Dhruba Borthakur fe6119bd3a "make all check" fails
Summary:
If I run "make all check" it fails to build the leveldb-thrift-server tests. This is because the vanilla build is not supposed to build thrift and/or hdfs extensions. Remove the server test from auto-running.

The thrift/hdfs build instructions are more elaborate and I would like to avoid it for embedded database builds.

Test Plan: build and run

Dhruba Borthakur d11b637f34 bits_per_key is already configurable. It defines how many bloom bits will be used for every key in the database.
My change in this patch is to make the Hash code that is used for blooms to be confgurable. In fact,
one can specify a modified HashCode that inspects only parts of the Key to generate the Hash (used
by booms).

Sanjay Ghemawat 85584d497e Added bloom filter support.
In particular, we add a new FilterPolicy class.  An instance
of this class can be supplied in Options when opening a
database.  If supplied, the instance is used to generate
summaries of keys (e.g., a bloom filter) which are placed in
sstables.  These summaries are consulted by DB::Get() so we
can avoid reading sstable blocks that are guaranteed to not
contain the key we are looking for.

This change provides one implementation of FilterPolicy
based on bloom filters.

Other changes:
- Updated version number to 1.4.
- Some build tweaks.
- C binding for CompactRange.
- A few more benchmarks: deleteseq, deleterandom, readmissing, seekrandom.
- Minor .gitignore update.
