Summary:
InfoLogLevel test now checks the number of lines of the output log file
instead of the number of bytes in the log file.
This diff fixes the issue that the previous InfoLogLevel test in
auto_roll_logger_test passed in make check but fails when valgrind
is used.
Test Plan: run with make check and valgrind.

Summary:
* Now each Log related function has a variant that takes an additional
argument indicating its log level, which is one of the following:
- DEBUG, INFO, WARN, ERROR, FATAL.
* To ensure backward-compatibility, old version Log functions are kept
unchanged.
* Logger now has a member variable indicating its log level. Any incoming
Log request which log level is lower than Logger's log level will not
be output.
* The output of the newer version Log will be prefixed by its log level.
Test Plan:
Add a LogType test in auto_roll_logger_test.cc
= Sample log output =

This is not a generic thread local implementation in the sense that it

Summary:
This will also help with avoiding the deadlock. If a flush failed and we're waiting for a memtable to be flushed, we should schedule a new flush and hope a new one succeedes.
If paranoid_checks = false, Wait() will still hang on ENOSPC, but at least it will automatically continue when the space frees up. Current behavior both hangs and deadlocks.
Also, I renamed some 'compaction' to 'flush'. 'compaction' was leveldb way of saying things.

If flush fails because of ENOSPC, we have a deadlock problem. This is a quick fix that will continue the normal operation when user deletes the file and frees up the space on the device.
We need to address the issue more broadly with bg_error_ cleanup.

Summary:
Previous our new `arc lint` has two annoying bugs:
* Keeping sending false alarm that we'd put c++ system files first -- even though we've already done that.
- this problem is caused by our linter, which doesn't give the underlying cpplint.py right file path (it gives "-" as file name), making cpplint.py work incorrectly.
* Only works in rocksdb's root dir; Otherwise it'll throw exception saying "cannot find cpplint.py".
I copied open source ArcanistCpplintLinter and modifiy it for our use.
Test Plan: Ran arc lint and made sure the above-mentioned problem won't occur.
