…under free-threading (gh-151768) (gh-153789)

In free-threading builds, concurrent calls to sys.getdlopenflags() and
sys.setdlopenflags() race on interp->imports.dlopenflags.  Fix by
using FT_ATOMIC_LOAD_INT_RELAXED / FT_ATOMIC_STORE_INT_RELAXED in
_PyImport_GetDLOpenFlags and _PyImport_SetDLOpenFlags, consistent with
how analogous interpreter-state integer fields (lazy_imports_mode,
pystats_enabled) are protected.

Relaxed ordering is correct here: dlopenflags is a standalone config
integer with no ordering relationship to other memory.

gh-153926: Fix documented parameter name for calendar.calendar and calendar.prcal

calendar.calendar() and calendar.prcal() are bound methods of the
module's TextCalendar instance, whose first parameter is named theyear,
but the documentation named it year, so the documented keyword raised
TypeError. Update the documentation to match the real signature, which
also matches the sibling month() and prmonth() functions.
