608582d3c4 libsysprof-capture: Drop GLib dependency
None of the code uses it any more. This means that `libsysprof-capture.a`
can now be used within `libglib-2.0.so` for collecting main loop
statistics.

Brought to you by Opeth’s Deliverance on repeat.

41ec04ea99 libsysprof-capture: Replace G_BEGIN_DECLS with SYSPROF_BEGIN_DECLS
It does the same job, but doesn’t require GLib.

5636bbf4f0 libsysprof-capture: Use stdbool instead of gboolean
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.

2c2cbf6343 libsysprof-capture: Use C11 types instead of GLib types
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.

b449baa205 libsysprof-capture: Move MappedRingBufferSource to libsysprof
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.

69e4fb2588 libsysprof-capture: allow using ring in readwrite mode
This is a first step to be able to use the ring buffer as the backing
buffer for the SysprofCaptureWriter.

e3ed30eb48 libsysprof-capture: remove framing data from MappedRingBuffer
This removes the 8 bytes of framing data from the MappedRingBuffer which
means we can write more data without racing. But also this means that we
can eventually use the mapped ring buffer as our normal buffer for
capture writing (to be done later).

77400c57c1 libsysprof-capture: add mmap()'d ring buffer
This is the start of a ring buffer to coordinate between processes without
the overhead of writing directly to files within the inferior process.
Instead, the parent process can monitor the ring buffer for framing
information and pass that along to the capture writer.
