ss is able to print the map ID(s) for which a given socket has BPF socket-local storage defined (using --bpf-maps or --bpf-map-id=). However, the actual content of the map remains hidden. This change aims to pretty-print the socket-local storage content following the socket details, similar to what `bpftool map dump` would do. The exact output format is inspired by drgn, while the BTF data processing is similar to bpftool's. ss will use libbpf's btf_dump__dump_type_data() to ease pretty-printing of binary data. This requires out_bpf_sk_storage_print_fn() as a print callback function used by btf_dump__dump_type_data(). vout() is also introduced, which is similar to out() but accepts a va_list as parameter. ss' output remains unchanged unless --bpf-maps or --bpf-map-id= is used, in which case each socket containing BPF local storage will be followed by the content of the storage before the next socket's info is displayed.

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. include/uapi
This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
