  SystemInformation: query memory size with sysconf() on Solaris
  SystemInformation: count processors with sysconf() on Solaris
  SystemInformation: factor out QueryProcessorBySysconf()
  SystemInformation: factor out QueryMemoryBySysconf()

The manpage suggests this is available since Solaris 2.3, which is from
1993. No need to spawn a process then for this information. As an extra
bonus we get information about the available physical memory for free,
which was missing before. On 32 bit processes we will still fall back
to the old method as the values returned by a 32 bit process on a 64
bit host are limited to 4 GiB.

Rename QuerySolarisInfo() to QuerySolarisProcessor() as that is now what
this function is about.

Append the whole process output in one go to our buffer instead of doing
this byte by byte.

kwsysProcess_WaitForData() may return kwsysProcess_Pipe_Timeout, which
is 255. The current check would take that as sign of success and read
invalid data or even crash.

The parent commit removed a useless if condition but forgot to leave
behind the behavior from either path.  Add the missing assignment from
the original else block.

The other query functions return bool and the only values ever returned
here were 0 and 1 anyway.

This was used only at a single place since commit 3db65ac1
(SystemInformation: wrap the call to CPUID in a function), so there is
no need to keep this abstracted anymore.

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.

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.
