This makes no functional difference, but does tidy up the code style a
bit. All other internal headers are included using quotes in other
files.

Use `UINTPTR_MAX` to calculate the size of a pointer instead. This
assumes that all pointers are the same width.
It also means that the sysprof-capture code uses the pointer size of the
platform that libsysprof-capture was compiled on, rather than the
pointer size of the platform that GLib was compiled on. They seem
unlikely to differ.

This is more of a direct port than previous replacements of `GArray`
(which have had linear growth): this one implements exponential growth
of the allocated array, as `GArray` does.
It uses `qsort()` to sort the array so that it can be binary searched as
before.

There are typically 0 or 1 conditions applied to a cursor, and they’re
only applied at construction time, so it makes sense to only grow the
conditions array linearly when it’s used. This means the array may stay
as `NULL` throughout the lifetime of the cursor.
There’s currently no way to return an error from
`sysprof_capture_cursor_add_condition()`, so an allocation failure
results in an abort.

Use `strcmp()` and `strdup()` rather than `g_strcmp0()` and
`g_strdup()`. In the latter case, this makes no difference. In the
former case it means we potentially need to do some additional `NULL`
checks before calling it; although most of the call sites use
fixed-length arrays, so no `NULL` check is needed.

The code is well-suited to directly using `calloc()` instead, since the

Another step away from GLib. This changes the OOM behaviour of the
library — previously it would immediately `abort()` on OOM. However, it
seems likely that given the small number of allocations
libsysprof-capture does, it should be able to recover from an OOM
situation more gracefully than larger libraries can — so the new
implementation tries to do that.

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.
