  perl.h - add DEBUG_force() macro, to force debug for DEBUG_l() style macros

If you temporarily want to force on a DEBUG_l({...}) style macro you
have to change a fair bit of code, which is error prone. DEBUG_force()
lets you replace any DEBUG_x() macro with DEBUG_force() which will force
the debug block to execute (under DEBUGGING).

  Log Message:
  -----------
  cop.h - show a bit more debug out in JMPENV macros, and minor fixes

Eg, use (v) consistently. Line up backslashes. Show the return from
JMPENV_PUSH().

  Log Message:
  -----------
  perlinterp.pod - minor enhancements of the docs about JMPENV_ macros

Added a bit more on the levels and return codes. 1 is actually used
in the outmost call, or at least there is code to support it. Also
added "level" info, since that is used in -Dl.

  Log Message:
  -----------
  toke.c - dont just return the function, assign it to an intermediary

So we can debug it before we return. an optimization compiler should
make them the same thing anyway, but under -Og it is helpful to be able
to be able to see the return before we return it.

  Revert "postpone perl_parse() exit(0) bugfix"

This reverts commit 857320cbf85e762add18885ae8a197b5e0c21b69.

There were a lot of conflicts due to whitespace changes in the
intervening time. I manually reviewed the differences and merged them.

  Log Message:
  -----------
  pp_ctl.c - use try_yyparse() for eval

CATCH_GET is never true in this code, so we never called try_yyparse()
which in turn meant we leaked debug data from failed evals. With this
in place an eval that dies during compile will always be handled by
doeval_comp() properly.

This fixes GH Issue #20161.

  Log Message:
  -----------
  DRAFT: Stop parsing on first syntax error.

We try to keep parsing after many types of errors, up to a (current)
maximum of 10 errors. Continuing after a semantic error (like
undeclared variables) can be helpful, for instance showing a set of
common errors, but continuing after a syntax error isn't helpful
most of the time and will produce sometimes completely bizarre errors
which just obscure the actual error most of the time.

This patch makes the parser stop after the first syntax error, while
preserving the current behavior for other errors. An error is considered
a syntax error if the error message from our internals is the literal
text "syntax error". This may not be a complete list of true syntax
errors, we can iterate on that in the future.

Note that this patch relies on the fix "pp_ctl.c - use try_yyparse() for
eval", which allows t/comp/retainedlines.t to pass.
