Log:
[clang-tidy] Adding RestrictSystemIncludes check to Fuchsia module
Adding a check to restrict system includes to a whitelist. Given a list
of includes that are explicitly allowed, the check issues a fixit to
remove any system include not on that list from the source file.

+
+fuchsia-restrict-system-includes
+================================
+
+Checks for allowed system includes and suggests removal of any others.
+
+It is important to note that running this check with fixes may break code, as
+the fix removes headers. Fixes are applied to source and header files, but not
+to system headers.
+
+For example, given the allowed system includes 'a.h,b*':
+
+.. code-block:: c++
+
+ #include <a.h>
+ #include <b.h>
+ #include <bar.h>
+ #include <c.h> // Warning, as c.h is not explicitly allowed
+
+All system includes can be allowed with '*', and all can be disallowed with an
+empty string ('').
+
+Options
+-------
+
+.. option:: Includes
+
+ A string containing a comma separated glob list of allowed include filenames.
+ Similar to the -checks glob list for running clang-tidy itself, the two
+ wildcard characters are '*' and '-', to include and exclude globs,
+ respectively.The default is '*', which allows all includes.
