Summary:
When a block based table file is opened, if prefetch_index_and_filter is true, it will prefetch the index and filter blocks, putting them into the block cache.
What this feature adds: when a L0 block based table file is opened, if pin_l0_filter_and_index_blocks_in_cache is true in the options (and prefetch_index_and_filter is true), then the filter and index blocks aren't released back to the block cache at the end of BlockBasedTableReader::Open(). Instead the table reader takes ownership of them, hence pinning them, ie. the LRU cache will never push them out. Meanwhile in the table reader, further accesses will not hit the block cache, thus avoiding lock contention.
Test Plan:
'export TEST_TMPDIR=/dev/shm/ && DISABLE_JEMALLOC=1 OPT=-g make all valgrind_check -j32' is OK.
I didn't run the Java tests, I don't have Java set up on my devserver.

Summary:
In patch https://reviews.facebook.net/D47067, we change the
log level of the initial database information to header level.
As a result, even when the InfoLogLevel is set to Fatal, the
LOG file of a newly opened rocksdb instance will not be empty.
However, the current InfoLogLevelTest expect it should be empty.
This patch fixes this issue by enabling InfoLogLevelTest to
ignore the Log header.

Summary:
Whenever a Java class implements equals(), it has to implement hashCode(), otherwise
there might be weird behavior when inserting instances of the class in a hash map for
example. This adds two missing hashCode() implementations and extends tests to test
the hashCode() implementations.

While working on https://reviews.facebook.net/D43017 , I realized
that some Java tests are failing due to a deprecated option.
This patch removes the offending tests, adds @Deprecated annotations
to the Java interface and removes the corresponding functions in
rocksjni
Test Plan: make jtest (all tests are passing now)

Summary:
The option bottommost_level_compaction was introduced lately.
This option breaks the Java API behavior. To prevent the library
from doing so we set that option to a fixed value in Java.
In future we are going to remove that portion and replace the
hardcoded options using a more flexible way.
Fixed bug introduced by WriteBatchWithIndex Patch
Lately icanadi changed the behavior of WriteBatchWithIndex.

Summary:
In 3.10 the C++ code was extended with a MemEnv implementation. This
is now also available in RocksJava.
Changes:
- Extraced abstract super class Env
- Introduced RocksMemEnv
- Remove unnecessary disposeInternal method. The disposal of the default environment is managed by C++ so there needs to be no disposeInternal method in Java.
- Introduced a RocksMemEnvTest, which is aligned with the C++ equivalent.

Summary:
Before this change overflowing size_t values led to a checked Exception.
After that change:
size_t overflows on 32-Bit architecture throw now an IllegalArgumentException,
which removes the necessity for a developer to catch these Exceptions explicitly.
This is especially an advantage for developers targeting 64-Bit systems because
it is not necessary anymore to catch exceptions which are never thrown on a 64-Bit
system.
