introduce a new DBOption random_access_max_buffer_size to limit
the size of the random access buffer used for unbuffered access.
Implement read ahead buffering when enabled.
To that effect propagate compaction_readahead_size and the new option
to the env options to make it available for the implementation.
Add Hint() override so SetupForCompaction() call would call Hint()
readahead can now be setup from both Hint() and EnableReadAhead()

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.

We will need the log number to validate the recycle-style CRCs. The log

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

2. https://reviews.facebook.net/D48423 increased from 500 keys to 700 keys but in verification phase we are still querying the first 500 keys. It is a bug to fix.

Summary:
Separate a new class InternalIterator from class Iterator, when the look-up is done internally, which also means they operate on key with sequence ID and type.
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.
