Moved eminline and related files into /src/osd since it's system related (nw)
Moved delegates into /src/lib/util to enable usage of delegates in other project parts Moved mame_printf_* calls into /src/osd/osdcore.c and renamed them to osd_printf_* Changed mess.mak to display compilation of ymmu100.ppm nicely

+
+ delegate.h
+
+ Templates and classes to enable delegates for callbacks.
+
+****************************************************************************
+
+ There are many implementations of delegate-like functionality for
+ C++ code, but none of them is a perfect drop-in fit for use in MAME.
+ In order to be useful in MAME, we need the following properties:
+
+ * No significant overhead; we want to use these for memory
+ accessors, and memory accessor overhead is already the dominant
+ performance aspect for most drivers.
+
+ * Existing static functions need to be bound with an additional
+ pointer parameter as the first argument. All existing
+ implementations that allow static function binding assume the
+ same signature as the member functions.
+
+ * We must be able to bind the function separately from the
+ object. This is to allow configurations to bind functions
+ before the objects are created.
+
+ Thus, the implementations below are based on existing works but are
+ really a new implementation that is specific to MAME.
+
+ --------------------------------------------------------------------
+
+ The "compatible" version of delegates is based on an implementation
+ from Sergey Ryazanov, found here:
+
+ http://www.codeproject.com/KB/cpp/ImpossiblyFastCppDelegate.aspx
+
+ These delegates essentially generate a templated static stub function
+ for each target function. The static function takes the first
+ parameter, uses it as the object pointer, and calls through the
+ member function. For static functions, the stub is compatible with
+ the signature of a static function, so we just set the stub directly.
+
+ Pros:
+ * should work with any modern compiler
+ * static bindings are just as fast as direct calls
+
+ Cons:
+ * lots of little stub functions generated
+ * double-hops on member function calls means more overhead
+ * calling through stub functions repackages parameters
+
+ --------------------------------------------------------------------
+
+ The "internal" version of delegates makes use of the internal
+ structure of member function pointers in order to convert them at
+ binding time into simple static function pointers. This only works
+ on platforms where object->func(p1, p2) is equivalent in calling
+ convention to func(object, p1, p2).
+
+ Most of the information on how this works comes from Don Clugston
+ in this article:
+
+ http://www.codeproject.com/KB/cpp/FastDelegate.aspx
+
+ Pros:
+ * as fast as a standard function call in static and member cases
+ * no stub functions or double-hops needed
+
+ Cons:
+ * requires internal knowledge of the member function pointer
+ * only works for GCC (for now; MSVC info is also readily available)
