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:
CreateLoggerFromOptions have some parameters like db_log_dir and env, these parameters are redundant since they already exist in DBOptions
this patch remove the redundant parameters and expose CreateLoggerFromOptions to users

* 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:
If auto roll logger can't create a new LOG file on roll (if, for example, somebody deletes rocksdb directory while rocksdb is running, khm), we'll try to call Logv on invalid address and get a SIGSEGV. This diff will fix the issue

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.

Summary:
There are three SanitizeOption-s now : one for DBOptions, one for ColumnFamilyOptions and one for Options (which just calls the other two)
I have also reshuffled some options -- table_cache options and info_log should live in DBOptions, for example.
Test Plan: make check doesn't complain

Summary:
PosixLogger and AutoRollLogger do not seem to be thread safe.
For PosixLogger, log_size_ is not atomically updated.
For AutoRollLogger, the underlying logger_ might be deleted by
one thread while still being accessed by another.

Summary:
* Add a SplitByTTLLogger to enable this feature. In this diff I implemented generalized AutoSplitLoggerBase class to simplify the
development of such classes.
* Refactor the existing AutoSplitLogger and fix several bugs.
Test Plan:
* Added a unit tests for different types of "auto splitable" loggers individually.
* Tested the composited logger which allows the log files to be splitted by both TTL and log size.
