This allows testing of MPERS_IS_* macros in pre-MPERS_DEFS parts
of source code.
* Makefile.am (mpers-m%.stamp): Add -DMPERS_IS_$(mpers_NAME) to CFLAGS
passed to mpers.sh.
* mpers_test.sh: Likewise.
For the reason described in commit v4.10-517-gcfde1e3, a correct
definition of struct stat for x32 personality is necessary to enable
"asm_stat.h" with -mx32 on x86_64.
* linux/x32/asm_stat.h: Rename to ...
* linux/x86_64/asm_stat.h: ... new file.

[SPARC64]: Likewise, for the native personality.
Save ipc cubcall version for later use by specific ipc parsers.

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)):

(block_ioctl): Move parser of HDIO_GETGEO to hdio.c.
* defs.h (hdio_ioctl): New prototype.
* ioctl.c (ioctl_decode): Call hdio_ioctl for ioctl type 0x03.
We used to declare and define all printers marked with
MPERS_PRINTER_DECL, including ifdef'ed ones. That approach left us
no way to conditionally compile mpersified printers, which was not
a problem until btrfs ioctls appeared on the horizon.
With this change, those mpersified printers that are not going
to be compiled are also won't be declared and won't be added to
struct_printers.
This is implemented by filtering all source files containing
MPERS_PRINTER_DECL markers through CPP. As a nice side effect, this
also lifts an ugly requirement of writing all MPERS_PRINTER_DECL
declarations in a single line.
* README-mpers: Update description of MPERS_PRINTER_DECL syntax.
* defs.h [IN_MPERS_BOOTSTRAP] (MPERS_PRINTER_DECL): Turn into
a recursive variadic macro.

mpers_preproc_files instead of srcdir_mpers_source_files,
use mpers_printer_decl_pattern.
* .gitignore: Add /*.mpers.i.
* linux/netlink_diag.h: New file.
* Makefile.am (EXTRA_DIST): Add it.
* socketutils.c: Include it and "xlat/netlink_protocols.h".

(CODE_COVERAGE_GENHTML_OPTIONS): Update, add prefix.
(CODE_COVERAGE_BRANCH_COVERAGE): Set to 1.
As values of some ioctl macros differ between personalities, these
personality specific ioctl macros should be properly defined for
mpersified code. Implement this by redefining personality specific
ioctl macros from ioctlent*.h for each file that includes MPERS_DEFS.
* Makefile.am (ioctl_macros_h): New variable.
(ioctl_macros%.h): New rule.
(BUILT_SOURCES, CLEANFILES): Add $(ioctl_macros_h).

Define struct xlat in a separate file so that it could be used later by
tests without inclusion of defs.h header file.
* defs.h (struct xlat, XLAT, XLAT_END): Move ...
* xlat.h: ... here.
* Makefile.am (strace_SOURCES): Add xlat.h.
For each given architecture only one of these two syscalls has a
syscallent entry. When each parser is placed into a separate file,
moving to libstrace ensures that only one of them that is need
is linked into strace executable.
* sync_file_range.c (SYS_FUNC(sync_file_range2)): Move ...
* sync_file_range2.c: ... here.
* Makefile.am (strace_SOURCES): Move sync_file_range.c ...
(libstrace_a_SOURCES): ... here. Add sync_file_range2.c.
(strace_SOURCES_c): Add filtered libstrace_a_SOURCES.
Some files are used conditionally depending on architecture and
configuration. Create a library for the purpose of keeping such
compilation units.
* Makefile.am (strace_LDADD, noinst_LIBRARIES): Add libstrace.a.
(libstrace_a_CPPFLAGS): New variable, set to $(strace_CPPFLAGS).
(libstrace_a_CFLAGS): New variable, set to $(strace_CFLAGS).

(libmpers_CFLAGS): New variable, set to $(strace_CFLAGS).
(libmpers_m32_a_CFLAGS, libmpers_mx32_a_CFLAGS): New variables,
set to $(libmpers_CFLAGS).
Do not rely on "struct sigevent.__pad" being located at the same address
as "struct sigevent.sigev_notify_thread_id", it's not the case with musl
libc. Do not rely on struct sigevent definition at all to access
sigev_notify_thread_id.
* configure.ac (AC_CHECK_MEMBERS): Remove struct sigevent._sigev_un._pad
and struct sigevent.__pad.
* sigevent.h: New file.

* print_sigevent.c: Include it.
* print_sigevent.c (struct_sigevent): Remove.
(print_sigevent): Update all struct_sigevent users.
* tests/timer_create.c: Include "sigevent.h".
(main): Use struct_sigevent instead of struct sigevent,
all struct sigevent clients changed.
Print the second return value of getxpid, getxuid, and getxgid syscalls
that return a pair of values using the same mechanism as pipe syscall.
* alpha.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* linux/alpha/syscallent.h [20]: Change SEN(getpid) to SEN(getxpid).
[24]: Change SEN(getuid) to SEN(getxuid).
[47]: Change SEN(getgid) to SEN(getxgid).

(TESTS): Add getxxid.test.
* tests/.gitignore: Add getxxid.
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.
As tests-m*32/Makefile.am files now refer to proper arch specific
directories, it's possible to relocate x32 <asm/stat.h> replacement
to its arch specific directory.
* linux/x86_64/asm_stat.h: Move ...
* linux/x32/asm_stat.h: ... here, remove x32 guard.
* Makefile.am (strace_SOURCES): Remove linux/x86_64/asm_stat.h.
Some old kernel headers, Ubuntu 14.04 in particular, provide
<asm/stat.h> editions that are completely wrong for x32.
Workaround this issue by providing a replacement.
* linux/x86_64/asm_stat.h: New file.
* linux/x32/asm_stat.h: Likewise.
* Makefile.am (strace_SOURCES): Add them.
Apparently, there are only two types of instruction pointer printers
depending on the architecture: those that print a register that was
fetched earlier, and those that fetch a register themselves using upeek.
With this change, architectures of the first type have ARCH_PC_REG
defined in their arch_regs.c file, architectures of the first type
have ARCH_PC_PEEK_ADDR defined there, and the common code in syscall.c
uses these macros to print the instruction pointer.
