hexdump: introduce test suite 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.

lib/test-hexdump.c: fix initconst confusion const char *...[] is not const, but an array of pointer to const. So these arrays cannot be __initconst, but must be __initdata This fixes section conflicts with LTO.

hexdump: Make test data really const The test data arrays, containing pointers to test strings, are never modified, so they can be const, too. Hence mark them "const" and "__initconst". This moves 28 pointers from ".init.data" to ".init.rodata".

hexdump: avoid warning in test function The test_data_1_le[] array is a const array of const char *. To avoid dropping any const information, we need to use "const char * const *", not just "const char **". I'm not sure why the different test arrays end up having different const'ness, but let's make the pointer we use to traverse them as const as possible, since we modify neither the array of pointers _or_ the pointers we find in the array.

hexdump: make it return number of bytes placed in buffer 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.
