memprof: add memory profiling using LD_PRELOAD
...
This brings over some of the techniques from the old memprof design.
Sysprof and memprof shared a lot of code, so it is pretty natural to
bring back the same callgraph view based on memory allocations.
This reuses the StackStash just like it did in memprof. While it
would be nice to reuse some existing tools out there, the fit of
memprof with sysprof is so naturally aligned, it's not really a
big deal to bring back the LD_PRELOAD. The value really comes
from seeing all this stuff together instead of multiple apps.
There are plenty of things we can implement on top of this that
we are not doing yet such as temporary allocations, cross-thread
frees, graphing the heap, and graphing differences between the
heap at to points in time. I'd like all of these things, given
enough time to make them useful.
This is still a bit slow though due to the global lock we take
to access the writer. To improve the speed here we need to get
rid of that lock and head towards a design that allows a thread
to request a new writer from Sysprof and save it in TLS (to be
destroyed when the thread exits).

build: add datadir to pkgconfig files
...
Mutter wants sysprof's exact dbus interface directory during build time
* https://gitlab.gnome.org/GNOME/mutter/blob/master/src/meson.build#L714
On certain platforms mutter's datadir != sysprof's datadir.
This is initial work for a forthcoming PR to do
```
sysprof_dep.get_pkgconfig_variable('datadir')
```
in mutter for compatibility with these platforms.
This patch is on behalf of nixpkgs where we actually have to carry a
downstream patch [0] for this exact reason. We install everything into
their own immutable prefix under `/nix/store`.

libsysprof-capture: relicense as BSD-2-Clause-Patent

This allows embedding the static capture library without having to deal
with license incompatibility while retaining the patent clause. We want
as many consumers of the format as makes sense without the restriction
of what kind of app/library/tooling they are.
The application, sysprofd, libsysprof, and libsysprof-ui continue to be
GPLv3+.
