Move the implementation of print_hex_dump() into linux_compat.c as lkpi_hex_dump() taking an extra function pointer and argument. Add two internal wrappers for printf and sbuf_printf to get a common function definition (sbuf_printf takes the extra argument). Use these to implement print_hex_dump() and the newly added seq_hex_dump(). This allows us to re-use the same implementation of print_hex_dump() for both functions without duplicating the code. Initial implementation: D49381 by dumbbell Sponsored by: The FreeBSD Foundation Reviewed by: dumbbell Differential Revision: https://reviews.freebsd.org/D49637 (cherry picked from commit 4359672e656af5e6758d0aae147212e58f445f5b)
