91a1b8d634 NOTE: This change requires two new osd functions: osd_malloc() and
osd_free(). They take the same parameters as malloc() and free().

Renamed mamecore.h -> emucore.h.

New C++-aware memory manager, implemented in emualloc.*. This is a
simple manager that allows you to add any type of object to a
resource pool. Most commonly, allocated objects are added, and so
a set of allocation macros is provided to allow you to manage
objects in a particular pool:

  pool_alloc(p, t) = allocate object of type 't' and add to pool 'p'
  pool_alloc_clear(p, t) = same as above, but clear the memory first
  pool_alloc_array(p, t, c) = allocate an array of 'c' objects of type
                              't' and add to pool 'p'
  pool_alloc_array_clear(p, t, c) = same, but with clearing
  pool_free(p, v) = free object 'v' and remove it from the pool

Note that pool_alloc[_clear] is roughly equivalent to "new t" and
pool_alloc_array[_clear] is roughly equivalent to "new t[c]". Also
note that pool_free works for single objects and arrays.

There is a single global_resource_pool defined which should be used
for any global allocations. It has equivalent macros to the pool_*
macros above that automatically target the global pool.

In addition, the memory module defines global new/delete overrides
that access file and line number parameters so that allocations can
be tracked. Currently this tracking is only done if MAME_DEBUG is
enabled. In debug builds, any unfreed memory will be printed at
the end of the session.

emualloc.h also has #defines to disable malloc/free/realloc/calloc.
Since emualloc.h is included by emucore.h, this means pretty much
all code within the emulator is forced to use the new allocators.
Although straight new/delete do work, their use is discouraged, as
any allocations made with them will not be tracked.

Changed the familar auto_alloc_* macros to map to the resource pool
model described above. The running_machine is now a class and contains
a resource pool which is automatically destructed upon deletion. If
you are a driver writer, all your allocations should be done with
auto_alloc_*.

Changed all drivers and files in the core using malloc/realloc or the 
old alloc_*_or_die macros to use (preferably) the auto_alloc_* macros 
instead, or the global_alloc_* macros if necessary.

Added simple C++ wrappers for astring and bitmap_t, as these need
proper constructors/destructors to be used for auto_alloc_astring and
auto_alloc_bitmap.

Removed references to the winalloc prefix file. Most of its 
functionality has moved into the core, save for the guard page 
allocations, which are now implemented in osd_alloc and osd_free.
