Summary:
In talbe.cc, when reading the metablock, it uses BytewiseComparator();
However in table_builder.cc, we use r->options.comparator. After tracing
the creation of r->options.comparator, I found this comparator is an
InternalKeyComparator, which wraps the user defined comparator(details
can be found in DBImpl::SanitizeOptions().
I encountered this problem when adding metadata about "bloom filter"
before. With different comparator, we may fail to do the binary sort.
Current code works well since there is only one entry in meta block.
Test Plan:
make all check
I've also tested this change in https://reviews.facebook.net/D8283 before.

Summary:
Change namespace from leveldb to rocksdb. This allows a single
application to link in open-source leveldb code as well as
rocksdb code into the same process.

- Replace raw slice comparison with a call to user comparator.
Added test for custom comparators.
- Fix end of namespace comments.
- Fixed bug in picking inputs for a level-0 compaction.
When finding overlapping files, the covered range may expand
as files are added to the input set. We now correctly expand
the range when this happens instead of continuing to use the
old range. For example, suppose L0 contains files with the
following ranges:
F1: a .. d
F2: c .. g
F3: f .. j
and the initial compaction target is F3. We used to search
for range f..j which yielded {F2,F3}. However we now expand
the range as soon as another file is added. In this case,
when F2 is added, we expand the range to c..j and restart the
search. That picks up file F1 as well.
This change fixes a bug related to deleted keys showing up
incorrectly after a compaction as described in Issue 44.
