Optimization of libcurl usage (not releasing curl_handle at every request)

[stephanepiel]

Hello,

Here is an optimization I've made on this libcurl vmod. I've used the ability offered by libcurl to reuse a curl_handle for multiple requests. It allows to keep active connections, DNS cache, etc... , thus improving performances.
Tested/used with varnish 4.0.2

Hope you will find this helpful.
Regards,

Hi. Thanks for the patch. I've reviewed it and have some questions:
Is there any reason for restricting the number of reuses? Have you had any experience indicating this is needed and/or it could vary from place to place (i.e. why is configurable)?
Also is there any functional reason to move vmod_curl_list inside vmod_curl_priv?
It's better to address different concerns in separate PR as it makes reviewing them easier.
