Add __vsyslog_internal, with same flags as __v*printf_internal. __nldbl___vsyslog_chk will ultimately want to pass PRINTF_LDBL_IS_DBL down to __vfprintf_internal *as well as* possibly setting PRINTF_FORTIFY. To make that possible, we need a __vsyslog_internal that takes the same flags as printf. The code in misc/syslog.c does also get a little simpler. Tested for powerpc and powerpc64le.

ldbl-128ibm-compat: PLT redirects for using ldbl redirects internally Tweak the PLT bypass magic when building glibc with long double redirects. This is made more difficult by the fact we only get one chance to redirect functions. This happens via the public headers. There are roughly three classes of redirect we need to attend to today: 1. Simple redirects, redirected via cdef macro overrides and and new libc_hidden_ldbl_proto macro. 2. Internal usage of internal API, e.g __snprintf, which has no direct analogue. This is bypassed directly on case-by- case basis. 3. Double redirects, e.g sscanf and related. These require a heavier handed approach of macro renaming to existing symbols. Most simple redirects are handled via 1. Ideally, the libc_* macro would live in libc-symbols.h, but in practice the macros needed for it to do anything useful live in cdefs.h, so they are defined in the local override. Notably, the internal name of the asprintf generated for ieee ldbl redirects is renamed to work with internal prefixed usage. This resolves the local plt usage introduced when building glibc with ldbl == ieee128 on ppc64le. Reviewed-by: Tulio Magno Quites Machado Filho <tuliom@linux.ibm.com>

libc_hidden_ldbl_proto (syslog)
* misc/bits/syslog.h: New file. * misc/sys/syslog.h: Include <bits/syslog.h> for fortification. * misc/Makefile (headers): Add bits/syslog.h. * include/sys/syslog.h: Add __vsyslog_chk prototype and hidden_proto. * sysdeps/generic/syslog.c: Change vsyslog function to __vsyslog_chk. Call __vfprintf_chk if necessary. Make vsyslog a wrapper. Add __syslog_chk. * misc/Versions: Export __syslog_chk and __vsyslog_chk. * nis/nis_xdr.c: Help gcc to avoid generating unnecessary wrapper functions.
