17355c3911 fix(preinit): scan multiple times the cmdline and rename altroot in rootalt 
The way the parsing works is examining one character at a time.

First, if we had `rootfstype=... root=...`, the parsing would jump and
ignore `root=...`, which sucks.

To fix this, we scan multiple times a copy of the cmdline.

Now, we have a new problem: `root=... altroot=...` lead to opts.device
being equal to the altroot as we are looking one char at a time, so we
will arrive at a moment looking at `root=...` for `altroot=...`.

To avoid this, we rename `altroot` in `rootalt`, cheap, I know.

86e81efbd6 tftp: introduce an alternative command line for TFTP 
Normal command line and TFTP command line can be sometimes very
different.

e.g. We don't want to load UBI filesystems for a TFTP boot as it may
interfere with our root device loading.

fad0a47b75 add config.system.callService 
this is like pkgs.callService except that it passes
config.system.service as a param so that the service
being defined can invoke other services

if this proves to be a good idea, all uses of
pkgs.callService should be changed to use it instead

MIPS_BOOTLOADER_CMDLINE_REQUIRE_COOKIE - local patch -
so that the bootloader args are ignored unless they
contain the string "liminix"
