Now that we are post-3.26, we are removing the legacy autotools
build system in favor of meson.
Please report any errors you have so that we can ensure this is
ready for GNOME 3.28.
This commit extends commit faf1e24edf
"zoom-manager: bring back attribute aligned(8)"
to both places where the attribute was previously dropped from
in commit 63579451b5 "alignment: set alignment on structs".
3.22.3 + commit 6a3d7282ec + commit faf1e24edf + this patch
has been successfully build tested on Debian armhf porterbox
(harris.debian.org). (It also means we end up with exactly
the same as the 3.22.2 + patch situation currently shipped
in Debian 'stretch' 9.0 regarding alignment/cast fixes.)

This was needed for some other architectures, even though it is problematic
that we have to do it (it should really be the default for the parent
GObject struct).
If we come across a map that is in another namespace, we might need to
translate it to the filesystem/path inside that mount namespace. Otherwise,
we won't be able to accurately decode ELF symbols due to loading the
incorrect binary/debug files.
This gives us the ability to locate symbols by directory in a much more
maintainable manner. Library consumers can adjust their location based
on where they know symbols are likely to be located.
This allows us to have a sysroot different than /, so that we can resolve
symbols that are not necessarily installed on the system. For example, if
we are running an application in an alternate mount namespace, we will want
to resolve the symbols starting from the location of the checkout for that
namespace.
Generally alternate mount namespaces will have paths like "/newroot/usr/.."
so by setting the source to "/newroot/usr/" to "~/.local/" you can do
some fancy remapping.
