#822: Native#loadLibrary requires that the interface class passed in is an instance of Library. The runtime check can be enhanced by using a constraint generic. This breaks binary compatibility (see notes below) - @d-noll.

In a followup, the original loadLibrary methods were deprecated and Native#load methods were introduced, that hold the new generic definitions. So this change is now binary compatible.
#889: The Structure#newInstance receive the target type as a parameter. This adds a limited generic type, so that the return type ist the target type and not a generic structure, removing the necessity to do an explizit cast - @matthiasblaesing.

Native code for platforms with a JDK version lower than 8 can still be build by (demonstrated for Solaris x86):
1. Run `ant -Dbuild.os.name=SunOS -Dbuild.os.arch=x86 native-build-package`
2. Transfer the `build/build-package-sunos-x86-5.2.1.zip` file to the target system. The file holds the native sources, the necessary headers and and a shell script for the build.
3. Expand the zip on the target system.
4. Setup `JAVA_HOME` to point to the JDK sources.
5. Change into the expanded directory and run `bash build.sh`.
6. The resulting `sunos-x86.jar` is copied back to the original build system to `lib/native/sunos-x86.jar`
- [@matthiasblaesing](https://github.com/matthiasblaesing).
#958: Update for PR 863: Old toolchains produce binaries without hard-/softfloat markers. Rasbian is missing the markers and the oracle JDK is also affected. For hardfloat detection now also the Arm EABI section is also considered - @matthiasblaesing.
#974: If the callback code failed to attach to the JVM, this lead to a segfault. The success of attaching to the JVM was checked to late and an invalid JNIEnv pointer was used to access the JVM - @matthiasblaesing.
#1010: Fix binding of lpAccessName parameter of com.sun.jna.platform.win32.Mpr#WNetUseConnection - @matthiasblaesing.
#384: Switch default value for jna.nosys to true. By default then the embedded native library is used - @matthiasblaesing.

Breaking Changes

com.sun.jna.Pointer#SIZE is removed. Its use is replaced by com.sun.jna.Native#POINTER_SIZE to prevent a class loading deadlock, when JNA is initialized from multiple threads
com.sun.jna.Pointer#getString(long offset, boolean wide) is removed. It was replaced by com.sun.jna.Pointer#getString(long offset) or com.sun.jna.Pointer#getWideString(long offset)
com.sun.jna.Pointer#getStringArray(long offset, boolean wide) is removed. It was replaced by com.sun.jna.Pointer#getStringArray(long offset) or com.sun.jna.Pointer#getWideStringArray(long offset)
com.sun.jna.Pointer#setString(long offset, String value, boolean wide) is removed. It was replaced by com.sun.jna.Pointer#setString(long offset, String value) or com.sun.jna.Pointer#setWideString(long offset, String value)
com.sun.jna.Structure#setFieldOrder is removed. It was replaced by com.sun.jna.Structure#getFieldOrder and threw an java.lang.Error on call.
com.sun.jna.Native#parseVersion was removed without replacement
com.sun.jna.Native#setPreserveLastError and com.sun.jna.Native#getPreserveLastError were removed without replacement. They were turned into NOOPs in the past.
com.sun.jna.Native#getDirectByteBuffer was replaced by com.sun.jna.Pointer#getByteBuffer
the parameters of the methods gethostname, sethostname, getdomainname and setdomainname in the interface com.sun.jna.platform.unix.LibCAPI were changed from (char[] name, int len) to (byte[] name, int len)
com.sun.jna.Platform#isAix was replaced by com.sun.jna.Platform#isAIX
com.sun.jna.platform.win32.Sspi.SecBufferDesc was incompatibly changed to match the correct native semantics. SecBufferDesc describing more than one buffer were broken. For most usecases com.sun.jna.platform.win32.SspiUtil.ManagedSecBufferDesc is the best alternative.
com.sun.jna.platform.win32.WinBase.FILETIME#toLong() was replaced by com.sun.jna.platform.win32.WinBase.FILETIME#toTime()
com.sun.jna.platform.win32.Variant#COM_DAYS_ADJUSTMENT was removed
com.sun.jna.platform.win32.Variant#MICRO_SECONDS_PER_DAY was removed
com.sun.jna.platform.win32.Variant.VARIANT#toJavaDate was removed
com.sun.jna.platform.win32.Variant.VARIANT#fromJavaDate was removed
com.sun.jna.platform.win32.User32#MonitorFromPoint(Point pt, int dwFlags) was replaced by com.sun.jna.platform.win32.User32#MonitorFromPoint(Point.ByValue pt, int dwFlags)
com.sun.jna.platform.win32.OleAuto.LoadTypeLib(WString, PointerByReference) was replaced by com.sun.jna.platform.win32.OleAuto.LoadTypeLib(String, PointerByReference)
com.sun.jna.platform.win32.Kernel32Util.formatMessageFromHR(HRESULT) was replaced by com.sun.jna.platform.win32.Kernel32Util.formatMessage(HRESULT)
com.sun.jna.platform.win32.COM.COMException was structurally modified. The pExcepInfo and puArgErr members were removed and hresult member was added. The now missing information in COMException was moved to COMInvokeException.
The third parameter of com.sun.jna.platform.win32.COM.IShellFolder#GetDisplayNameOf was changed from PointerByReference to STRRET and matching this, the first parameter of com.sun.jna.platform.win32.Shlwapi.StrRetToStr was changed identically.
ACE_HEADER replaces ACEStructure as the base class for ACEs. com.sun.jna.platform.win32.WinNT.ACL was modified to support ACLS, that contain ACEs other than ACCESS_ALLOWED_ACE_TYPE and ACCESS_DENIED_ACE_TYPE by widening the return type of getACEStructures to ACE_HEADER[] and renaming the method to getACEs. In consequence com.sun.jna.platform.win32.Advapi32Util#getFileSecurity was changed similarly. The SID accessors getSidString and getSID were moved from ACEStructure to ACCESS_ACEStructure.
com.sun.jna.platform.win32.Ole32#CoCreateGuid(GUID.ByReference pguid) was replaced by com.sun.jna.platform.win32.Ole32#CoCreateGuid(GUID pguid) and com.sun.jna.platform.win32.Ole32#CLSIDFromString(WString lpsz, CLSID.ByReference pclsid) was replaced by com.sun.jna.platform.win32.Ole32#CLSIDFromString(String lpsz, CLSID.ByReference pclsid)
