scripts/kernel-doc: strip QEMU_ from function definitions

Some packaged versions of Sphinx (fedora33/alpine so far) have issues
with the annotated C code that kernel-doc spits out. Without knowing
about things like QEMU_PLUGIN_EXPORT it chokes trying to understand
the code. Evidently this is a problem for the kernel as well as the
long stream of regex substitutions we add to in this patch can attest.

Fortunately we have a fairly common format for all our compiler
shenanigans as applied to functions so lets just filter them all out.

scripts: kernel-doc: remove unnecessary change wrt Linux

A comment in kernel-doc mentions QEMU's qatomic_set macro, but since
this code originated in Linux we should just revert it and stay as close
to the kernel's copy of the script as possible.

The change was introduced (more or less unintentionally) in QEMU commit
commit d73415a31547, which did a global search-and-replace of QEMU's
atomic access macros.

scripts: kernel-doc: fix line number handling

Address several issues related to pointing to the wrong line
number:

1) ensure that line numbers will always be initialized

When section is the default (Description), the line number
is not initializing, producing this:

$ ./scripts/kernel-doc --enable-lineno ./drivers/media/v4l2-core/v4l2-mem2mem.c|less

**Description**

#define LINENO 0
In case of streamoff or release called on any context,
1] If the context is currently running, then abort job will be called
2] If the context is queued, then the context will be removed from
the job_queue

Which is not right. Ensure that the line number will always
be there. After applied, the result now points to the right location:

**Description**

#define LINENO 410
In case of streamoff or release called on any context,
1] If the context is currently running, then abort job will be called
2] If the context is queued, then the context will be removed from
the job_queue

2) The line numbers for function prototypes are always + 1,
because it is taken at the line after handling the prototype.
Change the logic to point to the next line after the /** */
block;

3) The "DOC:" line number should point to the same line as this
markup is found, and not to the next one.

Probably part of the issues were due to a but that was causing
the line number offset to be incremented by one, if --export
were used.

scripts: kernel-doc: allow passing desired Sphinx C domain dialect

When kernel-doc is called via kerneldoc.py, there's no need to
auto-detect the Sphinx version, as the Sphinx module already
knows it. So, add an optional parameter to allow changing the
Sphinx dialect.

As kernel-doc can also be manually called, keep the auto-detection
logic if the parameter was not specified. On such case, emit
a warning if sphinx-build can't be found at PATH.

I ended using a suggestion from Joe for using a more readable
regex, instead of using a complex one with a hidden group like:

m/^(\d+)\.(\d+)(?:\.?(\d+)?)/

in order to get the optional <patch> argument.

scripts: kernel-doc: don't mangle with parameter list

While kernel-doc needs to parse parameters in order to
identify its name, it shouldn't be touching the type,
as parsing it is very difficult, and errors happen.

One current error is when parsing this parameter:

const u32 (*tab)[256]

Found at ./lib/crc32.c, on this function:

u32 __pure crc32_be_generic (u32 crc, unsigned char const *p, size_t len, const u32 (*tab)[256], u32 polynomial);

The current logic mangles it, producing this output:

const u32 ( *tab

That's something that it is not recognizeable.

So, instead, let's push the argument as-is, and use it
when printing the function prototype and when describing
each argument.

This is happening with perl version 5.30.3, but I'm not
so sure if this is a perl bug, or if this is due to something
else.

In any case, fixing it is easy. Basically, when "-internal"
parameter is used, the process_export_file() function opens the
handle "IN". This makes the line number to be incremented, as the
handler for the main open is also "IN".

Fix the problem by using a different handler for the
main open().

While it could be relaxed with some configurations, there are
several corner cases that it would make it hard to maintain,
and will require teaching conf.py about several macros.

So, let's instead use the :c:macro notation. This will
produce an output that it is not as nice as currently, but it
should still be acceptable, and will provide cross-references,
removing thousands of warnings when building with newer
versions of Sphinx.

kernel-doc: add support for ____cacheline_aligned attribute

Subroutine dump_struct uses type attributes to check if the struct
syntax is valid. Then, it removes all attributes before using it for
output. `____cacheline_aligned` is an attribute that is
not included in both steps. Add it, since it is used by kernel structs.

Based on previous patch to add ____cacheline_aligned_in_smp.
Motivated by patches to reorder this attribute to before the
variable name. Whilst we could do that in all cases, that would
be a massive change and it is more common in the kernel to place
this particular attribute after the variable name. A quick grep
suggests approximately 400 instances of which 341 have this
attribute just before a semicolon and hence after the variable name.

scripts/kernel-doc: optionally treat warnings as errors

The kbuild bot recently added the W=1 option, which triggered
documentation cleanups to squelch hundreds of kernel-doc warnings.

To make sure new kernel contributions don't add regressions to
kernel-doc descriptors, this patch suggests an option to treat
warnings as errors in CI/automated tests.

A -Werror command-line option is added to the kernel-doc script. When
this option is set, the script will return the number of warnings
found. The caller can then treat this positive return value as an
error and stop the build.

Using this command line option is however not straightforward when the
kernel-doc script is called from other scripts. To align with typical
kernel compilation or documentation generation, the Werror option is
also set by checking the KCFLAGS environment variable, or if
KDOC_WERROR is defined, as in the following examples:

KCFLAGS="-Wall -Werror" make W=1 sound/
KCFLAGS="-Wall -Werror" make W=1 drivers/soundwire/
KDOC_WERROR=1 make htmldocs

Note that in the last example the documentation build does not stop,
only an additional log is provided.
