Since the location of those files changes between build time and
installation time, this requires to tweak the file name used in those
(#$ . NNN) references during the dump so they don't hardcode the build
directory. We do it in the same way as was already done for those
same file names in `load-history`, except we convert them back to
absolute file names more lazily (i.e. when fetching the actual
docstring rather than at startup), which requires remembering the
`lisp-dir` computed at startup in the new `lisp-directory` variable.
* src/Makefile.in ($(etc)/DOC): Don't scan Lisp files any more.
* src/lread.c (Fload): Use relative file names for `load-file-name`
when preloading for the dump, like we already did for `current-load-list`.

(scan_lisp_file): Remove functions, not used any more.
* doc/lispref/loading.texi (Library Search): Mention `lisp-directory`.

symbol and its 'err-conditions' and 'error-message' properties.

All callers changed.
Do not warn about timestamps like (1 . 1000). This warning was added
in Emacs 27 as a temporary transition aid, and has now served its
purpose. These timestamps, which Emacs 26 and earlier treated as (HI
. LO) instead of as (TICKS . HZ), were never generated by Emacs
primitives, and in practice the warning seems to have been triggered
only by test cases designed to generate it.
* src/timefns.c (WARN_OBSOLETE_TIMESTAMPS): Remove.
All uses changed to assume it’s false.
(decode_lisp_time): Simplify by taking a bool instead of an
integer bitmask. All uses changed.
