chgserver: spawn new process if schemes change
The schemes extension updates hg.schemes table. It's technically possible
for hg.repository() to look for e.g. ui.schemes instead of depending on
module-local table, but I don't think the change would make much sense
since [schemes] is usually specified in ~/.hgrc and thus it can be considered
static data.
