[TableOptions/<FactoryClassName> "<ColumnFamily Name>"]
which includes information about its TableFactory class and belonging
column family. Below is an example TableOptions section of a
BlockBasedTableOptions that belongs to the default column family:
[TableOptions/BlockBasedTable "default"]

block_size_deviation=10
block_size=4096

Summary:
MyRocks reported some perfomance issues when inserting many keys into a transaction due to the cost of inserting new keys into WriteBatchWithIndex. Frequently, they don't even need the keys to be indexed as they don't need to read them back. DisableIndexing() can be used to avoid the cost of indexing.
I also plan on eventually investigating if we can improve WriteBatchWithIndex performance. But even if we improved the perf here, it is still beneficial to be able to disable the indexing all together for large transactions.

I see a lot of users compiling RocksDB with `make` or `make all` and then using those binaries in production. They end up running debug builds :(
This diff makes it harder for them:
1. I added an explicit warning to INSTALL.md
2. When you compile with `make all`, your resulting library will be librocksdb_debug.a
3. I also print out a warning when you compile in debug mode.
Hopefully should be enough :)

Since Andres' internship is over, I took over https://reviews.facebook.net/D42555 and rebased and simplified it a bit.
The behavior in this diff is a bit simpler than in D42555:
* only merge operators are passed through FilterMergeValue(). If fitler function returns true, the merge operator is ignored
* compaction filter is *not* called on: 1) results of merge operations and 2) base values that are getting merged with merge operands (the second case was also true in previous diff)
Do we also need a compaction filter to get called on merge results?

Summary:
The function GetBoundaryKeys() returns the smallest key from the first file and largest key from the last file. This is good for any level >0, but it's not correct for level 0. In level 0, files can overlap, so we need to check all files for boundary keys. This bug can cause wrong value for bottommost_level in compaction (value of true, although correct is false), which means we can set sequence numbers to 0 even if the key is not the oldest one in the database.
