Make bloom filters simpler

These did not work before, and had some unnecessary complexity.

Now the filters use only one hashing function, no bignum arithmetic, and gets the additional bit positions by repeatedly hashing the result of prior hash.

Since we're not concerned about crypto hashing here, this should be a win.

External interfaces unchanged.

The GOFLAGS variable makes it possible to run all sharness
tests with go binaries built with some special flags.

The "race" target makes it easy run the sharness tests
with go binaries built with the -race flag.

...and remove bin/* stuff from the .gitignore
as /test/bin is already in the root .gitignore.

This builds go binaries using the -race flag
and then runs all the tests.

This makes it possible to build binaries with
different flags.

The content of the GOFLAGS variable is stored
in a IPFS-BUILD-OPTIONS file, so that if GOFLAGS
changes a rebuild of the binaries with the new
flags is forced.

This script can be used in a Makefile to detect flag changes
and to save the new flags in a file.
