- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

sys/rman.h now requires sys/types.h. Include it to make the API match
the man page again.

Collapse devinfo_state_t with device_state_t in order to avoid a
structure replication and improve manteneability.

Use explicit int values for the device states in order to allow,
if necessary, in the future, adds of new states without breaking ABI
between revisions.

Add __BEGIN_DECLS/__END_DECLS so that this header can be included in C++
programs. Also, add include guards.

Expose the new kernel data structures to libdevinfo:
o Added dd_pnpinfo, dd_location, dd_devflags, dd_flags and dd_state
o Copy/initialize these as necessary.
o Document the changes to the interface in devinfo.3.

o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between
architectures.
o Change all headers to make use of this. This mainly involves
changing:
#ifdef _BSD_FOO_T_
typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_
#endif
to:
#ifndef _FOO_T_DECLARED
typedef __foo_t foo_t;
#define _FOO_T_DECLARED
#endif

Made this header self-sufficient.

Fully parenthesized a macro definition.

This is the Device Information Library, libdevinfo.

The devinfo library provides access to the kernel's internal device
hierarchy and to the I/O resource manager. The library uses a
sysctl(9) interface to obtain a snapshot of the kernel's state which
is then made available to the application.
