Summary: This patch splits the posix storage backend into Env and
the actual *File implementations. The motivation is to allow other Envs
to use posix as a library. This enables a storage backend different from
posix to split its secondary storage between a normal file system
partition managed by posix, and it own media.
Test Plan: No new functionality is added to posix Env or the library,
thus the current tests should suffice.
Summary: Need to pass through the memtable parameter.
Test Plan: built, tested through myrocks

Test code errors are currently blocking Windows Release builew
We do not want spend time building in Release what we can not run
We want to eliminate a source of most frequent errors when people
check-in test only code which can not be built in Release.
This feature will work only if you invoke msbuild against rocksdb.sln
Invoking it against ALL_BUILD target will attempt to build everything.

Introduce new tags for records that have a log_number. This changes the
header size from 7 to 11 for these records, making this a
backward-incompatible change.
If we read a record that belongs to a different log_number (i.e., a
previous instantiation of this log file, before it was most recently
recycled), we return kOldRecord from ReadPhysicalRecord. ReadRecord
will translate this into a kEof or kBadRecord depending on what the
WAL recovery mode is.
We make several adjustments to the log_test.cc tests to compensate for the
fact that the header size varies between the two modes.

Summary: We don't yet have a CI build for iOS, so our iOS compile gets broken sometimes. Most of the errors are from assumption that size_t is 64-bit, while it's actually 32-bit on some (all?) iOS platforms. This diff fixes the compile.

Summary:
Give a name for every kill point, and allow users to disable some kill points based on prefixes. The kill points can be passed by db_stress through a command line paramter. This provides a way for users to boost the chance of triggering low frequency kill points
This allow follow up changes in crash test scripts to improve crash test coverage.
Test Plan:
Manually run db_stress with variable values of --kill_random_test and --kill_prefix_blacklist. Like this:
--kill_random_test=2 --kill_prefix_blacklist=Posix,WritableFileWriter::Append,WritableFileWriter::WriteBuffered,WritableFileWriter::Sync
