DebCheck QA: Passing value -1 to sqrt() leads to undefined result

(see #1311)

• ./vector/v.mapcalc/vector.c:127 [error] - Passing value -1 to sqrt() leads to undefined result

(v.mapcalc? anyone ever play with this code??)

v.mapcalc should be svn moved out to GRASS Addons.

sqrt(-1) to set nan value replaced by 0.0/0.0 in devbr6 and trunk with r50193-5.

nan creation backported to relbr64 in r57770, closing ticket.

Some more fixes applied so now it builds in all branches (need to run make twice in 6.x as it's missing some Makefile target prereq).

Unless someone wants to take it up, recommend to move trunk's v.mapcalc code into addons svn since the module remains a work in progress.
