Arne Welzel 171846a37a parse.y/directives: Reject directives as statements 
Avoid the issue outlined in #2289 where the @if or @else is taken as the
statement of an `if`, `for` or `while` by rejecting such constructs.

Effectively this means the following scripts are now rejected:

    # Print's "cond true" with Zeek 5.0 even though the `if ( F )`
    # should be in effect.

    if ( F )
        @if ( T )
            print "cond true";
        @else
            print "cond false";
        @endif

or

    # Print's "hello" once with Zeek 5.0
    local v = vector( 1, 2, 3 );

    for ( i in v )
        @if ( T )
        print("hello")
        @endif

To make above work as intended, additional braces can be used.

    if ( T )
        {
    @if ( cond )
            print "cond true";
    @else
            print "cond false";
    @endif
        }

    for ( i in v )
        {
    @if ( T )
        print("hello")
    @endif
        }

README 

This directory contains suites for testing for Zeek's correct
operation:

    btest/
        An ever-growing set of small unit tests testing Zeek's
        functionality.

    external/
        A framework for downloading additional test sets that run more
        complex Zeek configuration on larger traces files. Due to their
        size, these are not included directly. See the README for more
        information. 

    scripts/
        Helpers scripts used by some tests.
