(CFACT-94) fix processor facts for solaris

Before this patch, there was an inconsistency between facter 2.2 and cfacter in
the count reported, with the count equal to the number of hardware threads
in facter, and equal to the number of cores in cfacter.

This fixes cfacter such that it is similar to facter 2.2

(CFACT-94) fix processor facts for solaris
(maint) Fix scoped_resource to not have a vtable.

If we prevent scoped_resource from being free-store allocated by
deleting new and delete operators, then there's no reason for
scoped_resource to have a virtual destructor.

Additionally, the move semantics weren't correct.  There's no reason to
default construct either the resource and the deleter of the old object.
Instead, simply move them.
(maint) Remove unncessary variable in CMake source lists.

We don't need the verbose use of the CMAKE_CURRENT_LIST_DIR variable in
our source file lists.  The files are already relative to where the list
file.
(CFACT-124) Move os and os_family constants out of POSIX.

Moving the os and os_family constants out of POSIX and into the generic facts
namespace where they can be used by Windows too.
(CFACT-124) Refactor kernel resolver into a base that can be used by Windows.

The base resolver is now responsible for adding the facts.  The POSIX child
type gets the data only.

This will allow us to share the fact definitions between POSIX and Windows.
(maint) Add missing doc comments.

Adding missing doc comments to make doxygen happy.
(CFACT-124) Refactor base DMI resolver so it can be shared by Windows.

Refactoring the base DMI resolver to keep the fact definitions in a
single place (the base).  The child types are only responsible for
returning data to the parent.
(CFACT-124) Refactor filesystem resolver into a base implementation.

Refactoring the filesystem resolver into a base implementation that is
responsible for the fact definition.  Child types are only responsible
for populating the data.
(CFACT-124) Refactor identity resolver into a sharable base.

Refactoring identity resolver into a shared base implementation.  The
base implementation is responsible for adding the facts (single
definition) while the child types are responsible for collecting the
data.
(CFACT-124) Refactor memory resolver into a sharable base.

Refactoring the memory resolver into a common base implementation.  The
base implementation is responsible for the fact definition while the
child types are responsible for collecting the data.
(CFACT-124) Refactor operating system resolver.

Refactoring the operating system resolver into a base that is
responsible for adding the facts and child types that are responsible
for collecting data.  This allows it to be shared with Windows.

This refactoring also merges the LSB resolver in with the operating
system resolver.

Breaking change: some of the names on the os structured fact have
diverged from Facter 2.2 to clean up the less than ideal naming. We need
to investigate if this will be impactful and how to mitigate.
(CFACT-124) Refactor uptime resolver to shared base.

Refactoring the uptime resolver into a shared base implementation that
is responsible for defining the facts while the child types are
responsible for collecting the data.
(CFACT-124) Refactor timezone resolver into base implementation.

Refactoring the timezone resolver into a base implementation that is
responsible for adding the facts and child types that are responsible
for collecting data.
(CFACT-124) Refactor virtualization resolver into base type.

Refactoring the virtualization resolver into a base type that is
responsible for adding the facts and child types that are responsible
for collecting data.
(CFACT-124) Refactor block device resolver.

Refactoring the block device resolver into a base type responsible for
adding the facts and child types that are responsible for collecting
data.

This also adds the "blockdevice" structured fact representing block
device data.  Unfortunately "blockdevices" is an already existing fact
name.
(CFACT-124) Refactor SSH resolver into base type.

Refactoring the SSH resolver into a base type responsible for adding
facts and child types that are responsible for collecting SSH key data.

This also adds the ssh structured fact.
(CFACT-124, CFACT-76) Refactor networking resolver.

Refactor the networking resolver into a base type that is responsible
for adding a fact and child types that are responsible for collecting
data.  This keeps the fact definition in one place and allows Windows to
share the base implementation.

This commit also adds a structured "networking" fact that collects all
networking data into one place.
