Fix -Os ferror_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with
-Os that arise from functions not being inlined in that case, this
patch fixes such failures for ferror_unlocked.
The usual approach is followed of adding __ferror_unlocked (inlined
when ferror_unlocked is), making calls use it when required for
namespace reasons (only one such call), and using libc_hidden_proto /
libc_hidden_weak for the ferror_unlocked weak alias when only localplt
but not namespace issues are involved.
Tested for x86_64 (both without -Os to make sure that case continues
to work, and with -Os to make sure all the relevant linknamespace and
localplt test failures are resolved). Because of other such failures
that remain after this patch, neither of the bugs can yet be closed.
[BZ #15105]
[BZ #19463]
* libio/ferror_u.c (ferror_unlocked): Rename to __ferror_unlocked
and define as weak alias of __ferror_unlocked. Use
libc_hidden_weak.
* include/stdio.h [!_ISOMAC] (ferror_unlocked): Use
libc_hidden_proto.
[!_ISOMAC] (__ferror_unlocked) New declaration, and inline
function if [__USE_EXTERN_INLINES].
* time/getdate.c (__getdate_r): Call __ferror_unlocked instead of
ferror_unlocked.
