commit 7292a51cb0aed8a9c1da5cc9b7f16ea1f11584c2
Author: Zack Weinberg <zackw@panix.com>

Convert signal.h from __need macros to bits/types/ headers.
This was considerably hairier than any of the preceding conversions,
because sigset_t is OS-dependent, and siginfo_t and sigevent_t are
both OS- and machine-dependent. And the bits headers that defined
them also defined a whole bunch of other stuff that was mostly _not_
OS- or machine-dependent. I have disentangled it as much as I think
is feasible short of going to generated 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 (you know the thing where a perfectly
ordinary user-namespace identifier is defined as a macro expanding
to a chain of nested structure references? that thing is terrible).
Internal code that wants to manipulate signal masks must now include
<bits/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, which returns 'int' solely
so that it can return -1 instead of crashing when given null pointers).
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; I might do
a follow-on patch that unifies the Linux-generic bits headers with the
totally generic ones.
It might make sense to make bits/sigsetops.h into a new, public set of
inline functions (like the existing bits/string2.h) but it seems
unlikely that signal mask manipulation is performance-critical to
anyone, so I'm not inclined to bother.

commit 897982b94fa6fefb6fa68edbfc31c648b50afb68
Author: Zack Weinberg <zackw@panix.com>
Date: Sun Nov 20 23:00:02 2016 -0500
The bits/types/*.h treatment for stdio and wchar.
wint_t is a little finicky because it might be defined by stddef.h, which
belongs to the compiler.
In addition to the _types_, a bunch of other declarations shared between
wctype.h and wchar.h are factored out to their own header.
* libio/bits/types/FILE.h, libio/bits/types/__FILE.h
* wcsmbs/bits/types/mbstate_t.h, wcsmbs/bits/types/__mbstate_t.h
* wcsmbs/bits/types/wint_t.h: New single-type definition files.
* wctype/bits/wctype-wchar.h: New file holding declarations shared
between wctype.h and wchar.h.
* libio/Makefile, wcsmbs/Makefile, wctype/Makefile:
Install them.
* include/bits/types/FILE.h, include/bits/types/__FILE.h
* include/bits/types/mbstate_t.h, include/bits/types/__mbstate_t.h
* include/bits/types/wint_t.h, include/bits/wcsmbs-wchar.h:
New wrappers.
* include/stdio.h, include/wchar.h, include/wctype.h:
No need to handle __need macros.
* grp/grp.h, gshadow/gshadow.h, hurd/hurd.h, iconv/gconv.h
* libio/stdio.h, mach/mach.h, misc/mntent.h, pwd/pwd.h
* shadow/shadow.h, stdio-common/printf.h, wcsmbs/uchar.h
* wcsmbs/wchar.h, wctype/wctype.h
* sysdeps/generic/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h
Use the new files instead of __need macros.
