In commit bf7f0ddc (Fix KWSys FundamentalType for Universal Binaries,
2009-11-20) we repurposed CMake variables "KWSYS_SIZEOF_${type}" and
dropped use of them from configured headers.  However, use of one was
accidentally left in "IOStream.hxx.in" to record whether the compiler
supports 'long long'.  Replace it with a better test.

Without this, "@KWSYS_SIZEOF_LONG_LONG@" is replaced with "TRUE" which
the preprocessor may evaluate as "0" or "1" depending on whether a
"TRUE" macro is defined.

* changes:
  SystemInformation: use /proc/cpuinfo only when present
  SystemInformation: determine CPU type on HP-UX
  SystemInformation: count CPUs on HP-UX
  SystemInformation: query memory size, CPU count, and CPU speed on BSD

The CPU may have a TSC but reading it may fail, in which case we now always
fall back to reading the value from the registry. This is especially true
on Windows64 where we do not have the assembler instructions at all.

Remove logic that skips all slashes before the first ':'.  This does not
even make sense for Windows drive letter handling.  While at it, remove
no-op logic that appears to try to remove trailing slashes.

Try to open /proc/cpuinfo only on platforms where it's presence is
expected, namely Linux and Cygwin.

Otherwise try sysconf(_SC_NPROCESSORS_ONLN) as last resort to count
processors. Also account for the slightly different name on IRIX.

-do not always set NumberOfLogicalCPU to 1, it doesn't make any sense
 to have this number smaller than NumberOfPhysicalCPU. Instead keep
 both numbers the same and set LogicalProcessorsPerPhysical to 1.

E.g. Linux ARM platforms write "CPU architecture" instead of "cpu family".

GetExtendedProcessorName() may sometimes return "Unknown family" when
we could return something more meaningful. Some systems (e.g. PA-RISC
on Linux) export a "cpu" value in /proc/cpuinfo that has a beautified
processor name in it (e.g. "PA8600 (PCX-W+)"). If we have not found
something nice but this field is present use that information.

If the given key (e.g. "cpu") is matched at the beginning of any line the value
was returned regardless if that line would be the correct match (e.g.
"cpu family" is not the correct line). Make sure between the key and the colon
are only spaces and tabs.

The Registry class is not used by any other part of KWSys or by any of
the major dependent projects (CMake, ITK, VTK, ParaView, etc.).  Remove
it from KWSys proper.  It can be kept in a specific dependent if
necessary.

Some compilers, notably Clang, will warn at compile time (or
runtime with debug flags) if they detect a null dereference.
Try to outsmart them by dereferencing an address a little
larger than NULL.

In order to compute FQDN portably in the future we will need an
incremental series of try_compile tests to build up the list of
available headers and supported APIs.  For now implement it only on
platforms where we have already hard-coded preprocessor tests for the
headers.

Commit 857bda17 (SystemInformation: Report more information, 2012-05-29)
attempted to refactor the internal CallSwVers helper to avoid duplicate
code but introduced a regression in output parsing.  Run sw_vers using
our RunProcess helper rather than popen and restore the original output
processing approach.

Add methods to report host memory total, host memory available,
process memory available, host memory used, and process memory
used. In this context memory is unavailable if there are resource
limits in place that would prevent its use. Such resource limits
assumed to be applied on a per host basis both to cooperatively
operating process groups, such as mpi programms running in parallel,
and to individual processes. When reporting host memory available
consult an application specified environment variable. When reporting
process memory available consult unix resource rlimits and an
application specified environment variable. The environmant variables
provide a means of communicating resource limits that are being
applied in a non-standard way.
