Srinivas Kandagatla d214655904 fdtput: expand fdt if value does not fit 
If you try to insert a new node or extend a property with large value,
using fdtput you will notice that it always fails.

example:
fdtput -v -p -ts ./tst.dtb "/node-1" "property-1" "value-1
Error at 'node-1': FDT_ERR_NOSPACE

or

fdtput -v -c ./tst.dtb "/node-1"
Error at 'node-1': FDT_ERR_NOSPACE

or

fdtput -v  -ts ./tst.dtb "/node" "property" "very big value"
Decoding value:
	string: 'very big value'
Value size 15
Error at 'property': FDT_ERR_NOSPACE

All these error are returned from libfdt, as the size of the fdt passed
has no space to accomdate these new properties.
This patch adds realloc functions in fdtput to allocate new space in fdt
when it detects a shortage in space for new value or node. With this
patch, fdtput can insert a new node or property or extend a property
with new value greater than original size. Also it packs the final blob
to clean up any extra padding.

Without this patch fdtput tool complains with FDT_ERR_NOSPACE when we
try to add a node/property or extend the value of a property.

Testcases for the new behaviour added by David Gibson.
