downloadmonitoring-plugins-a739a5614834178ba88d04972b4f4ba9c560e1df.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'
