e2lib: interrupt_hook: send interrupt to children

note interrupt_hook() no longer terminates e2factory

Signed-off-by: Tobias Ulmer <tu@emlix.com>

e2lib: add children_.. functions to track and terminate sub processes

If a child process has an associated pseudo terminal, it's terminated
via TIOCSIG ioctl, otherwise the standard kill() function is used.

Allows us to interrupt root-owned children (eg e2-su, sudo, ...)

Signed-off-by: Tobias Ulmer <tu@emlix.com>

Introduce build_set and result_build_set.

A build set contains a result build sets for each result we want to
build. The result build set contains all configurable settings, modes,
etc. on a per result basis.
This change disentangles all build specific parameters from the static
project configuration.

Signed-off-by: Tobias Ulmer <tu@emlix.com>

result: split build_config() into builtin_env()

Builtin env requires a BuildID, which in turn requires a fully set up
result with build modes etc. just to figure out the temporary directory.

Thus it makes sense to split build_config() into two methods operations,
with only builtin_env() requiring full setup work.
