Change the Makefile and build process to no longer require audit-libs
interfaces when the architecture provides system call tables.
Committer notes:
Its not enough to hook into the NO_LIBAUDIT makefile block, we need to
define a CONFIG_TRACE that gets selected by both architectures
generating the syscall tables from the kernel headers and from detecting
the availability of libaudit.
With that in place we will not link against libaudit even if the
necessary files are available for that, in fact we will not even try to
detect its availability, speeding up a bit the feature detection phase.

Replace the errno_to_name() from the audit-libs with the newly
introduced arch_syscalls__strerrno() function.
With this change:
1. With replacing errno_to_name() from audit-libs, perf trace
does no longer require audit-lib interfaces.
2. In addition to 1, the audit-libs dependency can be removed
for architectures that support syscall tables in perf.
This is achieved in a follow-up commit.
3. With the architecture specific errno number/name mapping,
perf trace reports can work across architectures.

Introduce a script that generates a mapping of errno numbers to their
names for each architecture that is supported by perf (i.e. has a
subdirectory in tools/perf/arch/).
The errno mapping is generated as part of the trace beautifiers and can
be used by including the trace/beauty/arch_errno_names.c file. Then,
use arch_syscalls__strerrno() to look up an errno value to obtain the
errno name (e.g. ENOENT) for a particular architecture.

I've meet a strange behavior with these commands on my gentoo box:
1: perf kmem record
2: CTRL-C to stop 1
3: perf report
4: "Enter", "Enter", "Run scripts for all samples",
"event_analyzing_sample".
Then 'perf report' says:
"
No kallsyms or vmlinux with build-id xxxx was found
/lib/modules/4.10.0+/build/vmlinux with build id xxxx not found,
continuing without symbols
".
It is strange because I am sure /lib/modules/4.10.0+/build/vmlinux is
right for perf.data.
After digging, I found out the reason is that "perf report" generates
many open fds, then "script_browse" uses popen to run "perf script"
which run out of open files.
The gentoo box has a small default value for "max open files", 1024.
Yes, "ulimit -n " with a bigger number could fix it, but I think that
using O_CLOEXEC in do_open is a better way.

It isn't needed at all in these files, dynamic debug is the best way to
enable this type of thing, if you really want it. As it is, these
defines were not doing anything at all.

Move the license "mark" of the sysfs files to be in SPDX form, instead
of the custom text that it currently is in. This is in a quest to get
rid of the 700+ different ways we say "GPLv2" in the kernel tree.

This adds the coredump driver operation. When the driver defines it
a coredump file is added in the sysfs folder of the device upon
driver binding. The file is removed when the driver is unbound.
User-space can trigger a coredump for this device by echo'ing to
the coredump file.

This patch adds the specification for /sysfs/devices/.../coredump
which allows user-space to trigger a device coredump obtaining
binary data from the device for (fault) analysis. It relies on
CONFIG_DEV_COREDUMP being enabled.
