When called with an empty URI list (or only inaccessible files),
g_document_portal_add_documents would not call g_variant_builder_end,
leaking the memory allocated by the variant builder.

By removing the cached global proxy in gdocumentportal.c, we can
re-enable the checks for proper shutdown of the session bus connection
in the dbus-appinfo.c test.
Like for the OpenURI portal, O_PATH file descriptors do not prove access
to the underlying file data. I've used O_RDWR file descriptors here to
mirror the requested read/write permissions.
The g_auto macros are available only with GCC-compatible compilers on
Unix, but having __attribute__((cleanup)) is not part of our toolchain
requirements, so we shouldn't use it — even if we are building on
Unix-compatible systems.

Prevent the situation where errno is set by function A, then function B
is called (which is typically _(), but could be anything else) and it
overwrites errno, then errno is checked by the caller.
errno is a horrific API, and we need to be careful to save its value as
soon as a function call (which might set it) returns. i.e. Follow the
pattern:
int errsv, ret;
ret = some_call_which_might_set_errno ();
errsv = errno;
if (ret < 0)
puts (strerror (errsv));
This patch implements that pattern throughout GLib. There might be a few
places in the test code which still use errno directly. They should be
ported as necessary. It doesn’t modify all the call sites like this:
if (some_call_which_might_set_errno () && errno == ESOMETHING)
since the refactoring involved is probably more harmful than beneficial
there. It does, however, refactor other call sites regardless of whether
they were originally buggy.
