Prevent handle used for LOG from being inherited by subprocesses 
I recently encountered a problem with this because Windows doesn't allow
files to be deleted when there's open handles to them.

Other files opened by leveldb are not affected because by and large they
are using CreateFileA, which does not allow inheritance when
lpSecurityAttributes is null (ref:
https://docs.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-createfilea)

However, fopen() _does_ allow inheritance, and it needs to be expressly
disabled.

13e3c4efc6 Fix compactions that could end up breaking a run of the same user 
key across multiple files.

As reported in Github issue #339, it is incorrect to split the
same user key across multiple compacted files since it causes
tombstones/newer-versions to be dropped, thereby exposing obsolete
data. There was a fix for #339, but it ended up not fully fixing
the problem. (It checked for boundary problems in the first level
being compacted, but not the second). This problem was revealed
by Github issue 887.

We now adjust boundaries to avoid splitting user keys in both the
first level and the second level.

8cce47e450 Optimize leveldb block seeks to utilize the current iterator location. 
This is beneficial when iterators are reused and seeks are not random
but increasing. It is additionally beneficial with larger block sizes and keys with common prefixes.

Add a benchmark "seekordered" to db_bench that reuses iterators across
increasing seeks.  Add support to the benchmark to count comparisons made and to support common key prefix length. Change benchmark random seeds to be reproducible for entire benchmark suite executions but unique for threads in different benchmarks runs.  This changes a benchmark suite of readrandom,seekrandom from having a 100% found ratio as previously it had the same seed used for fillrandom.

./db_bench --benchmarks=fillrandom,compact,seekordered --block_size=262144 --comparisons=1 --key_prefix=100

without this change (though with benchmark changes):
seekrandom   :      55.309 micros/op; (631820 of 1000000 found)
Comparisons: 27001049
seekordered  :       1.732 micros/op; (631882 of 1000000 found)
Comparisons: 26998402

with this change:
seekrandom   :      55.866 micros/op; (631820 of 1000000 found)
Comparisons: 26952143
seekordered  :       1.686 micros/op; (631882 of 1000000 found)
Comparisons: 25549369

For ordered seeking, this is a reduction of 5% comparisons and a 3% speedup. For random seeking (with single use iterators) the comparisons and speed are less than 1% and likely noise.
