Using ``method`` markup because the method is on a callback object, not an

preexec_fn callback, which may open file descriptors.

Previously it generated them if they were given a value, but completely
ignored them if they were present in the string passed in to be parsed.  Now
if the flag appears on a cookie, the corresponding Morsel key will reference a
True value.  Other pre-existing behavior is retained in this maintenance
patch: if the source contains something like 'secure=foo', morsel['secure']
will return 'foo'.  Since such a value doesn't round trip and never did (and
would be a surprising occurrence) a subsequent non-bug-fix patch may change
this behavior.

Inspired by a patch from Julien Phalip, who reviewed this one.

With importlib getting used more and more, changing __import__ will
not work as well as people used to hope as it will potentially bypass
importers, etc. It also will not work with importlib.import_module()
as it uses "importlib.__import__" (i.e. importlib's implementation of
import) directly and not builtins.__import__.

This is needed for support Tcl/Tk 8.6.

fork() is suppose to be async-signal safe but the handler calls unsafe functions. A parent handler mitigates the issue.

This also backs out the previous fixes for for #14360, #1717, and #16564.
Those bugs were actually caused by the fact that set_payload didn't decode to
str, thus rendering the model inconsistent.  This fix does mean the data
processed by the encoder functions goes through an extra encode/decode cycle,
but it means the model is always consistent.  Future API updates will provide
a better way to encode payloads, which will bypass this minor de-optimization.
