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.
-replace '/1024*8192/1024' with '/128'

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.

Non-x86 architectures (namely PA-RISC) may not have the "cache size" line, but
others. Search for all and sum up their results.

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.

We no longer support Windows 98.  Remove Win9x-specific code and
supporting infrastructure.  This simplifies the implementation in several
places.

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.

Replace accidental use of kwsys_stl:: with kwsys_ios:: to reference
string streams.  The former is the namespace for STL, the latter for
streams.
