Note in the description of "jobs -p" that the process id returned is
also the process group identifier (that's a requirement from POSIX, and
is what we have always done - just not been explicit about in sh.1).
Add a note that this value and $! are not necessarily the same (currently,
and perhaps forever, never the same in a pipeline with 2 or more elements).

sun8icodec: Update for binding spec changes.

The allwinner,sun8i-a33-codec binding spec has changed[1] to allow for
#sound-dai-cells to be either 0 or 1, to allow exporting multiple DAIs
from the codec.

This change updates the driver to allow #sound-dai-cells of either 0 or 1
while still only supporting AIF1 for the time being.

x86: Add dtrace probes for interrupt handler entry and return.

Arguments:

0: interrupt handler function
1: interrupt handler's private cookie argument
2: MD struct intrhand pointer
3: return value (true if relevant to this handler, false if not)

The MD struct intrhand pointer makes the first two arguments
redundant, but we might reuse the signature of the first two
arguments for an MI SDT probe to make it easy to write MI dtrace
scripts for monitoring interrupt handlers.  The MD intrhand can be
used for getting more information about the interrupt like ih_level,
ih_pin, ih_slot, &c., which may not make sense as an MI API.

new tzcode 2022f

(christos)

Update to tzcode2022f

  Changes to code

    zic now supports links to links regardless of input line order.
    For example, if Australia/Sydney is a Zone, the lines
      Link Australia/Canberra Australia/ACT
      Link Australia/Sydney Australia/Canberra
    now work correctly, even though the shell commands
      ln Australia/Canberra Australia/ACT
      ln Australia/Sydney Australia/Canberra
    would fail because the first command attempts to use a link
    Australia/Canberra that does not exist until after the second
    command is executed.  Previously, zic had unspecified behavior if
    a Link line's target was another link, and zic often misbehaved if
    a Link line's target was a later Link line.

    Fix line number in zic's diagnostic for a link to a link.

    Fix a bug that caused localtime to mishandle timestamps starting
    in the year 2438 when reading data generated by 'zic -b fat' when
    distant-future DST transitions occur at times given in standard
    time or in UT, not the usual case of local time.  This occurs when
    the corresponding .zi Rule lines specify DST transitions with TO
    columns of 'max' and AT columns that end in 's' or 'u'.  The
    number 2438 comes from the 32-bit limit in the year 2038, plus the
    400-year Gregorian cycle.  (Problem reported by Bradley White.)

    On glibc 2.34 and later, which optionally supports 64-bit time_t
    on platforms like x86 where time_t was traditionally 32 bits,
    default time_t to 64 instead of 32 bits.  This lets functions like
    localtime support timestamps after the year 2038, and fixes
    year-2038 problems in zic when accessing files dated after 2038.
    To continue to limit time_t to 32 bits on these platforms, use
    "make CFLAGS='-D_TIME_BITS=32'".

    In C code, do not enable large-file support on platforms like AIX
    and macOS that no longer need it now that tzcode does not use
    off_t or related functions like 'stat'.  Large-file support is
    still enabled by default on GNU/Linux, as it is needed for 64-bit
    time_t support.

    In C code, prefer C23 keywords to pre-C23 macros for alignof,
    bool, false, and true.  Also, use the following C23 features if
    available: __has_include, unreachable.

    zic no longer works around Qt bug 53071, as the relevant Qt
    releases have been out of support since 2019.  This change affects
    only fat TZif files, as thin files never had the workaround.

    zdump no longer modifies the environ vector when compiled on
    platforms lacking tm_zone or when compiled with -DUSE_LTZ=0.
    This avoid undefined behavior on POSIX platforms.

inpcb: separate inpcb again to reduce the size of PCB for IPv4

The data size of PCB for IPv4 increased because of the merge of
struct in6pcb.  The change decreases the size to the original size by
separating struct inpcb (again).  struct in4pcb and in6pcb that embed
struct inpcb are introduced.

Even after the separation, users don't need to realize the separation
and only have to use some macros to access dedicated data.  For example,
inp->inp_laddr is now accessed through in4p_laddr(inp).

inpcb: integrate data structures of PCB into one

Data structures of network protocol control blocks (PCBs), i.e.,
struct inpcb, in6pcb and inpcb_hdr, are not organized well.  Users of
the data structures have to handle them separately and thus the code
is cluttered and duplicated.

The commit integrates the data structures into one, struct inpcb.  As a
result, users of PCBs only have to handle just one data structure, so
the code becomes simple.

One drawback is that the data size of PCB for IPv4 increases by 40 bytes
(from 248 bytes to 288 bytes).

.c files but that leads to other fallout I'm not really inclined to
diagnose right now.

merge upstream commit 9b3219ba544db82cdad3058b9872058739559944:

If rule_str ended in a "-", "l" was incremented one byte past the
end of the buffer.  This resulted in an out-of-bounds read when "l"
is dereferenced at the end of the loop.  It is safest to just return
early in this case since the condition occurs inside a nested loop.

bin/sh/miscbltin.c: revision 1.51
bin/sh/miscbltin.c: revision 1.52

PR bin/56972  Fix escape ('\') handling in sh read builtin.

In 1.35 (March 2005) (the big read fixup), most escape handling and IFS
processing in the read builtin was corrected.  However 2 cases were missed,
one is a word (something to be assigned to any variable but the last) in
which every character is escaped (the code was relying on a non-escaped char
to set the "in a word" status), and second trailing IFS whitespace at
the end of the line was being deleted, even if the chars had been escaped
(the escape chars are no longer present).

See the PR for more details (including the case that detected the problem).

After fixing this, I looked at the FreeBSD code (normally might do it
before, but these fixes were trivial) to check their implementation.

Their code does similar things to ours now does, but in a completely
different way, their read builtin is more complex than ours needs to
be (they handle more options).  For anyone tempted to simply incorporate
their code, note that it relies upon infrastructure changes elsewhere
in the shell, so would not be a simple cut and drop in exercise.

This needs pullups to -3 -4 -5 -6 -7 -8 and -9 (fortunately this is
happening before -10 is branched, so will never be broken this way there).

Don't output the error for bad usage (no var name given)
