Fully support old windows 8ib user space virtual memory

Addresses are converted in blocks(asan, automap, stack, ...), with the start and end addresses modified using (address & 0xffffff) | ((address >> 28) << 24).

Following addresses are only specified to frame accuracy with the last 4 hex digits chopped off.
null, loader, image and arena blocks have not been modified.
asan     [0x00007fff, 0x10007fff] ⇒ [0x00007fff, 0x01007fff] Not currently supported.
automap  [0x10008004, 0x1fe7fffb] ⇒ [0x01008004, 0x01e7fffb]
_mmi     [0x1fe7fffc, 0x1ffffffb] ⇒ [0x01e7fffc, 0x01fffffb] Listed as memtrack outside of the memtrack files.
fixedmap [0x30000004, 0x40000003] ⇒ [0x03000004, 0x04000003]
nsync    [0x6fc00004, 0x6fcffffb] ⇒ [0x06c00004, 0x06cffffb]
zipos    [0x6fd00004, 0x6fdffffb] ⇒ [0x06d00004, 0x06dffffb] I don't think this is used currently on the vista branch.
g_fds    [0x6fe00004, 0x6feffffb] ⇒ [0x06e00004, 0x06effffb]
winargs  [0x6ffffffe, 0x6fffffff] ⇒ [0x06fffffe, 0x06ffffff] Not entirely confident on if this is accurate.
stack    [0x70000000, 0x70000003] ⇒ [0x07000000, 0x07000003] Not entirely confident on if this is accurate.

This map is documented in memtrack64-8tib.txt with the original 128tib version renamed to memtrack64-128tib.txt.

Modified windows 8.1 check macro name to match existing windows 10 one.
Modified IsShadowFrame to correctly identify the asan block on old windows. Required as the asan block on 128tib virtual memory systems is larger than 2^43 - 1 and so all blocks were reporting as asan.

+/* To create a closure, declare a closure constructor with the right function arguments.
+
+   For functions taking no arguments, use
+	CLOSURE_DECL_BODY0 (foo)
+   to generate the static routine:
+	static closure *closure_foo (void (*f) (void));
+   that will return a closure for any function *f that takes no argument.
+
+   For an 1-argument function, use
+	CLOSURE_DECL_BODY1 (foo, type)
+   to generate the static routine:
+	static closure *closure_foo (void (*f) (type), type x);
+   that will return a closure for any function taking a single argument of the

+	// by writing:
+	CLOSURE_DECL_BODY4 (qsort_args, void *, size_t, size_t, int (*)(const void *, const void *))
+
+	// Second, for each closure to be created, write something like this:
+	closure *cl = closure_qsort_args (array, n_elements, sizeof (array[0]), &elem_cmp);
+
+	// Then to run (and free) each closure:
+	closure_run (cl);
+	// This is like calling
+	//      qsort (array, n_elements, sizeof (array[0]), &elem_cmp);
+	//      free (cl);

-𝐍𝐀𝐌𝐄
-     𝘀𝗰𝗿𝗶𝗽𝘁 — make typescript of terminal session
-
-𝐒𝐘𝐍𝐎𝐏𝐒𝐈𝐒
-     𝘀𝗰𝗿𝗶𝗽𝘁 [-𝗮𝗱𝗲𝗳𝗸𝗽𝗾𝗿] [-𝐅 p̲i̲p̲e̲] [-𝘁 t̲i̲m̲e̲] [f̲i̲l̲e̲ [c̲o̲m̲m̲a̲n̲d̲ .̲.̲.̲]]
-
-𝐃𝐄𝐒𝐂𝐑𝐈𝐏𝐓𝐈𝐎𝐍
-     The 𝘀𝗰𝗿𝗶𝗽𝘁 utility makes a typescript of everything printed on your termi‐
-     nal.  It is useful for students who need a hardcopy record of an interac‐
-     tive session as proof of an assignment, as the typescript file can be
-     printed out later with lpr(1).
-
-     If the argument f̲i̲l̲e̲ is given, 𝘀𝗰𝗿𝗶𝗽𝘁 saves all dialogue in f̲i̲l̲e̲.  If no
-     file name is given, the typescript is saved in the file t̲y̲p̲e̲s̲c̲r̲i̲p̲t̲.
-
-     If the argument c̲o̲m̲m̲a̲n̲d̲ is given, 𝘀𝗰𝗿𝗶𝗽𝘁 will run the specified command
-     with an optional argument vector instead of an interactive shell.
-
-     The following options are available:
-
-     -𝗮      Append the output to f̲i̲l̲e̲ or t̲y̲p̲e̲s̲c̲r̲i̲p̲t̲, retaining the prior con‐
-             tents.
-
-     -𝗱      When playing back a session with the -𝗽 flag, do not sleep between
-             records when playing back a timestamped session.
-
-     -𝗲      Accepted for compatibility with u̲t̲i̲l̲-̲l̲i̲n̲u̲x̲ 𝘀𝗰𝗿𝗶𝗽𝘁.  The child com‐
-             mand exit status is always the exit status of 𝘀𝗰𝗿𝗶𝗽𝘁.
-
-     -𝐅 p̲i̲p̲e̲
-             Immediately flush output after each write.  This will allow a user
-             to create a named pipe using mkfifo(1) and another user may watch
-             the live session using a utility like cat(1).
-
-     -𝗸      Log keys sent to the program as well as output.
-
-     -𝗽      Play back a session recorded with the -𝗿 flag in real time.
-
-     -𝗾      Run in quiet mode, omit the start, stop and command status mes‐
-             sages.
-
-     -𝗿      Record a session with input, output, and timestamping.
-
-     -𝘁 t̲i̲m̲e̲
-             Specify the interval at which the script output file will be
-             flushed to disk, in seconds.  A value of 0 causes 𝘀𝗰𝗿𝗶𝗽𝘁 to flush
-             after every character I/O event.  The default interval is 30 sec‐
-             onds.
-
-     The script ends when the forked shell (or command) exits (a c̲o̲n̲t̲r̲o̲l̲-̲D̲ to
-     exit the Bourne shell (sh(1)), and e̲x̲i̲t̲, l̲o̲g̲o̲u̲t̲ or c̲o̲n̲t̲r̲o̲l̲-̲D̲ (if i̲g̲n̲o̲r̲e̲e̲o̲f̲
-     is not set) for the C-shell, csh(1)).
-
-     Certain interactive commands, such as vi(1), create garbage in the type‐
-     script file.  The 𝘀𝗰𝗿𝗶𝗽𝘁 utility works best with commands that do not ma‐
-     nipulate the screen.  The results are meant to emulate a hardcopy terminal,
-     not an addressable one.
-
-𝐄𝐍𝐕𝐈𝐑𝐎𝐍𝐌𝐄𝐍𝐓
-     The following environment variables are utilized by 𝘀𝗰𝗿𝗶𝗽𝘁:
-
-     SCRIPT
-            The SCRIPT environment variable is added to the sub-shell.  If
-            SCRIPT already existed in the users environment, its value is over‐
-            written within the sub-shell.  The value of SCRIPT is the name of
-            the t̲y̲p̲e̲s̲c̲r̲i̲p̲t̲ file.
-
-     SHELL  If the variable SHELL exists, the shell forked by 𝘀𝗰𝗿𝗶𝗽𝘁 will be
-            that shell.  If SHELL is not set, the Bourne shell is assumed.
-            (Most shells set this variable automatically).
-
-𝐒𝐄𝐄 𝐀𝐋𝐒𝐎
-     csh(1) (for the h̲i̲s̲t̲o̲r̲y̲ mechanism)
-
-𝐇𝐈𝐒𝐓𝐎𝐑𝐘
-     The 𝘀𝗰𝗿𝗶𝗽𝘁 command appeared in 3.0BSD.
-
-     The -𝗱, -𝗽 and -𝗿 options first appeared in NetBSD 2.0 and were ported to
-     FreeBSD 9.2.
-
-𝐁𝐔𝐆𝐒
-     The 𝘀𝗰𝗿𝗶𝗽𝘁 utility places 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴 in the log file, including linefeeds
-     and backspaces.  This is not what the naive user expects.
-
-     It is not possible to specify a command without also naming the script file
-     because of argument parsing compatibility issues.
-
-     When running in -𝗸 mode, echo cancelling is far from ideal.  The slave ter‐
-     minal mode is checked for ECHO mode to check when to avoid manual echo log‐
-     ging.  This does not work when the terminal is in a raw mode where the pro‐
-     gram being run is doing manual echo.
-
-     If 𝘀𝗰𝗿𝗶𝗽𝘁 reads zero bytes from the terminal, it switches to a mode when it
-     only attempts to read once a second until there is data to read.  This pre‐
-     vents 𝘀𝗰𝗿𝗶𝗽𝘁 from spinning on zero-byte reads, but might cause a 1-second
-     delay in processing of user input.
