We will need the log number to validate the recycle-style CRCs. The log
is helpful for debugging, but optional, as not all callers have it.

When we recycle log files, we need to mix the log number into the CRC
for each record. Note that for logs that don't get recycled (like the
manifest), we always pass a log_number of 0 and false.

If log recycling is enabled, put old WAL files on a recycle queue instead of
deleting them. When we need a new log file, take a recycled file off the
list if one is available.

Add an environment method to reuse an existing file. Provide a generic
implementation that does a simple rename + open (writeable), and also a
posix variant that is more careful about error handling (if we fail to
open, do not rename, etc.).

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

This change will enable potential future optimizations but for now InternalIterator's functions are still the same as Iterator's.
At the same time, separate the cleanup function to a separate class and let both of InternalIterator and Iterator inherit from it.
