a0bd3749fc Declare syscall parsers using SYS_FUNC macro 
Introduce SYS_FUNC macro to declare and define all syscall parsers.

* Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h.
(sys_func.h): New rule.
* defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros.
* linux/syscall.h: Include "sys_func.h".
[NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers.
Remove other declarations.
* linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs
and osf_fstatfs syscall parsers.

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.

* xlat/capabilities1.in: New file.
* 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.
* tests/Makefile.am (CHECK_PROGRAMS): Add caps.
(TESTS): Add caps.test.
(EXTRA_DIST): Add caps.awk.

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.
