*	hexdump: make it return number of bytes placed in buffer	Andy Shevchenko	2015-02-13	1	-0/+45
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	This patch makes hexdump return the number of bytes placed in the buffer excluding trailing NUL. In the case of overflow it returns the desired amount of bytes to produce the entire dump. Thus, it mimics snprintf(). This will be useful for users that would like to repeat with a bigger buffer.

*	hexdump: introduce test suite	Andy Shevchenko	2015-02-13	1	-0/+135
	Test different scenarios of function calls located in lib/hexdump.c. Currently hex_dump_to_buffer() is only tested and test data is provided for little endian CPUs.
