'best' ABI
- Use 'os.arch' as a prelim CPUType for MachineDescription
- Always attempt to load a binary and parse it's elf header
- Linux: self-exe
- Android: gluegen-rt library
- Other: java lib
- Always use details (ABI) if ARM
- Android: Check CPU_TYPE and CPU_TYPE2
// FIXME / HACK:
// We use sCPUType for MachineDescriptionRuntime.getStatic()
// until we have determined the final CPU_TYPE, etc.
// MachineDescriptionRuntime gets notified via MachineDescriptionRuntime.notifyPropsInitialized() below.
//
// We could use Elf Ehdr's machine value to determine the bit-size
// used for it's offset table!
// However, 'os.arch' should be a good guess for this task.
Tested manually on
- Linux x86, x86_64, armhf (raspi)
- Android intel and arm
- Windows x86_64
- OSX x86_64

converting to file-path or URI (Windows UNC / share host)
Note: Authority for 'file-scheme' URI's is used on Windows to denote the host of the shared resource -> UNC
Following methods of IOUtil didn't consider the authority for file-scheme URI:
'URL toURL(final URI uri)'
'String decodeURIToFilePath(final String uriPath)'
'String decodeURIIfFilePath(final URI uri)'
Further more, the patterns 'patternSingleFS' and 'patternSingleBS'
converted multiple '\' '/' to one replacement.
However, we should not change the separator count and replace them one-by-one.
TestIOUtilURIHandling:
- Added shared-file-host 'filehost' test cases to file URIs and plain file path tests.
- Passed on Unix and Windows.
Added 'make/scripts/test-win32-smb_share.bat'
- Testing actual windows share usage
- Passed on Windows

/proc/self/exe (Linux) or a found java/jvm native lib.
- PlatformPropsImpl.queryABITypeImpl: Check Elf Header for ARM + !ANDROID (i.e. add other OS than Linux, use native java/jmv lib)
- NativeLibrary.enumerateLibraryPaths: Add 'sun.boot.library.path' to enumeration!
- TestElfReader01: Add test for finding java/jvm native lib and parse it

- Fin
MachineDesction == MD
MD.StaticConfig:
- enum for all supported static configs (ID -> MD)
- verified at runtime: test runtime queried-MD versus static-MD,
hard fail if not compatible (size/alignment)
SizeThunk primitive sizes:
- Add notion of fixed native size (eg. int64_t) and otherwise (eg. long)
java struct 'wrappers' code generation:
- single class using size/offset arrays of all MachineDescription configurations
- at runtime the array idx is queried in static block
- type aligment for not fixed-native-size types (SizeThunk, undef long/int) via StructAccessor
junit test:
- add float test
- fix native code
- add java (create, write) -> native (verify) test
works (tested) on: linux 32/64 and windows 32/64
