noaccess, writable, readable, other
Now they are:
noaccess, undefined, defined, partdefined
As a result, the following names:
make_writable, make_readable,
check_writable, check_readable, check_defined
have become:
make_mem_undefined, make_mem_defined,
check_mem_is_addressable, check_mem_is_defined, check_value_is_defined
(and likewise for the upper-case versions for client request macros).
The old MAKE_* and CHECK_* macros still work for backwards compatibility.
This is much better, because the old names were subtly misleading. For
example:
- "readable" really meant "readable and writable".
- "writable" really meant "writable and maybe readable, depending on how
the read value is used".
- "check_writable" really meant "check writable or readable"
The new names avoid these problems.
The recently-added macro which was called MAKE_DEFINED is now
MAKE_MEM_DEFINED_IF_ADDRESSABLE.
I also corrected the spelling of "addressable" in numerous places in
memcheck.h.

use a custom-allocator and detect almost as many errors as you could detect if
you used malloc/new/new[]. (eg. leaks detected, free errors, free mismatch,
etc).
Had to fiddle with mac_malloc_wrappers.c a bit to factor out the appropriate
code to be called from the client request handling code. Also had to add a
new element `MAC_AllocCustom' to the MAC_AllocKind type.
Also added a little documentation, and a regression test.
