uchar.h: New header file for C11 (and C++11) compliance.

Implementation of the new functions mbrtoc16, c16rtomb, mbrtoc32, and

PR lib/52374: <uchar.h> missing

libc: New C11 functions mbrtoc16, mbrtoc32, c16rtomb, c32rtomb.

The mbrtoc16/32 functions read mulitbyte strings according to the
current locale into UTF-16/32 code unit sequences; the c16/32rtomb
functions write UTF-16/32 code unit sequences into multibyte strings
according to the current locale.  The `r' means restartable: they
work incrementally and pick up where they left off.

NOTE: This bumps the libc minor version, since it adds new symbols.

libc: New functions c8rtomb(3) and mbrtoc8(3).

New in C23, for converting from UTF-8 to locale-dependent multibyte

char8_t.

- _NETBSD_SOURCE

likely cause more trouble if pulled up) because some definitions of
__CTASSERT make a declaration which is forbidden after a label, so

PR lib/58612: c8rtomb/c16rtomb/c32rtomb yield suboptimal shift

c32rtomb(3): Use conversion state to handle shift sequences.
For conversion of Unicode scalar values to coding systems requiring
shift sequences, such as ISO-2022-JP, _citrus_iconv_convert will
always produce:
1. a shift sequence from the initial state to some nondefault state,
   like from US-ASCII to JIS X 0208
2. the encoding of the desired characater
3. a shift sequence restoring the initial state
This is unnecessary if the output is already in the state needed to
encoded the desired character.  For example, this method produces
seven bytes to encode each YEN SIGN in ISO-2022-JP -- and fourteen,
to encode two consecutive ones -- even though the shift sequence is
only three bytes long and once shifted YEN SIGN takes only one byte.
Instead, convert the Unicode scalar value to a locale-dependent wide
character and encode that, by composing
- _citrus_iconv_convert
  => gives us a multibyte encoding of the character from the initial
     state (and restoring the initial state afterward)
- mbrtowc with initial conversion state
  => gives us the single wide character representation
     XXX If combining characters are possible here, this may fail.
- wcrtomb with caller's conversion tsate
  => gives us a state-dependent multibyte encoding of the character
XXX Is there a cheaper way to convert from Unicode scalar value to
locale-dependent wide character?  It is not obvious to me from the
largely undocumented Citrus machinery, but it would obviously be
better than this somewhat circuitous Rube Goldberg contraption of
chained multibyte APIs.

According to ISO/IEC 9899:201x (draft) 7.15 Alignment <stdalign.h> defines
four macros:
 - alignas which expands to _Alignas
 - alignof which expands to _Alignof
 - __alignas_is_defined and __alignof_is_defined which both expand to 1

The _Alignas declaration appears as one of the type specifiers to modify
the alignment requirement of the object being declared.

The _Alignof operator is used to query the alignment requirement of its
operand type.

ISO/IEC N3242=11-0012 (C++1x) and ISO/IEC N3797 (C++1y) both note a header
<cstdalign> which defines only __alignas_is_defined and shall not define
the alignas macro. It misses the alignof case as it's probably based on an
older C1x draft, which defined only alignas. Assume that this is a bug in
the standard and treat alignof the same way as alignas in C++11.

Allow to define alignas and alignof in C++ prior the C++11 standard. It
might be broken but a nonstandard C++ compiler might support C11-like
_Alignas and _Alignof. Note that it's fatal for g++(1) v.5.4.

Import <stdnoreturn.h>

This header conforms to the C11 standard
Reference: ISO/IEC 9899:201x 7.23 _Noreturn <stdnoreturn.h>

According to ISO/IEC 9899:201x (draft) <stdnoreturn.> defines the
noreturn macro which expands to _Noreturn.

The _Noreturn keyword appears in a function declaration and specifies
that the function does not return by reaching the end of the function
body.

Design choices:
 - don't implicitly break C++ code including this header with #error
   C++11 offers [[noreturn]] which conflicts with C11 _Noreturn

 - don't check for __STDC_VERSION__, everybody is free to reuse it with
   a nonstandard compiler not conforming to C11 but supporting _Noreturn

   gcc(1) and clang(1) support _Noreturn in -std=c99 and older standards

   this follows <stdbool.h> choice for not checking for C99

 - follow <stdbool.h> and declare the __noreturn_is_defined guard

 - use a standard header guard (_STDNORETURN_H_), similar to <stdbool.h>

Add userland part of posix_spawn. Libc functions imported from FreeBSD.
Based on Charles Zhang's summer of code project.

Migrate one last leftover bit (used only by the kernel now) to
sys/ufs/ufs and remove the old quota headers and no-longer-used shared
code. Ok by releng.

Add <quota.h> with the new libquota API.

This is the user/application API and does not include the kernel
interface. Definitions shared with the kernel are found in
<sys/quota.h>.

Since I've been working on a local branch I have taken the liberty of
moving the latest-so-far version of <quota.h> to the front of the
patch queue. This loses (a small amount of) history but has the
advantage of avoiding unnecessary version bumps of libquota.so.

Build and install ppath(3), property-list paths library.

Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting

Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

Add a new libquota library, which contains some blocks to build and/or
parse quota plists; as well as a getfsquota() function to retrieve quotas
for a single id from a single filesystem (whatever filesystem this is:
a local quota-enabled fs or NFS). This is build on functions getufsquota()
(for local filesystems with UFS-like quotas) and getnfsquota();
which are also available to userland programs.
move functions from quota2_subr.c to libquota or libprop as appropriate,
and ajust in-tree quota tools.
move some declarations from kernel headers to either sys/quota.h or
quota/quota.h as appropriate. ufs/ufs/quota.h still installed because
it's needed by other installed ufs headers.
ufs/ufs/quota1.h still installed as a quick&dirty way to get a code
using the old quotactl() to compile (just include ufs/ufs/quota1.h instead of
ufs/ufs/quota.h - old code won't compile without this change and this is
on purpose).
Discussed on tech-kern@ and tech-net@ (long thread, but not much about
libquota itself ...)

performance is about the same if setservent(0) is used and about an

Add C99 complex support, for double and float.

http://www.netlib.org/cephes/, from Stephen L. Moshier, incorporated and
redistributed with the NetBSD license by permission of the author.

Error behaviour and other boundary conditions (branch cuts)
need to be looked at.

For namespace sanity, I've done the rename/weak alias procedure to
most of the exported functions which are also used internally.
Didn't do so for sin/cos(f) yet because assembler implementations use
them directly, and renaming functions shared between the main libm

issues.
