Summary: A bug in MockEnv causes fault_injestion_test to fail. I don't know why it doesn't fail every time but it doesn't seem to be right.
Test Plan:
Run fault_injestion_test
Also run db_test with MEM_ENV=1 until the first failure.

Summary: Add a new test case in fault_injection_test, which covers parallel compactions and multiple levels. Use MockEnv to run the new test case to speed it up. Improve MockEnv to avoid DestoryDB(), previously failed when deleting lock files.
Test Plan: Run ./fault_injection_test, including valgrind

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:
TestMemEnv simulates all Env APIs using in-memory data structures.
We can use it to speed up db_test run, which is now reduced ~7mins when it is
enabled.
We can also add features to simulate power/disk failures in the next
step
TestMemEnv is derived from helper/mem_env
mem_env can not be used for rocksdb since some of its APIs do not give
the same results as env_posix. And its file read/write is not thread safe
Test Plan:
make all -j32
./db_test
./env_mem_test
