ldbl-128ibm-compat: Add regular character scanning functions The 'mode' argument to __vfscanf_internal allows the selection of the long double format for all long double arguments requested by the format string. Currently, there are two possibilities: long double with the same format as double or long double as something else. The 'something else' format varies between architectures, and on powerpc64le, it means IBM Extended Precision format. In preparation for the third option of long double format on powerpc64le, this patch uses the new mode mask, SCANF_LDBL_USES_FLOAT128, which tells __vfscanf_internal to call __strtof128_internal, instead of __strtold_internal, and save the output into a _Float128 variable. Tested for powerpc64le. Reviewed-By: Paul E. Murphy <murphyp@linux.ibm.com>

/* Wrapper for vscanf. 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 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 ... remote: *** error: lines with trailing whitespace found remote: error: hook declined to update refs/heads/master

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.
