38a34c9349 Add copyright headers to some files which lack them
Before this change, all files that exist since 20th century had
copyright headers, while most files that appeared later didn't.  This
change fixes the inconsistency by adding missing copyright headers.

It doesn't mean that copyright headers became maintained.  In my view,
git history provides much better information on this subject and is much
more accurate than copyright headers.

4b9c68b9a3 Implement full decoding of 64-bit capabilities
Unlike v1 capabilities which are 32-bit, v2 and v3 are 64-bit, but
before this change only lower 32 capability bits were decoded for
v2 and v3.

* capability.c: Define v2/v3 CAP_* constants.
Include xlat/capabilities1.h.
(get_cap_header): New function.
(print_cap_header): Update to use get_cap_header result.
(print_cap_data): Decoder higher capability bits for v2 and v3.
(sys_capget, sys_capset): Use get_cap_header, update print_cap_header
and print_cap_data calls.
* tests/caps.c: New file.
* tests/caps.awk: New file.
* tests/caps.test: New test.

bf7fdfa96e Make parsers of capget and capset syscalls self-contained
Various versions of <linux/capability.h> used to require different
workarounds to avoid conflicts with types defined by libc headers.
Define all required types and constants locally to fix this issue.

* configure.ac (AC_CHECK_HEADERS): Remove linux/capability.h.
* capability.c: Do not include <linux/capability.h>, remove workarounds
for problematic versions of <linux/capability.h> file.
Define CAP_* and _LINUX_CAPABILITY_VERSION_* constants as enums.
(struct __user_cap_header_struct, struct __user_cap_data_struct): Define.
* xlat/cap_version.in: Add #unconditional.
* xlat/capabilities.in: Likewise.

5e7987b4a8 Move capget and capset parsers to a separate file
* capability.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* system.c: Move inclusion of headers and macro definitions related
to capget and capset decoding to capability.c.
(print_cap_header, print_cap_data, sys_capget, sys_capset): Move
to capability.c.
