Mark __internal_statvfs[64] with attribute_hidden [BZ #18822]
Mark __internal_statvfs[64] with attribute_hidden to allow direct access

Mark 3 *_internal functions with attribute_hidden [BZ #18822]
Mark __ptsname_internal, __mktime_internal and __fopen_internal with
attribute_hidden to allow direct access to them within libc.so and
libc.a without using GOT nor PLT.
[BZ #18822]
* include/stdlib.h (__ptsname_internal): Add attribute_hidden.

Mark internal functions with attribute_hidden [BZ #18822]
Mark internal functions with attribute_hidden to allow direct access to
internal functions within libc.so and libc.a without using GOT nor PLT.
Size comparison of libc.so:
On x86-64:
text data bss dec hex
Before: 1728577 20584 17088 1766249 1af369
After : 1728593 20584 17088 1766265 1af379
The only change is __gconv_release_shlib in iconv/gconv_dl.c is inlined
since it is hidden, which increases the code size of gconv_dl.os by 18
bytes.
On i686:
text data bss dec hex
Before: 1869039 11444 11112 1891595 1cdd0b
After : 1868635 11444 11112 1891191 1cdb77
The code size is decreased by avoiding GOT/PLT for hidden functions.

string/stratcliff.c: Replace int with size_t [BZ #21982]
Fix GCC 7 errors when string/stratcliff.c is compiled with -O3:
stratcliff.c: In function ‘do_test’:
cc1: error: assuming signed overflow does not occur when assuming that (X -
c) <= X is always true [-Werror=strict-overflow]
[BZ #21982]
* string/stratcliff.c (do_test): Declare size, nchars, inner,
middle and outer with size_t instead of int. Repleace %d and
%Zd with %zu in printf.
