a143ef9b38 Change namespace from leveldb to rocksdb
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.

Test Plan: compile rocksdb

42c109cc2e New ldb command to convert compaction style
Summary:
Add new command "change_compaction_style" to ldb tool. For
universal->level, it shows "nothing to do". For level->universal, it
compacts all files into a single one and moves the file to level 0.

Also add check for number of files at level 1+ when opening db with
universal compaction style.

Test Plan:
'make all check'. New unit test for internal convertion function. Also manully test various
cmd like:

./ldb change_compaction_style --old_compaction_style=0
--new_compaction_style=1 --db=/tmp/leveldbtest-3088/db_test

92ca816a60 [RocksDB] Support internal key/value dump for ldb
Summary: This diff added a command 'idump' to ldb tool, which dumps the internal key/value pairs. It could be useful for diagnosis and estimating the per user key 'overhead'. Also cleaned up the ldb code a bit where I touched.

Test Plan: make check; ldb idump

61f1baaedf Introducing timeranged scan, timeranged dump in ldb. Also the ability to count in time-batches during Dump
Summary:
Scan and Dump commands in ldb use iterator. We need to also print timestamp for ttl databases for debugging. For this I create a TtlIterator class pointer in these functions and assign it the value of Iterator pointer which actually points to t TtlIterator object, and access the new function ValueWithTS which can return TS also. Buckets feature for dump command: gives a count of different key-values in the specified time-range distributed across the time-range partitioned according to bucket-size. start_time and end_time are specified in unixtimestamp and bucket in seconds on the user-commandline
Have commented out 3 ines from ldb_test.py so that the test does not break right now. It breaks because timestamp is also printed now and I have to look at wildcards in python to compare properly.

Test Plan: python tools/ldb_test.py

8a48410f09 Enhance the ldb tool to support ttl databases
Summary: ldb works with raw data from the database and needs to be aware of ttl-database to work with it meaningfully. '-ttl' option now tells it that. Also added onto the ldb_test.py test. This option may be specified alongwith put, get, scan or dump. There is no support to provide a ttl-value and it uses default forever because there is no use-case for this currently.

Test Plan: make ldb_test; python tools/ldb_test.py
