If there's memset(x, y, 0) in the code it's most likely a mistake. The
checker suggests a fix-it to swap 'y' and '0'.
I think this has the potential to be promoted into a general clang warning
after some testing in clang-tidy.

This change contains of two checkers that warn about
1. anonymous namespaces in header files.
2. 'using namespace' directives everywhere.

Summary:
Those are considered unsafe and should be replaced with simple pointers or
full copies. It recognizes both std::string and ::string.

Imagine, hypothetically, that you had a build of clang-tidy that enabled
the google-* checks by default. If you had such a binary, then this
test would fail. Making it pass in that configuration isn't such a bad
thing.

Summary:
We still allow the escape hatch foo(int /*x*/) and also suggest this
in a fixit. This is more powerful than the corresponding cpplint.py check
it also flags functions with multiple arguments as naming all arguments is
recommended by the google style guide.

Those may be incompatible with C++11 and are unnecessary. We suggest
removing the template arguments when they match the types of the make_pair
arguments or replace it with std::pair and explicit template arguments when
not.

This looks for swapped arguments by looking at implicit conversions of arguments
void Foo(int, double);
Foo(1.0, 3); // Most likely a bug

Summary:
This patch implements a subset of possible replacements of C-style
casts with const_cast/static_cast/reinterpret_cast. This should cover a large
portion of cases in real code. Handling of a few more cases may be implemented
eventually.

The goal is to find code like the example below, which is likely a typo
where someone meant to write "if (*b)".
bool *b = SomeFunction();
if (b) {
// b never dereferenced
}
This checker naturally has a relatively high false positive rate so it
applies some heuristics to avoid cases where the pointer is checked for
nullptr before being written.

- Remove unused includes.
- Minor wording fix.
- Added support to check for clang-tidy messages to check_clang_tidy_fix.sh
= Updated test case.

Those often cause use after free bugs and should be generally avoided.
Technically it is safe to have a Twine with >=2 components in a variable
but I don't think it is a good pattern to follow. The almost trivial checker
comes with elaborated fix-it hints that turn the Twine into a std::string
if necessary and otherwise fall back to the original type if the Twine
is created from a single value.

Summary:
This patch removes " [check-name]" from the end of
ClangTidyMessage::Message. The " [check-name]" part is only appended when
printing diagnostics on the console. Clang errors are now marked with
"clang-diagnostic-error" check name, remarks and unknown warnings are marked
with "clang-diagnostic-unknown".

Summary:
The first version failed the SubstNonTypeTempateParmExpr-related test
on some buildbots. This one uses the new substNonTypeTempateParmExpr matcher to
filter out implicit C-style casts.
This patch depends on D4327.
