libsysprof-capture: remove use of GAtomicRCBox

If we backport to an older GLib release, we won't have the newer atomic
helpers available. It's really not too much burden to do that manually if
it means we can run on older systems.

__sync_synchronize() to get the same effect, albeit slower.

libsysprof: add support for calculating temporary allocations
...
This is useful to find allocations free'd right after they were created.
A temporary allocation is currently defined as a free() right after an
allocation of that same memory address. From a quick glance, that appears
to be similar to what I've been seeing in heaptrack all these years.
In the long term, I'd expect we can do something more useful such as
"freed from similar stack trace" since things like g_strdup_printf()
would obviously break important temporary allocations.

preload: skip an additional stack frame

libsysprof: only add process cmdline info once
...
We might get this information from multiple sources (such as Linux's perf
or the proc data source). So only add this information once to avoid
having additional data we don't care about.
This also helps ensure we get a proper tree for the callgraph without
splitting things between updated cmdline information.

libsysprof-capture: allow for backtrace skip optimization

We want to be backtracing directly into the capture buffer, but also need
to skip a small number of frames.
If we call the backtrace before filling in information, we can capture to
the position *before* ev->addrs and then overwrite that data right after.

This seems to be significantly faster than doing the manual stepping. A
quick look shows that it has a number of special cases which we'd have
to duplicate, so best to just use it directly.

128 is a bit much and can slow us down considerably with user-space stack
