Summary: Make RocksDb build and run on Windows to be functionally
 complete and performant. All existing test cases run with no
 regressions. Performance numbers are in the pull-request.

 Test plan: make all of the existing unit tests pass, obtain perf numbers.

1369f015ee Only initialize the ThreadStatusData when necessary.
Summary:
Before this patch, any function call to ThreadStatusUtil might automatically initialize and register the thread status data.  However, if it is the user-thread making this call, the allocated thread-status-data will never be released as such threads are not managed by rocksdb.

In this patch, I remove the automatic-initialization part.  Thread-status data is only initialized and uninitialized in Env during the thread creation and destruction.

Test Plan:
db_test
thread_list_test
listener_test

fe5c6321cb Allow EventListener::OnCompactionCompleted to return CompactionJobStats.
Summary:
Allow EventListener::OnCompactionCompleted to return CompactionJobStats,
which contains useful information about a compaction.

Example CompactionJobStats returned by OnCompactionCompleted():
    smallest_output_key_prefix 05000000
    largest_output_key_prefix 06990000
    elapsed_time 42419
    num_input_records 300

    total_input_raw_value_bytes 300000
    num_records_replaced 100
    is_manual_compaction 1

Test Plan: Developed a mega test in db_test which covers 20 variables in CompactionJobStats.

77a5a543a5 Allow GetThreadList() to report basic compaction operation properties.
Summary:
Now we're able to show more details about a compaction in
GetThreadList() :)

This patch allows GetThreadList() to report basic compaction
operation properties.  Basic compaction properties include:
    1. job id
    2. compaction input / output level
    3. compaction property flags (is_manual, is_deletion, .. etc)
    4. total input bytes
    5. the number of bytes has been read currently.
    6. the number of bytes has been written currently.

Flush operation properties will be done in a seperate diff.

Test Plan:
/db_bench --threads=30 --num=1000000 --benchmarks=fillrandom --thread_status_per_interval=1

Sample output of tracking same job:

bf287b76e0 Add structures for exposing thread events and operations.
Summary:
Add structures for exposing events and operations.  Event describes
high-level action about a thread such as doing compaciton or
doing flush, while an operation describes lower-level action
of a thread such as reading / writing a SST table, waiting for
mutex.  Events and operations are designed to be independent.
One thread would typically involve in one event and one operation.

Code instrument will be in a separate diff.

Summary:

This patch moves GetThreadList() feature under Env to better manage the dependency of GetThreadList() feature
on thread creation and destruction.

Renamed ThreadStatusImpl to ThreadStatusUpdater.  Add ThreadStatusUtil, which is a static class contains
utility functions for ThreadStatusUpdater.

Test Plan: run db_test, thread_list_test and db_bench and verify the life cycle of Env and ThreadStatusUpdater is properly managed.
