This disables build-args support, which is nice when building things
on e.g. a shared build-machine, where we don't want the build to
be able to break out of the sandbox (by specifying e.g. --share=network).
This replaces all current callers of gs_file_ensure_directory with
equivalent code.
Actually, two instances were calling gs_file_ensure_directory with
FALSE, i.e. error out on EEXIST, but those cases seem fine with the
do-nothing-if-exists semantics.
We were not doing what the comments said we should, and we also
want to change what happens in the case of an old py file from
a previous layer (such as a base layer in a runtime) has a non-rewritten
.pyc file. In that case we want to assume its correct and fix it up.
If a .py file changes multiple times we can end up in a situation
where there is an .py file with corresponding .pyc file that we
rewrote, so both are now mtime==1. Then a new version of the .py file
is added, but the corresponding .pyc file is not updated. This means
that the .pyc file is stale, and python would not normally use it.
However, we will later change the mtime on the .py file to 1, causing
the old .pyo file to look up-to-date even though its stale.
We fix this by detecting the case where the is a new mtime on a .py file
where the .pyc file doesn't match, and remove the stale .pyc file.
Sprinkle g_prefix_error calls in builder-module.c, to make
sure that module-specific errors get a "module foo:" prefix.
This is not quite perfect, since callers tend to impose their
own prefix as well, but at least it clearly identifies the
module in which the error ocurred.
Putting spaces or slashes in module names is a recipe for
cryptic error from one of the many constructed flatpak
commandlines. Better warn early on, as soon as we see such
a name.
The configure arguments are now a combination of the
default config-opts plus the accumulative sum of the config-opts
specified in the build-options that are active for a given build
context.

I.e. instead of .xdg-app-builder/build-foo it will be
.xdg-app-builder/build/foo. This makes it easier to separate these
out, and it allows you to symlink this directory to /run/build to pick
up all sources when you use --keep-build-dirs.
