Subject: [archiso] Add archiso_pxe_curl hook

Its add support for downloading the ISO image via HTTP/FTP with curl or download *.sfs files.
The files are downloaded on /run/archiso/curlspace (tmpfs) and setup a loop dev from it
(like in archiso_loop_mnt) in the ISO case, or just do a bind mount to
/run/archiso/bootmnt in the other case.

This hook must be located after archiso_pxe_nbd in mkinitcpio.conf, in that way
NBD is the default.

New bootparm:
* archiso_curl_url=(first form)
    archiso_curl_url=http://192.168.0.7/archlinux/iso/archlinux.iso (absolute form)
        Use an absolute URL. Fetch the entire ISO
    archiso_curl_url=ftp://${pxeserver}/archlinux/iso/archlinux.iso (relative form)
        Use the as IP the same server where PXE reside.  Fetch the entire ISO

* archiso_curl_url=(second form)
    archiso_curl_url=http://192.168.0.7/archlinux/iso/unpacked (absolute form)
        Use an absolute URL. Where unpacked (an example name) is a directory where
        ${archisobasedir} ("arch" by default) is located with all *.sfs.
        This fetch only needed files.
    archiso_curl_url=ftp://${pxeserver}/archlinux/iso/unpacked (relative form)
        Use the as IP the same server where PXE reside. Where unpacked (an example name)
        is a directory where ${archisobasedir} ("arch" by default)
        is located with all *.sfs. This fetch only needed files.

* curlspace_size= Set a size for a tmpfs filesystem where files are downloaded.
