Prevent blank lines in documentation code blocks to be signalled as
incorrect trailing whitespace.
Code blocks in documentation are 4-column aligned, and blank lines in
them should have exactly 4 columns of trailing whitespace to prevent
QEMU's wiki to render them as separate code blocks.

CHK-level checks have been removed from checkpatch or bumped to
errors, so there is no effect anymore for --strict/--subjective.
Furthermore, even most WARNs have been bumped to errors, with
WARN only reserved to things that patchew probably ought not
to complain about (and that maintainers probably will notice
anyway during review if they are extreme).
Default to exiting with success even if there are WARN-level
failures, and cause --strict to fail for warnings. Maintainers
that want to have a strict 80-character limit for their subsystem
can add it to a commit hook for example.
The --subjective synonym is removed.

Line lengths above 80 characters do exist. They are rare, but
they happen from time to time. An ignored rule is worse than an
exception to the rule, so do the latter.
Some on the list expressed their preference for a soft limit that
is slightly lower than 80 characters, to account for extra characters
in unified diffs (including three-way diffs) and for email quoting.
However, there was no consensus on this so keep the 80-character
soft limit and add a hard limit at 90.

Linux uses tabs for indentation and checkpatch always complained about
automatically imported headers. update-linux-headers.sh could be modified to
expand tabs, but there is no real reason to complain about any ugly code in
Linux headers, so skip all hunk-related checks.

Commit 5d596c2's regexp assumes the error message string is the first
argument. Correct for error_report(), wrong for all the others.
Relax the regexp to match newline in anywhere. This might cause
additional false positives.
While there, update the list of error_reporting functions.

Renames look like this with git-diff(1) when diff.renames = true is set:
diff --git a/a b/b
similarity index 100%
rename from a
rename to b
This raises the "Does not appear to be a unified-diff format patch"
error because checkpatch.pl only considers a diff valid if it contains
at least one "@@" hunk.
This patch accepts renames and copies too so that checkpatch.pl exits
successfully when a diff only renames/copies files. The git diff
extended header format is described on the git-diff(1) man page.

Maybe there should be; but until there is, we should not flag
strtod() calls as something to replaced with qemu_strtod().
We also lack qemu_strtof() and qemu_strtold(), but as no one
has been using strtof() or strtold(), it's not worth complicating
the regex for them.
(Ironically, I had to use 'git commit -n' since checkpatch uses
TAB indents, in violation of its own recommendations.)

In some occasions, a patch [1] can start with a hunk containing a
simple type cast. At the time annotate_values() is run, the type is
unknown and the cast type is misinterpreted as a identifier, resulting
in an error if it is followed with a negative value:
ERROR: spaces required around that '-' (ctx:WxV)
It seems complex to catch all possible types in a cast expression. So,
as a fallback solution, let's add some common qemu types to the
typeList array.

Previously, an error was printed in cases such as:
{ [1] = 5, [2] = 6 }
The space passed OK after a curly brace, but not after a comma.
Now, a space before a square bracket is allowed, if a comma comes before
it.

We don't want newlines embedded in error messages. This seems to be a common
problem with new code so let's try to catch it with checkpatch.
This will not catch cases where newlines are inserted into the middle of an

The checkpatch.pl script has a special case to permit the following
operators to have no spaces around them:
<< >> & ^ | + - * / %
QEMU style prefers all operators to consistently have spacing around
them, so remove this special case handling. This avoids reviewers
having to manually note it during code review.

checkpatch currently loops on fpu/softfloat.c
Turns out this is fixed in the Linux version of checkpatch.
So this is a port of Andy Whitcrofts fix from Linux,
Original commit was commit 89a883530fe7 ("checkpatch: ## is not a
valid modifier")
As suggested by Peter Maydell for the QEMU version we drop the last "|"
as there seems to be no need for that. (FWIW, the kernel discusion about
that dried out:
