Prevent the progressbar and status messages to mess up stdout.

to not run any per-package scripts. useful for managing buildroot
when cross-compiling.

add also a test case for this

at least debian and musl do this, so let's go along with that.

This option lets us search for all package with given origin.

apk would try run the trigger even if package failed to install.

We should not disqualify non-selectable packages as it would mark it as
dirty, forcing it to reconsider the name again, which could end up in
an endless loop.

fixes #2135

fixes #2134

musl does not have those.

for musl compatibility
