  A left-over bug from the February 21 fix.

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.

more frequently allowing same calling frecuency for the client progress
callback, while keeping the once a second frecuency for speed calculations
and internal display of the transfer progress.

Added: Frequent calling of user progress callback

since that is the API yassl attempts to provide
