5d39f37b26 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 5a82c74822.  This trivial patch fixes this issue.

c2f959ed5f ldbl-128ibm-compat: Test positional arguments
The format string can request positional parameters, instead of relying
on the order in which they appear as arguments.  Since this has an
effect on how the type of each argument is determined, this patch
extends the test cases to use positional parameters with mixed double
and long double types, to verify that the IEEE long double
implementations of *printf work correctly in this scenario.

Tested for powerpc64le.

5bbbd5ae05 ldbl-128ibm-compat: Test double values
A single format string can take double and long double parameters at the
same time.  Internally, these parameters are routed to the same
function, which correctly reads them and calls the underlying functions
responsible for the actual conversion to string.  This patch adds a new
case to test this scenario.

Tested for powerpc64le.

1771a5cf0e ldbl-128ibm-compat: Add wide character printing functions
Similarly to what was done for regular character printing functions,
this patch uses the new mode mask, PRINTF_LDBL_USES_FLOAT128, in the
'mode' argument of the wide characters printing function,
__vfwprintf_internal (which is also extended to support printing
floating-point values with IEEE binary128, by saving floating-point
values into variables of type __float128 and adjusting the parameters to
__printf_fp and __printf_fphex as if it was a call from a wide-character
version of strfromf128 (even though such version does not exist)).

Tested for powerpc64le.
