ldbl-128ibm-compat: Add wide character, fortified printing functions Similarly to what was done for the regular character, fortified printing functions, this patch combines the mode masks PRINTF_LDBL_USES_FLOAT128 and PRINTF_FORTIFY to provide wide character versions of fortified printf functions. It also adds two flavors of test cases: one that explicitly calls the fortified functions, and another that reuses the non-fortified test, but defining _FORTIFY_SOURCE as 2. The first guarantees that the implementations are actually being tested (independently of what's in bits/wchar2.h), whereas the second guarantees that the redirections calls the correct function in the IBM and IEEE long double cases. Tested for powerpc64le. Reviewed-By: Paul E. Murphy <murphyp@linux.ibm.com>

/* Wrapper for __vswprintf_chk. IEEE128 version.
Update copyright dates with scripts/update-copyrights 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 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

ldbl-128ibm-compat: Replace http with https in new files Several commits to the ldbl-128ibm-compat directory added new files where the URL in the copyright notice pointed to an http, rather than to an https, address. This happened because I copied the notices before commit ID 5a82c74822d3. This trivial patch fixes this issue.
