[PATCH v4 00/12] fs/seq_file: introduce seq_hex_dump() helper

This introduces a new helper and switches current users to use it. All are
compiled tested, hexdump and kmemleak are tested by their test suits.

Changelog v4:
- hexdump is amended to return value from which we can check an overflow
(patches 1/12 - 4/12)
- seq_hex_dump pushes bytes directly to buffer and returns an error in case of
overflow (addresses Al Viro's comment)
- append Acked-by for patches 8/12 and 9/12
- convert more users (patches 10/12 - 12/12)

Changelog v3:
- append Mauro's Ack
- rebase on top of recent linux-next

Changelog v2:
- append Acked-by and Reviewed-by tags
- update commit messages in patches 3/5. and 5/5
- update line size to be 32 bytes instead of 16 in patch 3/5
- Joe found that output is changed in patch 4/5, thus I update commit message
there
