[PATCH v5 0/1] http: add support selecting http version




Normally, git doesn't need to set curl to select the HTTP version, it works
fine without HTTP/2. Adding HTTP/2 support is a icing on the cake.

This patch support force enable HTTP/2 or HTTP/1.1. 

example: 

GIT_CURL_VERBOSE=1 git2 -c http.version=HTTP/2 ls-remote https://bitbucket.org/aquariusjay/deeplab-public-ver2.git
