82f43dd2d1 Include shlib-compat.h in many sunrpc/nis source files.
Every file that uses libc_hidden_nolink_sunrpc or
libnsl_hidden_nolink_def needs to include shlib-compat.h.  Currently,
most of them are getting it via stdio.h, because libio.h refers to
SHLIB_COMPAT when _LIBC is defined, so it includes shlib-compat.h.  My
experimental patch to not install libio.h breaks that chain; stdio.h
no longer pulls in libio.h even for internal users.

Accordingly, this patch adds #include <shlib-compat.h> to many files
in sunrpc/ and nis/.  There are also a small number of really obvious
fixups to includes that caught my eye while proofreading the patch -
not including headers twice in a row, not worrying about portability
to Ultrix anymore, sort of thing.

a992f506ff Remove __need macros from signal.h.
The types affected are __sig_atomic_t, sig_atomic_t, __sigset_t,
sigset_t, sigval_t, sigevent_t, and siginfo_t. __sig_atomic_t is a
scalar, so it's now directly available from bits/types.h.  The others
get bits/types/ headers.

Side effects include: There have been small changes to which
non-signal headers expose which subset of the signal-related types.
A couple of architectures' nested siginfo_t fields had to be renamed
to prevent undesired macro expansion.  Internal code that wants to
manipulate signal masks must now include <sigsetops.h> (which is not
installed) and should be aware that __sigaddset, __sigandset,
__sigdelset, __sigemptyset, and __sigorset no longer return a value
(unlike the public API).  Relatedly, the public signal.h no longer
declares any of those functions.  The obsolete sigmask() macro no
longer has a system-specific definition -- in the cases where it
matters, it didn't work anyway.

New Linux architectures should create bits/siginfo-arch.h and/or
bits/siginfo-consts-arch.h to customize their siginfo_t, rather than
duplicating everything in bits/siginfo.h (which no longer exists).
Add new __SI_* macros if necessary.  Ports to other operating systems
are strongly encouraged to generalize this scheme further.

500b3a499f Remove __need_list_t and __need_res_state.
These __need macros are only used internally, by nptl/descr.h.
However, including all of resolv.h from descr.h causes build failures
due to resolv.h's dozens of pseudo-struct-field macros, some of which
collide with struct fields in NPTL internal data structures.
Similarly, including all of list.h from descr.h produces an include
cycle, atomic.h -> atomic-machine.h -> tls.h -> descr.h -> list.h ->
atomic.h, and then list.h tries to use atomic.h macros that haven't
been defined yet.  So we do need mini-headers for these.  In the
list.h case I called it include/list_t.h since it isn't going to be
installed.

8ec69bb7ec support_format_addrinfo: Fix flags and canonname formatting
The address family splitting via format_ai_family made unpredictable
the place where the canonname field was printed.  This commit adjusts
the implementation so that the ai_flags is checked for consistency
across the list, and ai_canonname must only be present on the first
list element.

Tests for AI_CANONNAME are added to resolv/tst-resolv-basic.

176804300b Fix network headers stdint.h namespace (bug 21455).
conform/ namespace tests of arpa/inet.h, netdb.h and netinet/in.h fail
for UNIX98 and XPG42 because of inclusion of stdint.h, which defines
macros not permitted in those headers for those standards.  UNIX98
allows them to include inttypes.h, but (predating C99) has restricted
inttypes.h contents (not yet tested in the conform/ tests) not
including those macros; XPG4.2 has no such permission and no
inttypes.h / stdint.h at all.

This patch rearranges the headers to avoid this issue.  intN_t
definitions move to bits/stdint-intn.h, and uintN_t definitions to
bits/stdint-uintn.h.  (These are not bits/types/ headers because they
each define four types.  They are separate rather than just a single
header because sys/types.h defines intN_t but u_intN_t rather than
uintN_t - and while sys/types.h could define uintN_t because of the
POSIX reservation of *_t, existing practice there is largely to
condition types on appropriate feature test macros, and indeed there
is at least one open bug report (14553) about a type that's not
so-conditioned, so maybe types there should actually have conditions
added where appropriate.)  The affected network headers are then made
to include bits/stdint-uintn.h instead of stdint.h.  This allows six
XFAILs to be removed.

This doesn't do anything about inttypes.h defining more than it should
for UNIX98, but we don't have conformtest expectations for that case
at present (and my inclination is that a fix for that should be as
local as possible - affecting only inttypes.h, not stdint.h, only for
the case of __USE_UNIX98 && !__USE_ISOC99).

Tested for x86_64.

9090848d06 Narrowing the visibility of libc-internal.h even further.
posix/wordexp-test.c used libc-internal.h for PTR_ALIGN_DOWN; similar
to what was done with libc-diag.h, I have split the definitions of
cast_to_integer, ALIGN_UP, ALIGN_DOWN, PTR_ALIGN_UP, and PTR_ALIGN_DOWN
to a new header, libc-pointer-arith.h.

It then occurred to me that the remaining declarations in libc-internal.h
are mostly to do with early initialization, and probably most of the
files including it, even in the core code, don't need it anymore.  Indeed,
only 19 files actually need what remains of libc-internal.h.  23 others
need libc-diag.h instead, and 12 need libc-pointer-arith.h instead.
No file needs more than one of them, and 16 don't need any of them!

So, with this patch, libc-internal.h stops including libc-diag.h as
well as losing the pointer arithmetic macros, and all including files
are adjusted.

d4f94368a9 Get rid of duplicate const declaration specifier warning in tst-resolv-qtypes.c.
Compiling resolv/tst-resolv-qtypes.c with GCC 7 results in:
tst-resolv-qtypes.c:53:14: error: duplicate ‘const’ declaration specifier [-Werror=duplicate-decl-specifier]
 static const const char *domain = "www.example.com";

This patch removes the duplicate const and makes domain a const pointer
to const char literal.

ChangeLog:

	* resolv/tst-resolv-qtypes.c (domain):
	Change type to const pointer to const char.

e7eceec0bc resolv: Turn historic name lookup functions into compat symbols
This change also removes the preprocessor-based function renaming.
It also applied to tests in resolv/, which ended up running against
the historic functions.

_endhtent was not part of the ABI because it is not listed in the
resolv/Versions file.

0cb9dcc8f2 Bug 20729: Fix build failures on ppc64 and other arches.
The changes to fix bug 20729 introduced an error which removed an
ignore diagnostic from -O2 by using the new -Os related macro.
This broke ppc64 builds. This commit fixes the mistake.

Tested on x86, x86_64, ppc64, ppc64le, arm, aarch64, and s390x.

93fe09cb5f Bug 20729: Fix building with -Os.
This commit adds a new DIAG_IGNORE_Os_NEEDS_COMMENT which is only
enabled when compiling with -Os. This allows developers working on
-Os enabled builds to mark false-positive warnings without impacting the
warnings emitted at -O2.

Then using the new DIAG_IGNORE_Os_NEEDS_COMMENT we fix 6 warnings
generated with GCC 5 to get -Os builds working again.
