Summary: Fix for memory leaks in rocksdb tests. Also modified the variable NUM_FAILED_TESTS to print the actual number of failed tests.
Test Plan: make <test>; valgrind --leak-check=full ./<test>

Summary:
Add a shortcut function to make it easier for people
to efficiently bulk_load data into RocksDB.
Test Plan:
Tried ldb with "--bulk_load" and "--bulk_load --compact" and verified the outcome.
Needs to consult the team on how to test this automatically.

Summary:
Replace manual memory management with std::unique_ptr in a
number of places; not exhaustive, but this fixes a few leaks with file
handles as well as clarifies semantics of the ownership of file handles
with log classes.

Summary: The queries will come from stdin. One key per line. The output will be in stdout, in the format of "<key> ==> <value>" if found, or "<key>" if not found. "--hex" uses HEX-encoded keys and values in both input and output.

Summary: We were ignoring additional chars at the end of an arg. This can create confusion, e.g. --disable_wal=0 will act the same as --disable_wal without any warnings.
Test Plan:
Tried this:
[zshao@dev485 ~/git/rocksdb] ./ldb dump --statsAAA
Failed: Unknown argument:--statsAAA

Summary:
This allows ldb to control the write_buffer_size (which reflects to L0 file size) and file_size (which reflects to L1 file size). Since the target_file_size_ratio is 1 by default, all other levels will also have the same file size as L1.
As part of the diff, I also cleaned up some unused code and help messages.
Test Plan: ./ldb load --db=/data/users/zshao/test_leveldb --file_size=64000000 --write_buffer_size=32000000 --create_if_missing --input_hex --disable_wal

Summary: This command accepts key-value pairs from stdin with the same format of "ldb dump" command. This allows us to try out different compression algorithms/block sizes easily.

Test Plan:
Tried the following program:

printf("%X\n", c);

Summary:
Added the following two options:
[--bloom_bits=<int,e.g.:14>]
[--compression_type=<no|snappy|zlib|bzip2>]
These options will be used when ldb opens the leveldb database.
Test Plan: Tried by hand for both success and failure cases. We do need a test framework.

Summary:
It would appear our unit tests make use of code from ldb_cmd,
and don't always require a valid database handle. D6855 was not aware
db_ could sometimes be NULL for such commands, and so it broke
reduce_levels_test.
This moves the check elsewhere to (at least) fix the 'ldb dump' case of
segfaulting when it couldn't open a database.

I changed the reduce_num_levels logic to avoid "compactRange()" call if the current number of levels in use (levels that contain files) is smaller than the new num of levels.
And that change breaks the assert in reduce_levels_test
