prep CHANGES for the next release of calc

Removed use of HAVE_MEMMOVE as well have_memmv.c.  Removed the
building and including of have_memmv.h.  Removed the memmove()
function in blkcpy.c, used when HAVE_MEMMOVE was NOT defined.
The libc memmove(3) function as defined by <string.h> is now
required to compile calc because the replacement code in
blkcpy.c q was problematic, especially when regions overlap.
The HAVE_MEMMOVE make symbol was removed from Makefile.config.
Thanks to GitHub user @skeeto for reporting this problem.

+The following are the changes from calc version 2.15.1.2 to 2.15.1.2:

+    The HAVE_MEMMOVE make symbol was removed from Makefile.config.
+    Thanks to GitHub user @skeeto for reporting this problem.
+
+
+The following are the changes from calc version 2.15.1.1 to 2.15.1.1:
+
+    Change Makefile.config to, if not using not HomeBrew, then try to
+    detect macports and/or using /opt/local/{lib,include}.
+
+    Put full date range (1989-2025) of calc source into version.h.
+
+    Version 2.16.0.0 will form the basis for the calc v2 to calc v3 fork.
+
+
+The following are the changes from calc version 2.15.0.7 to 2.15.1.0:
+
+    Converted all ASCII tabs to ASCII spaces using a 8 character
+    tab stop, for all files, except for all Makefiles (plus rpm.mk).
+    The command `git diff -w` reports no changes.  There is no
+    functionality change in calc: only ASCII tabs to ASCII spaces.
+
+    Fixed trailblank.  It was pruning . in its find search.
+    Added check for ASCII tabs is non-Makefiles.
+
+
+The following are the changes from calc version 2.15.0.6 to 2.15.0.7:
+
+    Thanks to GitHub user @bambooleafz a critical bug (GitHub issue
+    #148 - https://github.com/lcn2/calc/issues/148) they identified
+    was fixed.
+
+
+The following are the changes from calc version 2.15.0.5 to 2.15.0.6:
+
+     Thanks to GitHub user @ashamedbit, a long standing memory leak in
+     zrandom.c has been fixed.
+
+
 The following are the changes from calc version 2.15.0.4 to 2.15.0.5:
 
      make clobber now removes the legacy files: have_fpos.h, help/man,
