  - fix tables markups;
  - add some lists markups;

To print the pathname that will be used by shell in the current
environment, 'command -v' is a standardized way. [1]

'which' is also often used in scripts, but it is less portable.

When I worked on commit bd55f96f ("kbuild: refactor cc-cross-prefix
implementation"), I was eager to use 'command -v' but it did not work.
(The reason is explained below.)

I kept 'which' as before but got rid of '> /dev/null 2>&1' as I
thought it was no longer needed. Sorry, I was wrong.

It works well on my Ubuntu machine, but Alexey Brodkin reports noisy
warnings on CentOS7 when 'which' fails to find the given command in
the PATH environment.

  $ which foo
  which: no foo in (/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin)

Given that behavior of 'which' depends on system (and it may not be
installed by default), I want to try 'command -v' once again.

The specification [1] clearly describes the behavior of 'command -v'
when the given command is not found:

  Otherwise, no output shall be written and the exit status shall reflect
  that the name was not found.

However, we need a little magic to use 'command -v' from Make.

$(shell ...) passes the argument to a subshell for execution, and
returns the standard output of the command.

Here is a trick. GNU Make may optimize this by executing the command
directly instead of forking a subshell, if no shell special characters
are found in the command and omitting the subshell will not change the
behavior.

In this case, no shell special character is used. So, Make will try
to run it directly. However, 'command' is a shell-builtin command,
then Make would fail to find it in the PATH environment:

  $ make ARCH=m68k defconfig
  make: command: Command not found
  make: command: Command not found
  make: command: Command not found

In fact, Make has a table of shell-builtin commands because it must
ask the shell to execute them.

Until recently, 'command' was missing in the table.

This issue was fixed by the following commit:

| commit 1af314465e5dfe3e8baa839a32a72e83c04f26ef
| Author: Paul Smith <psmith@gnu.org>
| Date:   Sun Nov 12 18:10:28 2017 -0500
|
|     * job.c: Add "command" as a known shell built-in.
|
|     This is not a POSIX shell built-in but it's common in UNIX shells.
|     Reported by Nick Bowler <nbowler@draconx.ca>.

Because the latest release is GNU Make 4.2.1 in 2016, this commit is
not included in any released versions. (But some distributions may
have back-ported it.)

We need to trick Make to spawn a subshell. There are various ways to
do so:

 1) Use a shell special character '~' as dummy

    $(shell : ~; command -v $(c)gcc)

 2) Use a variable reference that always expands to the empty string
    (suggested by David Laight)

    $(shell command$${x:+} -v $(c)gcc)

 3) Use redirect

    $(shell command -v $(c)gcc 2>/dev/null)

I chose 3) to not confuse people. The stderr would not be polluted
anyway, but it will provide extra safety, and is easy to understand.

Tested on Make 3.81, 3.82, 4.0, 4.1, 4.2, 4.2.1

Adding SPDX license identifier is pretty safe; however, here is one
exception.

Since commit ec8f24b7 ("treewide: Add SPDX license identifier -
Makefile/Kconfig"), "make testconfig" would not pass.

When Kconfig detects a circular file inclusion, it displays error
messages with a file name and a line number prefixed to each line.

The unit test checks if Kconfig emits the error messages correctly
(this also checks the line number correctness).

Now that the test input has the SPDX license identifier at the very top,
the line numbers in the expected stderr should be incremented by 1.

At DT, files are being renamed to jason. Teach the script how to
handle such renames when used in fix mode.

There's a false positive on perf/util:

	tools/perf/util/s390-cpumsf.c: Documentation/perf.data-file-format.txt

The file is there at tools/perf/Documentation/, but the logic
with detects relative documentation references inside tools is
not capable of detecting it.

So, improve it.

There are at least two cases where a documentation file was gone
for good, but the text still mentions it:

1) drivers/vhost/vhost.c:
   the reference for Documentation/virtual/lguest/lguest.c is just
   to give credits to the original work that vhost replaced;

2) Documentation/scsi/scsi_mid_low_api.txt:
   It gives credit and mentions the old Documentation/Configure.help
   file that used to be part of Kernel 2.4.x

As we don't want to keep the script to keep pinpoint to those
every time, let's add a logic at the script to allow it to ignore
valid false-positives like the above.

Call the script every time a make docs target is selected, on
a simplified check mode.

With this change, the script will set two vars:

$min_version - obtained from `needs_sphinx` var inside
	       conf.py (currently, '1.3')

$rec_version - obtained from sphinx/requirements.txt.

With those changes, a target like "make htmldocs" will do:

1) If no sphinx-build/sphinx-build3 is found, it will run
   the script on normal mode as before, checking for all
   system dependencies and providing install hints for the
   needed programs and will abort the build;

2) If no sphinx-build/sphinx-build3 is found, but there is
   a sphinx_${VER}/bin/activate file, and if
   ${VER} >= $min_version (string comparation), it will
   run in full mode, and will recommend to activate the
   virtualenv. If there are multiple virtualenvs, it
   will string sort the versions, recommending the
   highest version and will abort the build;

3) If Sphinx is detected but has a version lower than
   $min_version, it will run in full mode - with will
   recommend creating a virtual env using sphinx/requirements.txt,
   and will abort the build.

4) If Sphinx is detected and version is lower than
   $rec_version, it will run in full mode and will
   recommend creating a virtual env using sphinx/requirements.txt.

   In this case, it **won't** abort the build.

5) If Sphinx is detected and version is equal or righer than
   $rec_version it will return just after detecting the
   version ("quick mode"), not checking if are there any
   missing dependencies.

Just like before, if one wants to install Sphinx from the
distro, it has to call the script manually and use `--no-virtualenv`
argument to get the hints for his OS:

    You should run:

	sudo dnf install -y python3-sphinx python3-sphinx_rtd_theme

While here, add a small help for the three optional arguments
for the script.

RHEL8 was already launched. This test won't get it, and will
do the wrong thing. Ok, we could fix it, but now we check
Sphinx version to ensure that it matches the minimal (1.3),
so there's no need for an explicit check there.
