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

Curl_poll() which is called whenever not a single valid file descriptor is
passed to these functions.

Improve readibility using a poll() macro to replace WSApoll().

Dependencies are now put in external file depend.dj.

CURL_DEBUG is defined.

  you can now use [1-1] without curl complaining.

it and avoid it, even if this cripples the CCC command

Added some more debug logs.

'crypto' tests aren't dependent on SSL.  Compiling with
--disable-crypto-auth will cause test failures, however.

libldap when available in liblber.

multi interface

  1) the progress callback gets called more frequently (at times)
  2) libcurl *might* call the callback when it receives a signal
