initial_terminal without relying on its name (bug#80629).

Eliminate 'vtable--limit-string' in favor of the more efficient
'truncate-string-pixelwise'. Remove extraneous pre-measurement
calls to 'string-pixel-width' and ellipsis concatenation as
'truncate-string-pixelwise' does both.

the default returned by 'truncate-string-ellipsis'.

block that doesn't use :rev, and instead shows that you can just
pass a URL as a string to :vc.

Remove `error-data` from the new error API: it is not really
compatible with a more abstract view of error descriptors, and
in practice it seems to be used only in two ways (both of them rare):
- To add some contextual info to an error. We should maybe add
a dedicated support for that, but it's not clear what shape it
should take, ideally (there was a discussion about with Alan
and myself in emacs-devel a few years ago).
- To do some other massaging whose correctness is dubious anyway.

the possibility of passing a whole error descriptor to re-signal it.

DATA is `nil` and ERROR_SYMBOL is an error descriptor.
* lisp/subr.el (error-type-p, error--p, error-type, error-data)
(error-has-type-p, error-slot-value): New function.
* doc/lispref/control.texi (Handling Errors): Prefer "error descriptor"
to "error description". Use the new single-arg call to `signal` to
re-throw an error.
Document `error-type`, `error-data` and `error-slot-value`.
(Error Symbols): Document the new functions `error-type-p` and
`error-has-type-p`.
* lisp/vc/vc-dispatcher.el (vc-display-failed-async-commands):
New user option.
