SELinux has used 'char *' in place of its typedef
'security_context_t' since 2014 (v2.3) because the latter was
inconvenient to use when paired with the 'const' qualifier. The
typedef has been kept around for compatibility with legacy callers,
but it is deprecated in SELinux v3.1. See the following URL for the

Make newer ElDoc versions are compatible with Emacs < 28

Don't needlessly request docs from ElDoc functions
Fixes: bug#42421
Do this conservatively for now: if the ElDoc helper buffer (as
returned by eldoc--doc-buffer) is visible and showing documentation
for the very same "situation" (as computed by the the new
eldoc--request-state helper), don't request that documentation from
sources again.
Before this change, not only was that request inefficient but if the
user invoked scroll-other-window to see more of the helper buffer,
that would eventually cause it to be reformatted and unexpectedly
recentered.
Later on, when a customizable list of documentation "sinks" is offered
to the user, say, something like eldoc-display-functions, this process
must be consolidated. In those circumstances, as soon as one of those
sinks signals that it doesn't have up-to-date documentation for the
state computed by eldoc--request-state, documentation will have to be
requested anew from eldoc-documentation-functions via
eldoc--invoke-strategy.
