bit should be enough for tracking
unique GEOM elments) field.  That probably maintains source compatibility with
most GEOM consumers, and allows xml2tree to make better assumptions about how to
decode the identifiers.

3dce589cb9 Fix 32-bit libgeom consumers run on 64-bit kernels with COMPAT_FREEBSD32.
Kernel pointer values are used as opaque unique identifiers, which are then
used to reconstruct references between various providers, classes, etc., inside
libgeom from the source XML.  Unfortunately, they're converted to pointer-width
integers (in the form of pointers) to do this, and 32-bit userland pointers
cannot hold sensible representations (however opaque) of 64-bit kernel pointers
on all systems.

In the case where the leading bits are zero and 32 distinct bits of pointer can
be identified, this will happen to work.  On systems where the upper 32-bits of
kernel pointers are non-zero and the same for all kernel pointers, this will
result in double frees and all kinds of bizarre crashes and linkage between
objects inside libgeom.

To mitigate this problem, treat the opaque identifiers in the XML as C strings
instead, and internalize them to give unique and consistent per-object pointer
values in userland for each identifier in the XML.  This allows us to keep the
libgeom logic the same with only minor changes to initial setup and parsing.

It might be more sensible for speed reasons to treat the identifiers as numbers
of a large size (uintmax_t, say) rather than strings, but strings seem fine for
now.

(As an added side-effect, this makes it slightly easier to identify unresolved
 references, but nothing has been added to inform the user of those.)
