Another step towards dropping GLib as a dependency of
libsysprof-capture.
Unlike the previous commit which replaced GLib integer types with the
bitwise equivalent C standard types, `stdbool` is potentially a different
width from `gboolean`, so this is an ABI break.
It therefore involves some changes to callback functions in the tests
and tools, and in libsysprof.

This is an almost entirely mechanical* conversion from (for example)
`gint` → `int`, `guint8` → `uint8_t`, etc.
It is not entirely complete, as many GLib functions are still used in
libsysprof-capture, which necessitate some use of GLib types.
It also avoids renaming `gboolean` → `bool` as that’s a slightly more
controversial change which will happen in the following commit.
*Code was manually realigned afterwards.

As preparation for dropping the GLib dependency from libsysprof-capture,
move the `GSource` which links a `MappedRingBuffer` to a `GMainContext`
from libsysprof-capture to libsysprof.
This requires adding one new piece of API to libsysprof-capture to check
whether the `MappedRingBuffer` is empty.

In preparation for dropping the GLib dependency from libsysprof-capture,
move the autocleanup definitions up to libsysprof. Add a new header for
them.
This is slightly awkward in the tools, which depend on
libsysprof-capture but not libsysprof. Rather than make them depend on
libsysprof (which might be disabled at configure time), include the
`sysprof-capture-autocleanups.h` file between source directories.
`SYSPROF_COMPILATION` needs to be defined for this to work.

It has previously been implicitly pulled in by libsysprof-capture, but
that will change in future.
Correspondingly, add some missing `glib.h` includes.

`reader` can be `NULL`, but the `NULL` check was done after potentially
dereferencing it.

Add a button to open capture files in headerbar. This caters to the
suggested usage of 'sysprof-cli' by exposing the funcitonality in a
prominent place.
This is a convenience function to call sysprof_collector_log() while also
formatting the message.
Ideally we'd be able to avoid the string format if we are not currently
collecting data, but that can be left for a future commit. We don't have
recursive locks so we need to duplicate the structure setup.

We can't get all the symbols here because of -Bsymbolic on the glib
library, but we can get the higher level bit. And if we're blocking for
a period of time, it can help track things down to know we block for
longer time periods.
The kernel symbol resolver requires access to sysprofd, which might not
be available in some contexts (such as when no polkit agent is available).
This allows that to continue working by disabling the kernel with the
user-only setting.
