Fix -Os getc_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 getc_unlocked. __getc_unlocked already exists; this patch makes it explicitly hidden, calls it where needed for namespace reasons, adds an inline function for it when inline functions are used and adds libc_hidden_proto / libc_hidden_weak for getc_unlocked. 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/getc_u.c (getc_unlocked): Use libc_hidden_weak. * include/stdio.h [!_ISOMAC] (__getc_unlocked): Use attribute_hidden, and define inline if [__USE_EXTERN_INLINES]. [!_ISOMAC] (getc_unlocked): Use libc_hidden_proto. * misc/getttyent.c (__getttyent): Call __getc_unlocked instead of getc_unlocked. * time/tzfile.c (__tzfile_read): Likewise.
