[PATCH 0/3] commit-graph: introduce 'core.useBloomFilters'

Hi,

Here are some patches that we have been using at GitHub to control whether or not Bloom filters stored in commit-graphs are read during normal operation.

We're planning on using these patches as part of a two-phase roll-out of changed-path Bloom filters, where the first phase conditions whether or not repositories *write* Bloom filters, and the second phase (controlled via the new 'core.useBloomFilters') controls whether repositories *read* their Bloom filters.

This can also be handy for debugging purposes, say, for e.g., if Bloom filters are suspected to be corrupt, they can be softly disabled without dropping the rest of the data in the commit-graph.

Thanks in advance for your review.
