All the xen stable APIs define handle types of the form:
xen<subject of API>_handle
and some define additional handle types of the form:
xen<subject of API>_<purpose of handle>_handle
Examples of these are xenforeignmemory_handle and
xenforeignmemory_resource_handle.
Both of these types will be misparsed by checkpatch if they appear as the
first token in a line since, as types defined by an external library, they
do not conform to the QEMU CODING_STYLE, which suggests CamelCase.
A previous patch (5ac067a24a) added xendevicemodel_handle to the list
of types. This patch changes that to xen\w+_handle such that it will
match all Xen stable API handles of the forms detailed above.

Some find using utf-8 in commit logs inappropriate.
Some patch commit logs contain unintended utf-8 characters when doing
things like copy/pasting compilation output.
Look for the start of any commit log by skipping initial lines that look
like email headers and "From: " lines.
Stop looking for utf-8 at the first signature line.

Conflicts:
QEMU does not have CHK(), use WARN() instead.
QEMU WARN() only takes one argument, drop the 'type' value in the
first argument.

This avoids checkpatch misparsing (as statements) long function
definitions or declarations, which sometimes start with constructs
like this:
static inline int xendevicemodel_relocate_memory(
xendevicemodel_handle *dmod, domid_t domid, ...
The type xendevicemodel_handle does not conform to Qemu CODING_STYLE,
which would suggest CamelCase. However, it is a type defined by the
Xen Project in xen.git. It would be possible to introduce a typedef
to allow the qemu code to refer to it by a differently-spelled name,
but that would obfuscate more than it would clarify.

Sometimes, we want to refer to really long URLs, but checkpatch
balks, and we have to manually bypass the check. URL shorteners
may be nice at reducing long links, but it's hard to guarantee the
shortened link will live as long as the real target, and it is
also nice to see the original target without having to load the
shortened URL through a browser. So exempt a line containing
only a URL from the long-line syntax check.

Adding check for `while` and `for` statements, which condition has more than
one line.
The former checkpatch.pl can check `if` statement, which condition has more
than one line, whether block misses brace round, like this:
'''
if (cond1 ||
cond2)
statement;
'''
But it doesn't do the same check for `for` and `while` statements.
Using `(?:...)` instead of `(...)` in regex pattern catch.
Because `(?:...)` is faster and avoids unwanted side-effect.

Use of a loop construct for code that is not intended to repeat
does not make much idiomatic sense, except in one place: it is a
common usage in macros in order to wrap arbitrary code with
single-statement semantics. But when used in a macro, it is more
typical for the caller to supply the trailing ';' when calling
the macro.
Although qemu coding style frowns on bare:
if (cond)
statement1;
else
statement2;
where extra semicolons actually cause syntax errors, we still
want our macro styles to be easily copied to other projects.
Thus, declare it an error if we encounter any form of 'while (0)'
with a semicolon in the same line.

stgit produces patch files that lack the ".patch" extensions. Others
might be using ".diff" too. But since we are already limiting source files
to only a handful of extensions, we can reuse that in the mode selection
code.
While at it, do not match "../foo" as a branch name.

The script doesn't know about all possible types and learn them as
it parses the code. If it reaches a line with a type cast but the
type isn't known yet, it is misinterpreted as an identifier.
For example the following line:
foo = (hwaddr) -1;
results in the following false-positive to be reported:
ERROR: spaces required around that '-' (ctx:VxV)
Let's add this standard QEMU type to the list of pre-known types.

Currently before submitting a series, devs should run checkpatch.pl
across each patch to be submitted. This can be automated using a
command such as:
git rebase -i master -x 'git show | ./scripts/checkpatch.pl -'
This is rather long winded to type, so this patch introduces a way
to tell checkpatch.pl to validate a series of GIT revisions.
There are now three modes it can operate in 1) check a patch 2) check a source
file, or 3) check a git branch.
If no flags are given, the mode is determined by checking the args passed to
the command. If the args contain a literal ".." it is treated as a GIT revision
list. If the args end in ".patch" or equal "-" it is treated as a patch file.
Otherwise it is treated as a source file.
This automatic guessing can be overridden using --[no-]patch --[no-]file or
--[no-]branch
For example to check a GIT revision list:
$ ./scripts/checkpatch.pl master..
total: 0 errors, 0 warnings, 297 lines checked
b886d352a2bf58f0996471fb3991a138373a2957 has no obvious style problems and is ready for submission.
total: 0 errors, 0 warnings, 182 lines checked
2a731f9a9ce145e0e0df6d42dd2a3ce4dfc543fa has no obvious style problems and is ready for submission.
total: 0 errors, 0 warnings, 102 lines checked
11844169bcc0c8ed4449eb3744a69877ed329dd7 has no obvious style problems and is ready for submission.
If a genuine patch filename contains the characters '..' it is
possible to force interpretation of the arg as a patch
$ ./scripts/checkpatch.pl --patch master..
will force it to load a patch file called "master..", or equivalently
$ ./scripts/checkpatch.pl --no-branch master..
will simply turn off guessing of GIT revision lists.
