    Dramatically improve source recording on SYS::SOURCE plist for a symbol (Alan Ruttenberg) · e435b86f
    The interface to recording information on the SYS:%SOURCE plist for a
    symbol is now deprecated and will be removed with abcl-1.7.
    Source information for ABCL is now recorded on the SYS::SOURCE
    property.  The appropiate information for type is recorded by the
        record-source-information-by-type (name type &optional source-pathname source-position)
    TYPE is either a symbol or list.
    Source information for functions, methods, and generic functions are
    represented as lists of the following form:
        (:generic-function function-name)
        (:function function-name)
        (:method method-name qualifiers specializers)
    Where FUNCTION-NAME or METHOD-NAME can be a either be of the form
    'symbol or '(setf symbol).
    Source information for all other forms have a symbol for TYPE which is
    one of the following:
    :class, :variable, :condition, :constant, :compiler-macro, :macro
    :package, :structure, :type, :setf-expander, :source-transform
    These values follow SBCL'S implemenation in SLIME
    c.f. <https://github.com/slime/slime/blob/bad2acf672c33b913aabc1a7facb9c3c16a4afe9/swank/sbcl.lisp#L748>
    Modifications are in two places, one at the definitions, calling
    record-source-information-by-type and then again in the file-compiler,
    which writes forms like
        (put 'source name (cons (list type pathname position) (get 'source name)))
    In theory this can lead to redundancy if a fasl is loaded again and
    again. I'm not sure how to fix this yet. Forms in the __loader__ get
    called early in build when many of the sequence functions aren't
    present.  Will probably just filter when presenting in slime.
