system_data_types.7: Minor tweaks to Alejandro Colomar's float_t/double_t patches

Signed-off-by: Michael Kerrisk <mtk.manpages@gmail.com>

system_data_types.7: srcfix

The contents of each type are a logical block that is indented as
a block.  They are not separate paragraphs that happen to be
indented separately, but a set of continuous paragraphs, all at
the same level, indented as a block from the list entry--the name
of the type--.  Therefore, it makes more sense to use block
indentation, represented by .RS/.RE, rather than indenting each
paragraph separately.  That way it's also easier to further indent
a separate paragraph inside a block, which happens for example in
the case of float_t & double_t.  It's simply much easier now to
use .IP specifically in those cases where you want to indent just
a single paragraph.

Also added an ending separator comment line just after the last
type.

Hi Michael,

I'd say that the cast doesn't fix any problems at all.  It silences a
valid warning, and I'd use a pragma for that (to be more explicit about
the intention of silencing a warning) if I do want -Wconversion enabled
(which usually I don't want, because it's too noisy) and I'm sure that
this won't overflow.  I'd limit the use casts to only when I *really*
need to.

I guess that if you enable -O3, the warning will vanish again because
the compiler will optimize away 'x' (but I didn't test).

ioctl_ns.2, stat.2: Fix signedness of printf specifiers

These variables are either of an unsigned integer type per POSIX;
or of an integer type per POSIX, that Linux defines as an unsigned integer type.

Print them with 'uintmax_t' instead of 'intmax_t' to avoid
big positive numbers being printed as negative numbers.

Bug report:
From: Konstantin Bukin @ 2020-09-13 15:04 UTC
  To: mtk.manpages; +Cc: Konstantin Bukin, linux-man

inode numbers are expected to be positive. Casting them to a signed type
may result in printing negative values. E.g. running example program on
the following file:

$ ls -li test.txt
9280843260537405888 -r--r--r-- 1 kbukin hardware 300 Jul 21 06:36 test.txt

results in the following output:

$ ./example test.txt
ID of containing device:  [0,480]
File type:                regular file
I-node number:            -9165900813172145728
Mode:                     100444 (octal)
Link count:               1
Ownership:                UID=2743   GID=30
Preferred I/O block size: 32768 bytes
File size:                300 bytes
Blocks allocated:         8
Last status change:       Tue Jul 21 06:36:50 2020
Last file access:         Sat Sep 12 14:13:38 2020
Last file modification:   Tue Jul 21 06:36:50 2020

Such erroneous reporting happens for inode values greater than maximum
value which can be stored in signed long. Casting does not seem to be
necessary here. Printing inode as unsigned long fixes the issue.

syscalls.2: Move system calls from discontinued ports out of main syscall list

Various ports that had their own indigenous system calls have
been discontinued. Remove those system calls (none of which had
manual pages!) to a separate part of the page, to avoid
