  A left-over bug from the February 21 fix.

one over to KNOWN_BUGS

test case 288 to verify it.

before resorting to the kill -9 hammer.

Added test harness infrastructure to support scp/sftp tests, using
OpenSSH as the server.

plus made --pass work on an SSH private key as well.

Shave off a couple of function calls in the part of
Curl_pgrsUpdate() which is always executed when called.

Fix a couple of comments.

For completeness sake, wait_ms() might also get interrupted when
experimental CURL_ACKNOWLEDGE_EINTR is defined.

or Curl_poll() with a non-zero timeout both functions would restart the
specified timeout. This could even lead to the extreme case that if a
signal arrived with a frecuency lower to the specified timeout neither
function would ever exit.

Added experimental symbol definition check CURL_ACKNOWLEDGE_EINTR in
Curl_select() and Curl_poll(). When compiled with CURL_ACKNOWLEDGE_EINTR
defined both functions will return as soon as a signal is caught. Use it
at your own risk, all calls to these functions in the library should be
revisited and checked before fully supporting this feature.
