Summary: Currently the WAL file preallocation size is 1.1 * write_buffer_size. This, however, will be over-estimated if options.db_write_buffer_size or options.max_total_wal_size is set and is much smaller.
Test Plan: Add a unit test.

Summary:
Previously the sequence number was mistakenly passed in an argument
where the log number should go. This caused the reader to assume the old WAL

If log recycling is enabled with the rocksdb (recycle_log_file_num=16)
db->Writebatch is erroring out with keynotfound after ~5-6 hours of run
(1M seq but can happen to any workload I guess).See my detailed bug
report here (https://github.com/facebook/rocksdb/issues/1303).
This commit is the fix for this, a check is been added not to delete
the log file if it is already there in the recycle list.
Test Plan:
Unit tested it and ran the similar profile. Not reproducing anymore.
Summary: In ColumnFamilyTest.FlushCloseWALFiles, there is a small window in which the flush has finished but the log writer is not yet closed, causing the assert failure. Fix it by explicitly waiting the flush job to finish.
Test Plan: Run the test many times in high parallelism.
