Use the correct macro (I, B) for the font change of one argument, not
those that are used for alternating two fonts, like "BR", "IR", "RB",
or "RI".

This patch does only the following:
* Order SEE ALSO entries first by section name, then alphabetically
within section
* Adds one or two missing commas in SEE ALSO lists
* Removes one or two periods that were (inconsistently) used
at the end of SEE ALSO lists.

This patch introduces
-d, --deadline
-T, --sched-runtime
-D, --sched-deadline

Transform some of them into copyright lines.
Also fix three header lines and snip some trailing whitespace.

And mention in manual that the default is referring to the internal
default of this command, not the Linux system default. Manual page
example also tries to be a little more complete how to use the command.

Use dates without the day, use the full month name, put "util-linux" in
the lower left corner, and "User Commands" or "System Administration"
at the top center.
Also improve here and there the one-line program description.

Currently this program works only with the master thread. Add a '-t'
option to propagate changes to the entire group of threads.
Example:
root@offworld:~/projects/util-linux/schedutils# ls /proc/2111/task/
2111 2112 2119 2121 2138 2139 2159 2160
root@offworld:~/projects/util-linux/schedutils# ./chrt -p 2111
pid 2111's current scheduling policy: SCHED_RR
pid 2111's current scheduling priority: 3
root@offworld:~/projects/util-linux/schedutils# ./chrt -t -p 2 2111
root@offworld:~/projects/util-linux/schedutils# ./chrt -p 2112
pid 2112's current scheduling policy: SCHED_RR
pid 2112's current scheduling priority: 2
root@offworld:~/projects/util-linux/schedutils# ./chrt -p 2111
pid 2111's current scheduling policy: SCHED_RR
pid 2111's current scheduling priority: 2

This new option allows to set SCHED_RESET_ON_FORK flag for FIFO and RR
policies.
Example:
$ chrt --fifo --reset-on-fork 1 /bin/bash
$ schedutils/chrt --pid $$
pid 31579's current scheduling policy: SCHED_FIFO|SCHED_RESET_ON_FORK
pid 31579's current scheduling priority: 1

SCHED_FIFO, SCHED_OTHER, SCHED_RR are part of POSIX 1003.1b Process
Scheduling, so it is correct to assume they always exists.
SCHED_BATCH and SCHED_IDLE are Linux specific, we should not assume
they exists.
Defining SCHED_BATCH and SCHED_IDLE to random values (ie the ones found
on Linux systems) is not an option as they may *collide* with the one of
other systems. For example on GNU/kFreeBSD we have:
#define SCHED_RR 3
and on Linux we have:
#define SCHED_BATCH 3

This is temporary workaround and it will be removed in 2.14 when
minimal number of people will use old systems where is not defined
SCHED_BATCH in (bits/)sched.h.
