The majority of pages use .nf/.fi in SYNOPSIS, but there are
still many that don't and use .br to achieve newlines. Fix many
of those. This brings greater consistency to the pages, which
eases editing and may ease future scripted edits to the pages.
Many of these changes were script-assisted, with some additional
manual edits.

Yet more clean-ups after commit
15d6565317.

Since glibc 2.29, there is a wrapper for getcpu(2).
The wrapper has only 2 arguments, omitting the unused
third system call argument. Rework the manual page
to reflect this.

Most pages use 'unsigned int' (and the kernel too).
Make them all do so.
$ find man? -type f \
| xargs sed -i \
-e 's/unsigned \*/unsigned int */g'
-e 's/unsigned "/unsigned int "/g';

The use of vertical white space in the SYNOPSIS sections
is rather inconsistent. Make it more consistent, subject to the
following heuristics:
* Prefer no blank lines between function signatures by default.
* Where many functions are defined in the SYNOPSIS, add blank
lines where needed to improve readability, possibly by using
blank lines to separate logical groups of functions.

The functions are all declared in <netdb.h>. <sys/socket.h> is only
needed for the AF_* constants.

Bring a bit more consistency to Feature Test Macro information
(mainly .PP between differnt FTM lists).
Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>
Use .PP (which gives a bit of vertical white space) rather than
.br to separate functions in Feature Test Macro requirement lists.

The Linux kernel uses 'unsigned int' instead of 'int' for the
'flags' parameter. As glibc provides no wrapper, use the same
type the kernel uses.
......
$ syscall='delete_module';
$ find linux/ -type f -name '*.c' \
|xargs pcregrep -Mn "(?s)^[\w_]*SYSCALL_DEFINE.\(${syscall},.*?\)";
linux/kernel/module.c:977:
SYSCALL_DEFINE2(delete_module, const char __user *, name_user,
unsigned int, flags)

This commit normalizes texts under sections other than SYNOPSIS

To easily distinguish documentation about glibc wrappers from
documentation about kernel syscalls, let's have a normalized
'Note' in the SYNOPSIS, and a further explanation in the page body
(NOTES in most of them), as already happened in many (but not all)
of the manual pages for syscalls without a wrapper. Furthermore,
let's normalize the messages, following membarrier.2 (because it's
already quite extended), so that it's easy to use grep to find
those pages.
To find these pages, we used:
$ grep -rn wrapper man? | sort -V
and
$ grep -rni support.*glibc | sort -V
delete_module.2, init_module.2: glibc 2.23 is no longer
maintained, so we changed the notes about wrappers, to say that
there are no glibc wrappers for these system calls; see NOTES.
We didn't fix some obsolete pages such as create_module.2.
