[PATCH 06/11] http*: move common variables and macros to http.[ch]

From: Tay Ray Chuan <hidden>
Date: 2016-06-15 22:46:47
Subsystem: the rest · Maintainer: Linus Torvalds

 *RANGE_HEADER_SIZE has been moved to http.h.

 *the curl header list, no_pragma_header, containing the header
  "Pragma:", has been created in http.[ch]. It is allocated in
  http_init, and freed in http_cleanup. It replaces the similarly-named
  variable in http-push.c, and the no_pragma_header member in
  walker_data in http-walker.c.

 *the variable http_is_verbose is created. It is intended for use by
  methods in http.c, and is modified at the entry points of http.c's
  users, namely http-push.c (when parsing options) and http-walker.c
  (in get_http_walker).
