Hi,
I have added and attached the work mentioned in my original dealing
with Marshal.AllocCoTaskMem and Marshal.AllocHGlobal.
The problem I am trying to solve is the same as before. Our
application expects to use its own allocator for these calls, not
g_malloc and g_free.
monomarshalhooks5.patch contains all the changes for BSTR, CoTaskMem
and HGlobal, but I will commit the BSTR fix first and then other
allocator changes second.

* marshal-hooks.h : Adding declaration for
mono_install_alloc_hglobal_funcs and
mono_install_alloc_cotaskmem_funcs.
* marshal.c : Adding mono_install_alloc_hglobal_funcs to override alloc,
realloc and free functions for HGlobal
* marshal.c : Adding mono_install_alloc_cotaskmem_funcs to override
alloc,
realloc and free functions for CoTaskMem
