60102016e4 Abolish max-specpdl-size (bug#57911)
The max-lisp-eval-depth limit is sufficient to prevent unbounded stack
growth including the specbind stack; simplify matters for the user by
not having them to worry about two different limits.  This change
turns max-specpdl-size into a harmless variable with no effects,
to keep existing code happy.

cba866599c Raise default max-specpdl-size and max-lisp-eval-depth
Recent changes have caused bootstrapping to fail for certain
configurations, and it was likely getting close to the limits
for others.  This change raises the limits to those previously
used when configured for nativecomp:

  max-specpdl-size raised from 1800 to 2500
  max-lisp-eval-depth raised from 800 to 1600

* src/eval.c (init_eval_once): Raise limits.
* doc/lispref/eval.texi (Eval):
* doc/lispref/variables.texi (Local Variables): Document new values.
