Changes by Jim Ingham:
* values.c (value_change_enclosing_type): New function. If the
new enclosing type is larger than the old one, we need to allocate
more space.
* value.h: Add value_change_enclosing_type prototype.
* valops.c (value_cast): Use it.
(value_assign): Use it.
(value_addr): Use it.
(value_ind): Use it.
(value_full_object): Use it.

* values.c (value_static_field): Handle static fields that have a constant value.
Abstract out operations specific to particular C++ ABI's, and
invoke them through a function table. This removes the C++ ABI
dependencies scattered throughout the code, and allows us to
cleanly add support for new C++ ABI's.

* c-typeprint.c, c-valprint.c, dbxread.c, eval.c, gdbtypes.c,
jv-typeprint.c, linespec.c, symtab.c, typeprint.c, valops.c:
#include "cp-abi.h". These files all use functions now declared
there.
* symtab.h (OPNAME_PREFIX_P, VTBL_PREFIX_P, DESTRUCTOR_PREFIX_P):
Deleted. These services are now provided by functions declared in
cp-abi.h.

infrun.c mipsread.c nlmread.c os9kread.c parse.c printcmd.c symfile.c
symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c:
Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)
