Alexander Kornienko 0b024619df [clang-tidy] Clarify message for the google-explicit-constructor check
Use "constructors that are callable with a single argument" instead of
"single-argument constructors" when referring to constructors using default
arguments or parameter packs.

Samuel Benzaquen 3199b9a8b5 Fix false positive on anonymous namespaces in headers.
Summary:
Anynoumous namespaces inject a using directive into the AST to import
the names into the containing namespace.
We should not have them in headers, but there is another warning for
that.

Summary:

detecting redundant casts between typedefs to the same type - emit a more
specific warning and don't automatically fix them.

Alexander Kornienko 1efc425551 [clang-tidy] Default options in modules.
Summary:
This patch allows modules to specify default options for the checks
defined in them. This way a sufficiently configurable check can be registered in
multiple modules with different default options. E.g. the SpacesBeforeComments
option may be set to 1 for the "llvm-namespace-comments" check and to 2 for the
"google-readability-namespace-comment" check without modifying or extending the
check code.

This patch also registers the google-readability-braces-around-statements check
with suitable defaults.

takes "default" options instead of "fallback" options, as it now uses these when
an option is not set in the configuration file (one exception is the checks
list).
