    Dataset and PsppireDict to have their own copy of struct dictionary

commit e0f9210e814d03bc43b6a9b30a402e403d5666b9

    lexer: Add support for embedded \0 bytes and missing trailing new-line.
    
    The lexer, at a low level, has not supported \0 bytes in the input stream
    because it used such a byte as the end-of-input indicator.  This caused
    some awkwardness for the higher-level lexer, which had to remove and flag
    \0 bytes as it read them.  This caused a bug in the higher-level lexer,
    which raised an error for each \0 byte it removed but did so when the
    lexer was in an intermediate state, which could read uninitialized data.
    
    This commit fixes the problem by adding support for \0 bytes to the
    low-level lexer (segmenter).  At the same time, it adds support for input
    that doesn't end in a new-line character.
    
    Bug #54664.
    Thanks to Tianxiao Gu for reporting this bug.

commit 89198b80bfd7e3893ed7499ba25b9bf94faaffb9

    DO REPEAT: Avoid relying on null terminators.
    
    find_dummy_var() currently relies on the string passed in to have a null
    terminator (even though it accepts a length).  This is safe in the current
    tree but an upcoming commit will not ensure that it is null-terminated, so
    this commit removes the dependency.

    command-name: Avoid read past end of input buffer in find_word().
    
    When the input substring S is not null-terminated, find_word() could read
    past its end looking for a non-digit.  This fixes the problem.
