verify: add a config option to skip certain flag processors...

verify: add a config option to skip certain flag processors Previously, "hg verify" verifies everything, which could be undesirable when there are expensive flag processor contents. This patch adds a "verify.skipflags" developer config. A flag processor will be skipped if (flag & verify.skipflags) == 0. In the LFS usecase, that means "hg verify --config verify.skipflags=8192" will not download all LFS blobs, which could be too large to be stored locally. Note: "renamed" is also skipped since its default implementation may call filelog.data() which will trigger the flag processor.
