Hide __readv and __writev [BZ #18822]
Hide internal __readv and __writev functions to allow direct access within libc.so and libc.a without using GOT nor PLT. [BZ #18822] * include/sys/uio.h (__readv): Add libc_hidden_proto. (__writev): Likewise. * misc/readv.c (__readv): Add libc_hidden_def. * misc/writev.c (__writev): Likewise. * sysdeps/posix/readv.c (__readv): Likewise. * sysdeps/posix/writev.c (__writev): Likewise. * sysdeps/unix/sysv/linux/readv.c: Include <sys/uio.h>. (__readv): Likewise. * sysdeps/unix/sysv/linux/writev.c: Include <sys/uio.h>. (__writev): Likewise.
