bugfix: fail to get the http request header by ngx.var. * (#1348)
* bugfix: to get the HTTP request header by `ngx.var.*`, we need to convert
  the name to lower case with dashes replaced by underscores.

more information:

http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_

* change: the key should be a string object when fetching a value from `ctx.var`.

* bug(make lint): If the code style is bad, do exit with code 1.
