Summary: WritableFile::SetPreallocationBlockSize() requires parameter as size_t, and options used in DBImpl::GetWalPreallocateBlockSize() are all size_t. WritableFile::SetPreallocationBlockSize() should return size_t to avoid build break if size_t is not uint64_t.
Test Plan: Run existing tests.

Summary:
Many of our diffs dont have sandcastle tests because we failed to load arcanist token file (loaded over the network)
this diff try for at least 5 seconds (once every 0.2 second) to load the file instead of failing the first time the file is not found
This will make it less probable that diffs are submitted without sandcastle tests
Test Plan: arc diff --preview

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.

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.
