Rolf Eike Beer 3022f2a1ef cmELF: fix signedness warning on OpenBSD
OpenBSD defines Elf64_Dyn::d_tag to be of an unsigned type, which differs from
what most other platforms do and what is the case for 32 bit. To have the tag
as unsigned makes sense, but this causes a compilation warning:

/.../CMake/Source/cmELF.cxx: In member function 'const cmELF::StringEntry* cmELFInternalImpl<Types>::GetDynamicSectionString(int) [with Types = cmELFTypes64]':
/.../CMake/Source/cmELF.cxx:945:   instantiated from here
/.../CMake/Source/cmELF.cxx:668: warning: comparison between signed and unsigned integer expressions

Add an explicit typedef to cast the value to for 32 and 64 bit. That type is
unsigned and has the proper length for both platforms so no information is
lost. Explicitely cast both arguments before comparing them to avoid the
warning in all situations.

Clinton Stimpson 5730710c86 Use cmsys::[io]fstream instead of cmsys_ios::[io]fstream.
Also use SystemTools::Fopen() instead of fopen().
This is to eventually support utf-8 filenames.

David Coppa 480e924dae OpenBSD: Enable ELF parsing and editing (#14241)
OpenBSD provides ELF ABI declarations in

 #include <stdint.h>
 #include <elf_abi.h>

Teach the platform check and cmELF implementation to use these.

Brad King 6fc4cd8680 Fix or cast integer conversions in cmake
These were revealed by GCC's -Wconversion option.  Fix types where it is
easy to do so.  Cast in cases we know the integer will not be truncated.

Brad King 96afb12087 Convert CMake to OSI-approved BSD License
This converts the CMake license to a pure 3-clause OSI-approved BSD
License.  We drop the previous license clause requiring modified
versions to be plainly marked.  We also update the CMake copyright to
cover the full development time range.

Brad King 0c20967a6b BUG: Fix operator precedence error in cmELF
When attempting to load the RPATH out of a non-ELF file cmELF would
crash because the check for a valid file was done with in correct
operator precedence.  See bug#7392.

Brad King d707719d57 ENH: In cmELF it is okay if the byte order is not known at compile time.
- We perform a runtime check of the input file anyway.
