This shouldn’t affect them (since it just adds the `clang-format-7`
package), but it’s good to keep everything on the same version.

Now we're returning the file type again, we need to mask it out to
compare with the mode. We can also check that the statbuf said the file
is a regular file.

This reverts commit bfdc5fc4fc.
This changes the semantics of G_FILE_ATTRIBUTE_ID_UNIX_MODE, and we've
already found one user of the previous semantics (ostree).
Closes#1934
In C, the proper type for a heap allocate structure is size_t/gsize.
That means, no valid (heap allocated) pointer will ever contain more
bytes than size_t can represent.
Hence, this integer type should also be used when operating on
data like a strv array. Adjust some internal uses to use gsize
instead of gint/guint.
Note that g_strv_length() returns a value of type guint. So this
API cannot be used on string arrays longer of arbitrary size. But
that is not fixable.
This reverts commit fd3ed5e31b.
C11-style atomics have been fixed (on FreeBSD and other platforms) in
the previous commit, “gatomic: Check argument width in
g_atomic_pointer_compare_and_exchange()”.
See !1229 and #1940.
Check that the new value is actually pointer-width, rather than (for
example) `sizeof (int)` which could happen if someone used `0` rather
than `NULL`.
Changes suggested by Simon McVittie.

Don’t pass integers; it’s not type-safe. The macro version of
`g_atomic_pointer_compare_and_exchange()` used to erroneously accept
integers, but they would have the wrong width on some platforms.

This function has numerous undocumented limitations. In particular, it
is not possible to ensure this function actually does anything. Document
these problems.
For many years after SSL 3.0 support was removed, we used this function
to indicate that we should perform protocol version fallback to the
lowest-supported protocol version, to workaround protocol version
intolerance. Nowadays this is no longer needed, and support has been
removed from glib-networking, so update the documentation.
GTlsConnection:rehandshake-mode has been deprecated since 2.60 using
the G_PARAM_DEPRECATED flag, but I forgot to add the right annotation to
the documentation. Oops.
The associated getter/setter functions were both deprecated properly.
This is the analogue of commit 7c4e6e9fbe, but applied to the
`GDBusMessage` parser, which does its own top-level parsing of the
variant format in D-Bus messages.
Previously, this code allowed arbitrary recursion of variant containers,
which could lead to a stack overflow. Now, that recursion is limited to
64 levels, as per the D-Bus specification:

This will allow subsequent testing of property name canonicalisation.
This test introduces no functional changes.

Helps: #358
Rather than adding a canonicalised and non-canonicalised version of the
signal to `g_signal_key_bsa`, just add the canonicalised version. Signal
lookups always use the canonicalised key (since the previous commit).
This saves space in `g_signal_key_bsa`, which should speed up lookups;
and it saves significant space in the global `GQuark` table (a 9.6%
reduction in entries in that table, by a rough test using
gnome-software).
We have to be a little more relaxed on the signal name validation than
we are for property name validation, as GTK installs a
`-gtk-private-changed` signal which violates the signal naming rules.

Previously, we’d look up the signal name as passed to (for example)
`g_signal_lookup()`, and rely on the fact that signals are inserted
twice into `g_signal_key_bsa`; once in canonical form and once not.
In preparation for only inserting signals into `g_signal_key_bsa` once,
we now try looking up a signal with the given signal name and, if that
fails, try canonicalising the name and trying again.
This is a performance hit on lookups for non-canonical names, but
shouldn’t affect the performance of lookups for canonical names. If
people want performance, they should use canonical names.

Since signal names are the same as property names, reference between the

Interned strings are never freed, so we don’t need to take a copy of

Rather than interning a property name string which isn’t canonicalised,
canonicalise it first, and enforce stricter validation on inputs.
The previous code was not incorrect (since the property machinery would
have canonicalised the property names itself, internally), but would
have resulted in non-canonical property names getting into the GQuark
table unnecessarily. With the new code, the interned property names from
property installation time should be consistently reused.

Inline with the stricter version of the property naming rules from the
