d915a14ef0 libc: further adoption of SPDX licensing ID tags.
Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

cc4c35b961 Teach fmtcheck() about wint_t, intmax_t, char *, intmax_t *, and
wide string arguments.

Also simplify the code that handles length modifiers and make it
more conservative. For instance, be explicit about the modifiers
allowed for %d, rather than assuming that anything other than L,
q, t, or z implies an int argument.

38d17374b2 When *printf() and *scanf() are compiled without floating-point
support, fmtcheck() should not accept format strings that contain
floating-point formats.

3d09054934 Add fmtcheck(), a function for checking consistency of format string
arguments where the format string is obtained from user data, or
otherwise difficult to verify statically.

Example usage:

printf(fmtcheck(user_format, standard_format), arg1, arg2);

checks the format string user_format for consistency (same number/order/
type of format operators) with standard_format.  If they differ,
standard_format is used instead to avoid potential crashes or security
violations.
