.PP and .IP are redundant just before .SH or .SS.
Remove them.

Since kernel commit a280d6dc77eb
("ipc/sem: introduce semctl(SEM_STAT_ANY)"),
it only skips read access check when using SEM_STAT_ANY command.
And it should use the semid_ds struct instead of seminfo struct.
Fix this.

In the RETURN VALUE sections, a number of different wordings
are used in to describe the fact that 'errno' is set on error.
There's no reason for the difference in wordings, since the same
thing is being described in each case. Switch to a standard
wording that is the same as FreeBSD and similar to the wording
used in POSIX.1.
In this change, miscellaneous descriptions of the setting
of 'errno' are reworded to the norm of "is set to indicate
the error".

The current mark-up renders poorly. To resolve this, move
the type information into a separate line.

Since we are using .nf/.fi to bracket FTM info, escaping
space characters serves no space and clutters the source.

- Group macros by kinds.
- Align so that it's easiest to distinguish differences
between related macros.
(Align all continuations for consistency on PDF.)
- Fix minor typos.
- Remove redundant text:
'The macro xxx() ...':
The first paragraph already says that these are macros.
'circular|tail|... queue':
Don't need to repeat every time.
Generic text makes it easier to spot the differences.
- Fit lines into 78 columns.
- Reorder descriptions to match SYNOPSIS,
and add subsections to DESCRIPTION.
- srcfix: fix a few semantic newlines.
I noticed a bug which should be fixed next:
CIRCLEQ_LOOP_*() return a 'struct TYPE *'.

Change `RES_USE_EDNSO` to `RES_USE_EDNS0`, defined in
`resolv.h`. (This is written correctly in `man3/resolver.3` in this
same repo.) Helps with grepping and internet searches!

Various ATTRIBUTES table improvements following the previous
commit. In particular, make use of T{...T} to allow wrapping
in table cells that have a lot of text.

Make the formatting more consistent inside the tables in the
ATTRIBUTES sections. Make the source code more uniform; in
particular, eliminate the use of custom tweaks using
'lbwNN'/'lwNN' and .br macros. In addition, ensure that
hyphenation and text justification do not occur inside the tables.
This is a script-driven edit:
[[
PAGE_LIST=$(git grep -l 'SH ATTRIBUTES' man[23])
# Strip out any preexisting .sp/.br/.ad macros
sed -i '/SH ATTR/,/^\.SH/{/^\.sp/d; /^\.br/d; /\.ad/d}' $PAGE_LIST
# Eliminate any use of 'wNN' in tables; default first column
# to fill unused space
sed -i '/SH ATTR/,/^\.SH/s/lbw[0-9]*/lb/g' $PAGE_LIST
sed -i '/SH ATTR/,/^\.SH/s/lw[0-9]*/l/g' $PAGE_LIST
sed -i '/SH ATTR/,/^\.SH/s/^lb /lbx /' $PAGE_LIST
# Nest the tables inside ".ad l"+".nh" and ".hy"+".ad"+".sp 1"
# ".ad l" ==> no right justification of text in table cells
# ".nh" ==> No hyphenation in table cells
# ".sp 1" ==> ensure a blank line before the next section heading
sed -i '/SH ATTR/,/^\.SH/{/\.TS/i.ad l\n.nh
}' $PAGE_LIST
sed -i '/SH ATTR/,/^\.SH/{/\.TE/a.hy\n.ad\n.sp 1
}' $PAGE_LIST
# In a few of the tables, the third column has a lot of text, so
# make that column wide (rather than the first column)
sed -i '/^lbx/{s/lbx/lb/;s/lb$/lbx/}' \

In the SYNOPSIS, a long function prototype may need to be
continued over to the next line. The continuation line is
indented according to the following rules:
1. If there is a single such prototype that needs to be continued,
then align the continuation line so that when the page is
rendered on a fixed-width font device (e.g., on an xterm) the
continuation line starts just below the start of the argument
list in the line above. (Exception: the indentation may be
adjusted if necessary to prevent a very long continuation line
or a further continuation line where the function prototype is
very long.)
Thus:
int tcsetattr(int fd, int optional_actions,
const struct termios *termios_p);
2. But, where multiple functions in the SYNOPSIS require
continuation lines, and the function names have different
lengths, then align all continuation lines to start in the
same column. This provides a nicer rendering in PDF output
(because the SYNOPSIS uses a variable width font where
spaces render narrower than most characters).
Thus:
int getopt(int argc, char * const argv[],
const char *optstring);
int getopt_long(int argc, char * const argv[],
const char *optstring,
const struct option *longopts, int *longindex);

it should not be listed as the first FTM for lstat().

Generally, place '||' at start of a line, rather than the end of
the previous line.
Rationale: this placement clearly indicates that that each piece
is an alternative.
