Dr. Matthias St. Pierre fbbfd128c9 Fix header file include guard names
Make the include guards consistent by renaming them systematically according
to the naming conventions below

The public header files (in the 'include/openssl' directory) are not changed
in 1.1.1, because it is a stable release.

For the private header files files, the guard names try to match the path
specified in the include directives, with all letters converted to upper case
and '/' and '.' replaced by '_'. An extra 'OSSL_' is added as prefix.

* Test cases that share common setup should use the helper
* SETUP_TEST_FIXTURE and EXECUTE_TEST macros for test case functions.
*
* SETUP_TEST_FIXTURE will call set_up() to create a new TEST_FIXTURE_TYPE
* object called "fixture". It will also allocate the "result" variable used
* by EXECUTE_TEST. set_up() should take a const char* specifying the test
* case name and return a TEST_FIXTURE_TYPE by reference.
*
* EXECUTE_TEST will pass fixture to execute_func() by reference, call
* tear_down(), and return the result of execute_func(). execute_func() should
* take a TEST_FIXTURE_TYPE by reference and return 1 on success and 0 on
* failure. The tear_down function is responsible for deallocation of the
* result variable, if required.
*
* Unit tests can define their own SETUP_TEST_FIXTURE and EXECUTE_TEST
* variations like so:
*
* #define SETUP_FOOBAR_TEST_FIXTURE()\
* SETUP_TEST_FIXTURE(FOOBAR_TEST_FIXTURE, set_up_foobar)
*
* #define EXECUTE_FOOBAR_TEST()\
* EXECUTE_TEST(execute_foobar, tear_down_foobar)
*
* Then test case functions can take the form:
*
* static int test_foobar_feature()
* {
* SETUP_FOOBAR_TEST_FIXTURE();
* [...set individual members of fixture...]
* EXECUTE_FOOBAR_TEST();
