The printf tests have no coverage for long double. Duplicate the
double tests so that we have some basic coverage.

I used these shell commands:
../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright
(cd ../glibc && git commit -am"[this commit message]")
and then ignored the output, which consisted lines saying "FOO: warning:
copyright statement not found" for each of 6694 files FOO.
I then removed trailing white space from benchtests/bench-pthread-locks.c
and iconvdata/tst-iconv-big5-hkscs-to-2ucs4.c, to work around this
diagnostic from Savannah:
remote: *** pre-commit check failed ...

Recent GCC -Wformat-overflow= changes result in some printf tests
failing to build, because those tests are deliberately testing the
handling of formats writing more than INT_MAX characters and the
handling of NULL arguments to the %s format, which GCC now warns
about. This patch duly disables -Wformat-overflow= for the relevant
calls to printf functions.
Tested with build-many-glibcs.py with GCC mainline for
aarch64-linux-gnu.
* stdio-common/bug22.c: Include <libc-diag.h>.
(do_test): Disable -Wformat-overflow= warnings around fprintf
calls outputting more than INT_MAX characters.
* stdio-common/tst-printf.c: Disable -Wformat-overflow= warnings
around printf call with NULL %s argument.
Fix the ifdef clause that was being used in the opposite way, setting
a wrong value of the carry bit.
This is also correcting 2 memory accesses that were mistakenly referring
to r0 while they were supposed to mean the immediate value 0.
[BZ #22142]
* stdio-common/tst-printf.c (fp_test): Add tests for DBL_MAX and
-DBL_MAX.
(do_test): Likewise.
* stdio-common/tst-printf.sh: Likewise.
* sysdeps/powerpc/powerpc64/power7/add_n.S: Invert the initial
ifdef clause in order to set the carry bit right. Replace r0 by
0 without changing the behavior.
Quite a few tests include libc-internal.h just for the DIAG_* macros.
Split those macros to their own file, which can be included safely in
_ISOMAC mode. I also moved ignore_value, since it seems logically
related, even though I didn't notice any tests needing it.
Also add -Wnonnull suppressions to two tests that _should_ have them,
but the error is masked when compiling against internal headers.
* include/libc-diag.h: New file. Define ignore_value,
DIAG_PUSH_NEEDS_COMMENT, DIAG_POP_NEEDS_COMMENT,
DIAG_IGNORE_NEEDS_COMMENT, and DIAG_IGNORE_Os_NEEDS_COMMENT here.
* include/libc-internal.h: Definitions of above macros moved from
here. Include libc-diag.h. Add copyright notice.
* malloc/tst-malloc.c, malloc/tst-memcheck.c, malloc/tst-realloc.c
* misc/tst-error1.c, posix/tst-dir.c, stdio-common/bug21.c

* stdlib/bug-getcontext.c, string/tester.c, string/tst-endian.c
* time/tst-strptime2.c, wcsmbs/tst-wcstof.c:

* stdlib/tst-environ.c: Include libc-diag.h. Suppress -Wnonnull for
call to unsetenv (NULL).
* nptl/tst-mutex1.c: Include libc-diag.h. Suppress -Wnonnull for
call to pthread_mutexattr_destroy (NULL).
This patch fixes the glibc testsuite build for GCC 7
-Wformat-truncation, newly moved out of -Wformat-length and with some
further warnings that didn't previously appear. Two tests that
previously disabled -Wformat-length are changed to disable
-Wformat-truncation instead; two others are made to disable that
option as well.
Tested (compilation only) with build-many-glibcs.py for aarch64 with
GCC mainline.
* stdio-common/tst-printf.c [__GNUC_PREREQ (7, 0)]: Ignore
-Wformat-truncation instead of -Wformat-length.
* time/tst-strptime2.c (mkbuf) [__GNUC_PREREQ (7, 0)]: Likewise.
* stdio-common/tstdiomisc.c (F): Ignore -Wformat-truncation for
GCC 7.
* wcsmbs/tst-wcstof.c: Include <libc-internal.h>.
(do_test): Ignore -Wformat-truncation for GCC 7.
These tests were skipped by the use-test-skeleton conversion done in
commit 29955b5d because they did not have an `int main (void)'
declaration. Instead their `main' functions were declared with arguments
(i.e. argc, argv) even though they didn't use them.
Remove these arguments and include the test skeleton in these tests.

short and byte values from parameter list.
