instead of having them "not implemented" (and consequently getting
errors), just let requires(), system(), mkpath(), write_file(), touch()
and cache() do nothing. this is likely to cause followup failures which
are harder to detect, but the amount of scary noise we are producing now
is not really acceptable. furthermore, in qtcreator these failures
actually terminate the "precise" evaluation, which breaks Run
Configurations.

the backslash still escapes only quotes (and itself) - $$list() (one of
the main users of this function) is commonly used with (windows) path
lists, so letting it escape anything would make a royal mess.

$$(FOO) would automatically split the contents of the environment
variable at whitespace (and interpret quoting inside it). the way to
prevent the splitting (but not the quote interpretation) would be using
"$$(FOO)".

this behavior is entirely unexpected and thus an incredibly effective
source of quoting problems - according to a grep over the whole qt
sources, there isn't a single case where things were done right. in qt
creator, well over half the cases are wrong.

also, the "feature" seems entirely pointless: nobody uses spaces as
separators in environment variables.

consequently, simply remove it, even in a patch release. i'm postulating
that nobody will complain.
