Add a macro for printing fields explicitly casted to specific type.
This is useful for bit fields, as otherwise the magic of *_extend_to_*
macros breaks.
* print_field.h (PRINT_FIELD_U_CAST): New macro.
As uid is not the only thing that has a special treatment of the -1
value (and, as a result, needs special care), let's rename
PRINT_FIELD_UID to PRINT_FIELD_ID and make PRINT_FIELD_UID its alias.
* print_fields.h (PRINT_FIELD_ID): Rename from PRINT_FIELD_UID.
(PRINT_FIELD_UID): Define to PRINT_FIELD_ID.
* print_fields.h (PRINT_FIELD_STR, PRINT_FIELD_PATH): New macros.
* bpf.c: Include "print_fields.h".
(bpf_map_create): Use PRINT_FIELD_U and PRINT_FIELD_XVAL.
(bpf_map_update_elem): Use PRINT_FIELD_FD, PRINT_FIELD_X, and
PRINT_FIELD_XVAL.
(bpf_map_delete_elem, bpf_map_io): Use PRINT_FIELD_FD and PRINT_FIELD_X.
(bpf_prog_load): Use PRINT_FIELD_STR, PRINT_FIELD_U, PRINT_FIELD_X,
and PRINT_FIELD_XVAL.
(bpf_obj_manage): Use PRINT_FIELD_FD and PRINT_FIELD_PATH.
(bpf_prog_attach_detach): Use PRINT_FIELD_FD, PRINT_FIELD_FLAGS,
and PRINT_FIELD_XVAL.
In many places where kernel expects a NUL-terminated string of length
up to a known fixed limit, e.g. when a NUL-terminated string is
a fixed-size field of a structure, strace does not print the last byte
assuming it is NUL, which is not always the case.
Change output format for such strings to distinguish NUL-terminated
strings from non-NUL-terminated ones: append ellipsis to the output
when the string is not NUL-terminated.
* defs.h (print_quoted_cstring): New prototype.
* util.c (print_quoted_cstring): New function.
(printpathn): Use it instead of print_quoted_string with
QUOTE_0_TERMINATED argument.
* print_fields.h (PRINT_FIELD_CSTRING): Likewise.
* btrfs.c (btrfs_ioctl): Likewise.
* dirent.c (SYS_FUNC(getdents)): Likewise.
* dirent64.c (SYS_FUNC(getdents64)): Likewise.
* print_ifindex.c (print_ifindex): Likewise.
* sysmips.c (SYS_FUNC(sysmips)): Likewise.
* ubi.c (ubi_ioctl): Likewise.
* tests/tests.h (print_quoted_cstring): New prototype.
* tests/print_quoted_string.c (print_quoted_cstring): New function.
* tests/ioctl_block.c (main): Update expected output.
* tests/ioctl_dm.c (main): Likewise.
* tests/ioctl_loop.c (print_loop_info, print_loop_info64): Likewise.
* tests/netlink_crypto.c (test_crypto_msg_newalg): Likewise.
As string fields are always qouted when printed, choose a shorter name
for the helper macro.
* print_fields.h (PRINT_FIELD_QUOTED_STRING): Rename
to PRINT_FIELD_STRING. All callers updated.
* print_fields.h (PRINT_FIELD_0X): New macro.
* sockaddr.c (print_sockaddr_data_ipx, print_sockaddr_data_nl): Use it
instead of manual tprintf statements.

* net.c (print_group_req): Likewise.
* sock.c (PRINT_IFREQ_ADDR): Remove.
(print_ifreq, print_ifconf_ifreq): Use PRINT_FIELD_SOCKADDR
instead of PRINT_IFREQ_ADDR.
