Joan Sala c196e8f054 omprog: add feedback timeout and keep-alive feature
Restart the program if it does not respond within timeout.
New setting 'confirmTimeout' (default 10 seconds).

Allow the program to provide keep-alive feedback when a
message requires long-running processing.

Improve efficiency when reading feedback line (use buffer).

Retry interrupted writes/reads to/from pipe.

New setting 'reportFailures' for reporting error messages
from the program.

Report child termination when writing to pipe.

Minor refactor: renamed writePipe function to sendMessage,
renamed readPipe to readStatus.
