Introduce a general socket netlink parser which prints the header and
a string for the remaining part of the buffer. It doesn't handle all
the netlink flags and types yet because the parser needs more
information, this will be implemented later.
* net.c (decode_sockbuf): New function.
(SYS_FUNC(send), SYS_FUNC(sendto), SYS_FUNC(recv), SYS_FUNC(recvfrom)):

Assume that sysctl enums defined since linux v2.6 are always defined,
with a signle exception: check for CTL_PROC which definition was removed
in v2.6.18 and restored later in v2.6.23.

structure.

Reported-by: Dr. David Alan Gilbert <dgilbert@redhat.com>
When #val_type directive is encountered, gen.sh starts using
XLAT_TYPE/XLAT_TYPE_PAIR macros instead of XLAT/XLAT_PAIR,
with #val_type's argument as a type.
For example, "#val_type uint64_t" means values of type uint64_t.
* xlat/gen.sh (gen_header, print_xlat, print_xlat_pair):
Add val_type support.
This is essentially a no-op change that makes the following change
easier to read.
* xlat/gen.sh (print_xlat, print_xlat_pair): New functions.
(cond_xlat, gen_header): Use them.
Before this change there were two forms of xlat entries: those that use XLAT
or XLAT_END macros, and others verbatim entries. This change converts
the latter to use new XLAT_PAIR macro.
This is necessary for the upcoming change of xlat.val type.
* xlat.h (XLAT_PAIR): New macro.
* xlat/gen.sh (cond_xlat, gen_header): Use it.
* statfs.c (print_statfs_flags): New function.
(printstatfs, printstatfs64, printcompat_statfs64): Use it.
* xlat/statfs_flags.in (ST_VALID): Move to the head of the list.
* tests/statfs.expected: Update.
AF_* constants appear to be more standardized, and in practice there's
always a one to one relationship between AF_* and PF_*, so let's
use AF_* instead of PF_*.
* xlat/domains.in: Remove.
* net.c: Do not define PF_UNSPEC. Stop including "xlat/domains.h".
Replace PF_* with AF_*. Replace domains with addrfams.
* tests/inet-cmsg.c: Replace PF_INET with AF_INET.
* tests/net-yy-inet.c: Likewise.
* tests/netlink_inet_diag.c: Likewise.
* tests/net-accept-connect.c: Replace PF_LOCAL with AF_LOCAL.
* tests/net-y-unix.c: Likewise.
* tests/net-yy-unix.c: Likewise.
* tests/netlink_unix_diag.c: Likewise.
* tests/net.expected: Replace PF_ with AF_.
* xlat/clone_flags.in: Rename CLONE_STOPPED to CLONE_NEWCGROUP.
The former was removed by linux kernel commit v2.6.38-rc1~217.
The latter was introduced by linux kernel commit v4.6-rc1~67^2~8.
* xlat/bpf_map_types.in: Add BPF_MAP_TYPE_PERCPU_HASH,
BPF_MAP_TYPE_PERCPU_ARRAY, and BPF_MAP_TYPE_STACK_TRACE introduced by
linux kernel commits v4.6-rc1~91^2~326^2~5, v4.6-rc1~91^2~326^2~4, and
v4.6-rc1~91^2~212^2~1, respectively.
* xlat/if_dqinfo_flags.in: New file.
* quota.c: Include "xlat/if_dqinfo_flags.h".
(decode_cmd_data): Print struct if_dqinfo.dqi_flags using printflags.
