includes: remove curl/curlbuild.h and curl/curlrules.h

Rely entirely on curl/system.h now.

Introduced in Aug 2008 with commit 14240e9e109f. Now gone.

Fixes #1456

 NOTE FOR LIBCURL HACKERS
 
-The following notes apply to libcurl version 7.19.0 and later.
-
-* The distributed curl/curlbuild.h file is only intended to be used on systems
-  which can not run the also distributed configure script.
-
-* The distributed curlbuild.h file is generated as a copy of curlbuild.h.dist
-  when the libcurl source code distribution archive file is originally created.
-
 * If you check out from git on a non-configure platform, you must run the
-  appropriate buildconf* script to set up curlbuild.h and other local files
-  before being able of compiling the library.
-
-* On systems capable of running the configure script, the configure process
-  will overwrite the distributed include/curl/curlbuild.h file with one that
-  is suitable and specific to the library being configured and built, which
-  is generated from the include/curl/curlbuild.h.in template file.
-
-* If you intend to distribute an already compiled libcurl library you _MUST_
-  also distribute along with it the generated curl/curlbuild.h which has been
-  used to compile it. Otherwise the library will be of no use for the users of
-  the library that you have built. It is _your_ responsibility to provide this
-  file. No one at the curl project can know how you have built the library.
-
-* File curl/curlbuild.h includes platform and configuration dependent info,
-  and must not be modified by anyone. Configure script generates it for you.
+  appropriate buildconf* script to set up files before being able of compiling
+  the library.
 
 * We cannot assume anything else but very basic compiler features being
   present. While libcurl requires an ANSI C compiler to build, some of the

- * NOTE 1:
- * -------
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * curl library user nor by the curl library builder.
- *
- * If you think that something actually needs to be changed, adjusted
- * or fixed in this file, then, report it on the libcurl development
- * mailing list: https://cool.haxx.se/mailman/listinfo/curl-library/
- *
- * This header file shall only export symbols which are 'curl' or 'CURL'
- * prefixed, otherwise public name space would be polluted.
- *
- * NOTE 2:
- * -------
- *
- * Right now you might be staring at file include/curl/curlbuild.h.in or
- * at file include/curl/curlbuild.h, this is due to the following reason:
- *
- * On systems capable of running the configure script, the configure process
- * will overwrite the distributed include/curl/curlbuild.h file with one that
- * is suitable and specific to the library being configured and built, which
- * is generated from the include/curl/curlbuild.h.in template file.

-/* ================================================================ */

-/*
- * NOTE 1:
- * -------
- *
- * All checks done in this file are intentionally placed in a public
- * header file which is pulled by curl/curl.h when an application is
- * being built using an already built libcurl library. Additionally
- * this file is also included and used when building the library.
- *
- * If compilation fails on this file it is certainly sure that the
- * problem is elsewhere. It could be a problem in the curlbuild.h
- * header file, or simply that you are using different compilation
- * settings than those used to build the library.
- *
- * Nothing in this file is intended to be modified or adjusted by the
- * curl library user nor by the curl library builder.
- *
- * Do not deactivate any check, these are done to make sure that the
- * library is properly built and used.
- *
- * You can find further help on the libcurl development mailing list:
- * https://cool.haxx.se/mailman/listinfo/curl-library/
- *
- * NOTE 2
- * ------
- *
- * Some of the following compile time checks are based on the fact
- * that the dimension of a constant array can not be a negative one.
- * In this way if the compile time verification fails, the compilation
- * will fail issuing an error. The error description wording is compiler
- * dependent but it will be quite similar to one of the following:
- *
- *   "negative subscript or subscript is too large"
- *   "array must have at least one element"
- *   "-1 is an illegal array size"
- *   "size of array is negative"
- *
- * If you are building an application which tries to use an already
- * built libcurl library and you are getting this kind of errors on
- * this file, it is a clear indication that there is a mismatch between
- * how the library was built and how you are trying to use it for your
- * application. Your already compiled or binary library provider is the
- * only one who can give you the details you need to properly use it.
