Fix undefined behaviour.
* lib/bitrotate.h (rotl16, rotr16, rotl8, rotr8): Case x to
'unsigned int', to avoid shift operations on 'int'.
* lib/xmemdup0.c (xmemdup0): Don't invoke memcpy with a zero size.
* tests/test-count-leading-zeros.c (main): Use a random number that has
as many bits as TYPE, not only 2*15 or 2*31 bits.
* tests/test-count-trailing-zeros.c (main): Likewise.
* tests/test-count-one-bits.c (main): Likewise.
* tests/test-memmem.c: Don't include "null-ptr.h".
(main): Use zerosize_ptr() instead of null_ptr().
* modules/memmem-tests (Files): Remove tests/null-ptr.h.

@node String Functions in C Locale @section Character and String Functions in C Locale The functions in this section are similar to the generic string functions from the standard C library, except that @itemize @item They behave as if the locale was set to the "C" locale, even when the locale is different, and/or @item They are specially optimized for the case where all characters are plain ASCII characters. @end itemize @menu * c-ctype:: * c-strcase:: * c-strcaseeq:: * c-strcasestr:: * c-strstr:: * c-strtod:: * c-strtold:: @end menu @node c-ctype @subsection c-ctype @include c-ctype.texi @node c-strcase @subsection c-strcase @include c-strcase.texi @node c-strcaseeq @subsection c-strcaseeq @include c-strcaseeq.texi @node c-strcasestr @subsection c-strcasestr @include c-strcasestr.texi @node c-strstr @subsection c-strstr @include c-strstr.texi @node c-strtod @subsection c-strtod @include c-strtod.texi @node c-strtold @subsection c-strtold @include c-strtold.texi
