Hey! 

The patch below carries the fix for the failure on Big-endian architectures.
We now treat bloom filter data as a simple binary stream of 1 byte words 
instead of 8 byte words. This avoids the Big-endian vs Little-endian 
confusion on different CPU architectures. 

Here is the successful run of SZEDER's Travis CI s390x build. 

 https://travis-ci.org/szeder/git/jobs/649044879

I will be squashing this patch into the appropriate commits in the series
in v3, which I will send out after people have had a chance to complete
their review of v2. 

A special thanks to SZEDER for helping us test our patches on his CI 
pipeline and saving us the overhead of setting up a Big-endian machine!

Cheers!
Garima Singh

Subject: [PATCH] Process bloom filter data as 1 byte words

Process bloom filter data as 1 byte words instead of 8 byte
words to avoid the Big-endian vs Little-endian confusion on
different CPU architectures
