Remove some admin/notes files

* admin/notes/lel-TODO: Remove.  This has not turned out to be a
useful way to get things documented.

* admin/notes/exit-value, admin/notes/iftc: Remove.
These don't seem to have any particular relationship to Emacs development.

-Iso-Functional Type Contour
-
-
-This is a term coined to describe "column int->float" change approach, and can
-be used whenever low-level types need to change (hopefully not often!) but the
-meanings of the values (whose type has changed) do not.
-
-The premise is that changing a low-level type potentially means lots of code
-needs to be changed as well, and the question is how to do this incrementally,
-which is the preferred way to change things.
-
-Say LOW and HIGH are C functions:
-
-  int LOW (void) { return 1; }
-  void HIGH (void) { int value = LOW (); }
-
-We want to convert LOW to return float, so we cast HIGH usage:
-
-  float LOW (void) { return 1.0; }
-  void HIGH (void) { int value = (int) LOW (); }  /* iftc */
-
-The comment /* iftc */ is used to mark this type of casting to differentiate
-it from other casting.  We commit the changes and can now go about modifying
-LOW and HIGH separately.  When HIGH is ready to handle the type change, the
-cast can be removed.
