tests: factor out terminal handling from t7006 Other tests besides the pager ones may want to check how we handle output to a terminal. This patch makes the code reusable.

test_terminal: ensure redirections work reliably For terminal tests that capture output/stderr, the TTY prerequisite warning does not quite work for commands like test_terminal foo >out 2>err because the warning gets "swallowed" up by the redirection that's supposed only to be done by the subcommand. Even worse, the outcome depends on whether stdout was already a terminal (in which case test_terminal is a noop) or not (in which case test_terminal introduces a pseudo-tty in the middle of the pipeline). $ test_terminal.perl sh -c 'test -t 1 && echo >&2 YES' >out YES $ sh -c 'test -t 1 && echo >&2 YES' >out $ So: - use the test_terminal script even when running with "-v". - skip tests that require a terminal when the test_terminal script is unusable because IO::Pty is not installed. - write the "need to declare TTY prerequisite" message to fd 4, where it will be printed when running tests with -v, rather than being swallowed up by an unrelated redireciton.

tests: test terminal output to both stdout and stderr Some outputs (like the pager) care whether stdout is a terminal. Others (like progress meters) care about stderr. This patch sets up both. Technically speaking, we could go further and set up just one (because either the other goes to a terminal, or because our tests are only interested in one). This patch does both to keep the interface to lib-terminal simple.
