Subject: [PATCH 3/9] Fix a bug in NSMapTable.

In the simple constructors, we were using the pointer functions that use
pointer equality and a hash derrived from the pointer, rather than -isEqual:
and -hash.  This led to some subtle and confusingly broken behavior.

Subject: [PATCH 4/9] Refactor refcount usage.

This makes it easier for the runtime to change how reference counts are
stored by removing any refcount manipulation from -base when the runtime
provides accessors.  This should have no functionality change with
existing runtimes, but will let newer runtimes drop in alternative
representations easily.

Subject: [PATCH 8/9] Refactor weak symbol usage.

The Linux run-time linker doesn't allow weak references in one library
to be overridden by ones in another.  To work around this, we now
declare the runtime functions as weak and perform dynamic checks on
whether the symbols have been resolved and call the fallbacks as local
static functions if they are not present.

+	* Source/NSObject.m:      Refactor refcount usage.
+
+	This makes it easier for the runtime to change how reference
+	counts are
+	stored by removing any refcount manipulation from -base when
+	the runtime
+	provides accessors.  This should have no functionality
+	change with
+	existing runtimes, but will let newer runtimes drop in
