MFC r242130:

Improve libgeom XML parsing error handling.

- Abort parsing and return an error if we run out of memory.
- Return EILSEQ from geom_xml2tree() for XML syntax errors.

Copy head to stable/9 as part of 9.0-RELEASE release cycle.

Remove stale link.

PR: 151252

Remove code duplication by introducing static gctl_param_add() function which
is now used by both gctl_ro_param() and gctl_rw_param().

- Simplify gctl_get_handle() a bit.
- Prefer 'unsigned int' over 'u_int' in userland code.

Handle null return from XML_ParserCreate and fix a few memory leaks on
error conditions.

- Simplify the procedure of retrieving XML-data from the kernel.
- Fix a number of potential memory leaks in libgeom related to doing realloc
without freeing old pointer if things go wrong.
- Fix a number of places in libgeom where malloc and calloc return values
were not checked.
- Check malloc return value and provide sufficient warning messages when XML
parsing fails.

Use 'dowrite' as an argument name instead of too general 'write'.

Remove parameter names from prototypes to avoid namespace issues.

Implement and document some utility functions that can be used to communicate
with GEOM providers.

Second call of sysctl() is used to gather a proper size of a memory chunk
needed to hold the GEOM tree. At this point, pointer 'p' has an improper
value (as it was used previously), and we're getting EFAULT. Fix this
functionality by passing NULL instead of 'p'.

This fixes mdconfig(8) -l output with high number of md(4) devices.

Markup, grammar, punctuation.

Make libgeom usable by C++ programs:
- Add DECL wrappers to libgeom.h.
- Rename structure members in libgeom.h to use a lg_ prefix for member
names. This is required because a few structures had members named
'class' which made g++ very unhappy.
- Catch gstat(8) and gconcat(8) up to these API changes.

Stage 3 of dynamic root support. Make all the libraries needed to run

reside in /lib, the .so symlink continues to live /usr/lib so the
