Summary:
When dynamically linking two binaries together, different builds of RocksDB from two sources might cause errors. To provide a tool for user to solve the problem, the RocksDB namespace is changed to a flag which can be overridden in build time.
Pull Request resolved: https://github.com/facebook/rocksdb/pull/6433
Test Plan: Build release, all and jtest. Try to build with ROCKSDB_NAMESPACE with another flag.

Summary:
Before this fix, the info_log_level passed from CreateLoggerFromOptions() will
be ignored by AutoRollLogger::logger_. This PR fixes it by setting the info log
level of logger_ during ResetLogger().

Summary:
AutoRollLogger sets GetStatus() to be non-OK if the log file fails to be created and logger_ is set to null. It is left to the caller to check the status before calling function to this class. There is no harm to create another null checking to logger_ before we using it, so that in case users mis-use the logger, they don't get a segfault.

Summary:
Right now, with auto roll logger, options.keep_log_file_num enforcement is triggered by events like DB reopen or full obsolete scan happens. In the mean time, the size and number of log files can grow without a limit. We put a stronger enforcement to the option, so that the number of log files can always under control.

Summary:
It is confusing to have auto_roll_logger to stay under db/, which has nothing to do with database. Move filename together as it is a dependency.

Summary:
There was a race condition in the test where the rolling thread
acquired the mutex before the flush thread pinned the logger. Rather than add
more complicated synchronization to fix it, I followed Siying's suggestion to
use SyncPoint in the test code.
Comments in the LoadDependency() invocation explain the reason for each of the
sync points.
Test Plan:
Ran test 1000 times for tsan/asan. Will wait for all sandcastle tests
to finish before committing since this is a tricky test.

Summary:
For GetLogFileSize() and Flush(), they previously did not follow the
synchronization pattern for accessing logger_. This meant ResetLogger() could
cause logger_ destruction while the unsynchronized functions were accessing it,
causing a segfault.
Also made the mutex instance variable mutable so we can preserve
GetLogFileSize()'s const-ness.
Test Plan:
new test case, it's quite ugly because both threads need to access
one of the functions with SyncPoints (PosixLogger::Flush()), and also special
handling is needed to prevent the mutex and sync points from conflicting.

* std::chrono does not provide enough granularity for microsecs and periodically emits
duplicates
* the bug is manifested in log rotation logic where we get duplicate
log file names and loose previous log content
* msvc does not imlement COW on std::strings adjusted the test to use
refs in the loops as auto does not retain ref info
* adjust auto_log rotation test with Windows specific command to remove
a folder. The test previously worked because we have unix utils installed
in house but this may not be the case for everyone.
Summary:
This change adds LogHeader provision to the logger. For the rolling logger
implementation, the headers are copied over to the new log file every time
there is a log roll over.
Test Plan: Added a unit test to test the rolling log case.

Summary:
We need to turn on -Wshorten-64-to-32 for mobile. See D1671432 (internal phabricator) for details.
This diff turns on the warning flag and fixes all the errors. There were also some interesting errors that I might call bugs, especially in plain table. Going forward, I think it makes sense to have this flag turned on and be very very careful when converting 64-bit to 32-bit variables.

Summary:
Currently, there is no easy way for user to change log level of info log. Add a parameter in options to specify that.
Also make the default level to INFO level. Removing the [INFO] tag if it is INFO level as I don't want to cause performance regression. (add [LOG] means another mem-copy and string formatting).
Test Plan:
make all check
manual check the levels work as expected.
