Use the fallback logic to generate the base path for the GtkAtSpiRoot
if the GApplication has no DBus object path to guarantee that
the base path will not stay NULL.
`gtk_at_spi_cache_add_context()` checks if the GtkAtSpiContext's path
is NULL before inserting the context object into the hash table.
Do the same in `gtk_at_spi_cache_remove_context()` to avoid a NULL
pointer dereference in `g_str_hash()` during the hash table lookup
if a context with NULL path is removed. That can happen when the
GtkAtSpiRoot::base_path is NULL, which, in turn, can happen if
`g_application_get_dbus_object_path()` returns NULL.

The _gtk_file_system_model_update_file() function is not used outside
GtkFileSystemModel, so no need to expose it in the header.
Shuffle it around in code, and remove it from the header.
The marked days are set only as part of gtk_calendar_select_day().
This is insufficient, especially because the day-selected signal
is emitted after the marked days are set in gtk_calendar_select_day().
The marked day gets applied to the current month, and either the previous
or subsequent month if they are visible within the current month.
This doesn't make any sense and likely was an accidental regression
in a6f9052cf1. Clarify the docs.
As part of a6f9052cf1, marked days lost
their style, essentially making that function worthless. Previously,
they were simply bolded, but that doesn't give them proper justice.
This issues a warning when an enum value is compared to a value that is
out of range for the enum.
We do this a lot, either when using -1 for undefined values or when
comparing array sizes to enum values like so:
enum {
ONE,
TWO,
THREE
} some_enum_value;
const char *names= { "one", "two", "three" };
g_assert (some_enum_value < G_N_ELEMENTS (names));
