    Bug 798112 - An error occurred while processing mysql ...
    
    A "Feature" of MYSQL is that it allows C-style backslash escapes
    in string constants and replaces them with the actual character
    (e.g. \n is converted to 0x0a). This causes round trip problems
    if the escape is one of the allowed ones and a MYSQL error if it
    isn't.
    
    Disable the feature so that MYSQL follows the SQL standard.

    [test-backend-dbi] Fix copying hidden property.
    
    So that it actually copies it to the *other* root account.

    Make prototypes static for autoclear unit test
    
    With the explicit prototypes not marked as static unit test builds on Debian
    Buster (using buster-backports) fail with
    
    error: testing::internal::ParamGenerator<TestCase*> gtest_InstantiationAutoClearTestAutoClearTest_EvalGenerator_() was declared extern and later static [-fpermissive]
    
    According to the comment preceding the declaration the only intent of the
    explicit prototype (in newer versions of googletest implicitly defined by the
    GTEST macros) seems to be to silence a warning which would cause a build
    failure on Ubuntu 18.04 when using -Werror.
    
    Builds on Debian unstable seem to build just fine without this explicit
    declaration, hence I consider it safe to just drop it. However, builds on
    Ubuntu 18.04 then fail (see above).
    
    Making the prototypes as static should make both build environments happy.
