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.
Changes originally investigated and suggested by Ting-Wei Lan.

Fixes: #1940
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.
They’re causing the CI to fail. While someone familiar with FreeBSD
investigates the failure, it’s easiest to disable all C11-style atomics
than add more preprocessor checks to only disable the atomics added in
!1123.
If nobody can fix the new C11-style atomics before the 2.64.0 release,
this commit should be reverted and a more comprehensive set of preprocessor
checks put in place to essentially revert !1123 for BSD only.

In glib/gutf8.c there was an UB in function g_utf8_find_prev_char when
p == str. In this case we substract one from p and now p points to a
location outside of the boundary of str. It's a UB by the standard.
Since this function are meant to be fast, we don't check the boundary
conditions.
Fix glib/tests/utf8-pointer test. It failed due to the UB described
above and aggressive optimisation when -O2 and LTO are enabled. Some
compilers (e.g. GCC with major version >= 8) create an optimised version
of g_utf8_find_prev_char with the first argument fixed and stored
somewhere else (with a different pointer). It can be solved with either
marking str as volatile or creating a copy of str in memory. We choose
the second approach since it's more explicit solution.
Add additional checks to glib/tests/utf8-pointer test.
Closes#1917
We cannot just call
G_PARAM_SPEC_GET_CLASS (pspec)->value_set_default (pspec, &dflt_value);
without initializing the GValue first. It would call
param_string_set_default(), which would set the pointer value
to a cloned string (which later never gets released, because
the GValue is not known to hold a string).

Commit 7678b107 seems to have left the GHashTable pretty printer with an
off-by-one error, skipping the first key it encounters and printing an
extra garbage key/value pair instead. This fixes that by moving an
increment to the end of a loop rather than the beginning.
