* harbour/contrib/xhb/xhb.hbp
* harbour/contrib/xhb/xhb.hbx
+ harbour/contrib/xhb/xhbarrex.c
+ added ASIZEALLOC(), ALENALLOC() xHarbour functions
In Harbour they are in practice useless because we are using
dynamic array preallocation not static one as in xHarbour.
* harbour/doc/xhb-diff.txt
+ added information about HB_ARRAYTOPARAMS() function
