Fix faulthandler_suppress_crash_report() used to prevent core dump files
when testing crashes. getrlimit() returns zero on success.

When tk event handling is driven by IDLE's run loop, a confusing
and distracting queue.EMPTY traceback context is no longer added
to tk event exception tracebacks. The traceback is now the same
as when event handling is driven by user code. Patch based on
a suggestion by Serhiy Storchaka.

The original algorithm tried to delegate the folding to the tokens so
that those tokens whose folding rules differed could specify the
differences. However, this resulted in a lot of duplicated code because
most of the rules were the same.
The new algorithm moves all folding logic into a set of functions
external to the token classes, but puts the information about which
tokens can be folded in which ways on the tokens...with the exception of
mime-parameters, which are a special case (which was not even
implemented in the old folder).
This algorithm can still probably be improved and hopefully simplified
somewhat.
Note that some of the test expectations are changed. I believe the
changes are toward more desirable and consistent behavior: in general
when (re) folding a line the canonical version of the tokens is
generated, rather than preserving errors or extra whitespace.

Previously, CO_NOFREE was set in the compiler, which meant
it could end up being set incorrectly when code objects
were created directly. Setting it in the constructor based
on freevars and cellvars ensures it is always accurate,
regardless of how the code object is defined.

In _io_FileIO_readall_impl(), lseek() and _Py_fstat_noraise() were called
without releasing the GIL. This can cause all threads to hang for
unlimited time when calling FileIO.read() and the NFS server is not
accessible.

When PyGILState_Ensure() is called in a non-Python thread before
PyEval_InitThreads(), only call PyEval_InitThreads() after calling
PyThreadState_New() to fix a crash.
Add an unit test in test_embed.
Enhance also embedded tests, backport from master:
* Add test_pre_initialization_api()
* Set PYTHONIOENCODING environment variable in
test_forced_io_encoding()

* `make tags` fixes (GH-717)
* Fix `make tags` warnings
`make tags` target tries to find C sources and headers in "Grammar" and
"Mac" folders and generates these warnings:
ctags: Warning: cannot open source file "Grammar/*.[ch]" : No such file or directory
ctags: Warning: cannot open source file "Mac/*.[ch]" : No such file or directory
This commit changes $SRCDIRS variable in configure.ac to remote these
directories. This variable is used only for tags generation.
Also, "configure" was regenerated with `autoreconf`.
* Fix `make tags` fail on non-default tag names
When ctags overrides default tags filename (e.g. `-f .tags`) `make tags`
is failed because it assumes to see default `tags` filename:
sort: cannot read: tags: No such file or directory
This commit explicitly specifies "tags" filename for tags generation.
(cherry picked from commit 8a543c0bc7)
* make tags: index also Modules/_ctypes/ (#4648)
Avoid also "cd $(srcdir)" to not change the current directory.
(cherry picked from commit 3be3b97a97)
* Fixed saving bytearrays.
* Identical objects will be saved only once.
* Equal references will be load as identical objects.
* Added support for saving and loading recursive data structures.
(cherry picked from commit a897aeeef6)
* turtledemo: wait until macOS osascript command completes to not
create a zombie process
* Tools/scripts/treesync.py: declare 'default_answer' and
'create_files' as globals to modify them with the command line
arguments. Previously, -y, -n, -f and -a options had no effect.
