Bug#10963: LEFT/RIGHT/SUBSTR/.. string functions returns wrong result \ 

  on large length
  
Problem:  Most (all) of the numeric inputs were being coerced into
int (32 bit) sized variables.  Works OK for sane inputs; any input
larger than 2^32 (or 2^31 for signed vars) exihibited predictable
wrapping behavior (up to about 10^18) and then started having really
strange behaviour past that point (since the conversion to 64 bit int
from the DECIMAL type can do weird things on out of range numbers).

Solution: 1)  Add many tests.  2)  Convert input from (u)long type to
(u)longlong.  3)  Do (sometimes multiple) sanity checks on input,
keeping in mind that sometimes a negative longlong is not a negative
longlong (if the unsigned_flag is set).  4) Emulate existing behavior
w/rt negative and "small" out-of-bounds values.
