cflow-1.5-bp151.3.1

- Update to version 1.5:
  * Correctly handle functions returning struct/union (fixes bug
    [#31792])
  * Gracefully handle invalid inputs (fixes bug #44113)
  * Debugging output goes to stderr
  * Add a manpage
  * Consistent use of exit codes
- Cleanup spec file with spec-cleaner
- Use url for source
- Add gpg signature

- update to cflow-1.4
  * Symbol aliases
    The `--symbol' option has been extended to allow for defining
    symbol aliases.  Aliases are useful for declaring reserved
    words such as `__restrict' or `__inline'.  For example,
    the option `--symbol __restrict:=restrict' instructs cflow
    to treat `__restrict' exactly as `restrict'.
  * New syntactic class: qualifiers
    Tokens in this class can legitimately appear in place of C
    qualifiers, such as `static' or `inline'.  This class is useful
    for some compiler-depending keywords, such as `__extension__'
    in gcc.  The usual declaration of this symbol is `--symbol
    __extension__:qualifier'.
  * Speed up recursive call detection.
  * Fix parsing of typedefs after `struct'.
  * Fix the output of branch marks in tree mode.
  * Fix processing of static inline functions (RH bug 650716).
