Summary:
I set up a mirror of our Java deps on github so we can download
them through github URLs rather than maven.org, which is proving
terribly unreliable from Travis builds.
Also sanitized calls to curl, so they are easier to read and
appropriately fail on download failure.

Summary:
Remove disableDataSync, and another similarly named disable_data_sync options.
This is being done to simplify options, and also because the performance gains of this feature can be achieved by other methods.

Summary:
That way we can see when this graph goes up and be happy.
Couple of changes:
1. title
2. fix db_bench to delete column families before deleting the DB. this was asserting when compiled in debug mode
3. don't sync manifest when disableDataSync. We discussed this offline. I can move it to separate diff if you'd like

Summary:
As discussed in our internal group, we don't get much use of seek compaction at the moment, while it's making code more complicated and slower in some cases.
This diff removes seek compaction and (hopefully) all code that was introduced to support seek compaction.
There is one test case that relied on didIO information. I'll try to find another way to implement it.

Summary:
Added an option for readrandom benchmark to run with tailing iterator instead of Get. Benefit of tailing iterator is that it doesn't require locking DB mutex on access.
I also have some results when running on my machine. The results highly depend on number of cache shards. With our current benchmark setting of 4 table cache shards and 6 block cache shards, I don't see much improvements of using tailing iterator. In that case, we're probably seeing cache mutex contention.
Here are the results for different number of shards
cache shards tailing iterator get
6 1.38M 1.16M
10 1.58M 1.15M
As soon as we get rid of cache mutex contention, we're seeing big improvements in using tailing iterator vs. ordinary get.

Changed block cache shards from 16 to 64, as Mark found that cache mutex contention is a big bottleneck.

Summary: @MarkCallaghan's tests indicate that performance with 8k rows in memtable is much worse than empty memtable. I wanted to add a regression tests that measures this effect, so we could optimize it. However, current config shows 634461 QPS on my devbox. Mark, any idea why this is so much faster than your measurements?
Test Plan: Ran the regression test.

Branch detection did not work in Jenkins. I realized that it set
GIT_BRANCH env variable to point to the current branch, so let's try
using this for branch detection.
Summary: When running regression tests on other branches, this will push values to entity rocksdb_build.$git_branch
Test Plan: Ran regression test on regression branch, observed values send to ODS in entity rocksdb_build.regression

Ran make in several modes;

* Report is available in html form (done in this diff, but need some extra work to integrate it in Jenkin)

Summary:
Several fixes:
1) Use mktemp to create the files and directories
2) Take the stat file as an argument so that the buildservers
can specify a file in the WORKSPACE and not in /tmp
3) Use nproc to set make -j value.
4) Check for valid values before sending to ODS
5) Cleanup the grep/cut pipeline to just use awk
