downloadmonitoring-plugins-19bd8afa6b63dccadc2006292154f1633e2a29c9.tar.gz
some rework:
- added old style 'redir' function and options along to a new libcurl internal 'follow' parameter 'curl' - moved picohttpparser to it's own subdirectory - added uriparser to be used instead of the home-grown parser in 'redir'
