initial commit for moving away from nqp

Note that this does not work at all yet.
fix loading of Perl5::Terms
fix parsing statements that include whitespace
make the status file that test_summary creates conditional

That means that we get a STATUS-{p|m|j}.md depending on the VM.
Also strip the nqp version line from the status file, we do not
use nqp anymore.
Whateverify negative array index
steal class Longname and sub dissect_longname from $*W
get us nearer to lax mode
use our own dissect_longname
one shall not use $Inf
fix integer literals and deprecated %h = {}
fix handling of infixes and literal numbers
fix ternary operator
fix parsing of pre- and postfixes
one step closer to package declarations
use nqplist helper sym
the things to bind must not match Any
wrap find_symbol to use nqplist
fix closures and reenable sink
can declare variables
fix assignment to just declared vars
