(function-history): New symbol property (bug#53632)
Rework the code we have in Fdefalias that tries to keep track
of definitions so as to be able to undo them later.
We used to store in `load-history` when an autoload is redefined as
a non-autoload and in the `autoload` symbol property we used to store
the autoload data that used to be used before it got overriden.
Instead, store the history of the function definition of
a symbol in its `function-history` symbol property.
To make this list cheap in the default case, the latest value is not stored
in the list (since it's in the `symbol-function`) and neither is the first
file. So if there's only been a single definition (the most common case),
the list is empty and the property is just not present at all.
The patch also gets rid of the `autoload` vs `defun` distinction in
`load-history` which seems unnecessary (a significant part of the
motivation for this patch was to get rid of the special handling of
autoloads in this part of the code).
* src/data.c (add_to_function_history): New function.
