Allow UseDelta option to specify a delta ratio
Rework the frontend and backend to allow passing a ratio value in for UseDelta rather than having a hardcoded #define-d 0.7 value always used. This is useful for those with fast connections, who would likely benefit from tuning this ratio to lower values; it is also useful for general testing purposes. The libalpm API changes for this, but we do support the old config file format with a no-value 'UseDelta' option; in this case we simply use the old default of 0.7. We clamp the ratio values to a sane range between 0.0 and 2.0, allowing ratios above 1.0 for testing purposes. Signed-off-by: Dan McGee <dan@archlinux.org>
