Increase the default lock-stripe factor for PagedFiles

This reduces the lock contention on concurrent page faulting.
Load testing in realistic scenarios have shown that 256 locks are too few, and that 1024 is a lot better.
This increases the memory pressure that each mapped file puts on the system, so to counter this, the initial size of each map in the translation tables have been reduced from 32 to 8.

Increase the default lock-stripe factor for PagedFiles
Updated to a more recent version of IdMapper/StringEncoder/ParallelSort

and made some restructuring around how to calculate radix, since there are
two versions of it, one for longs and one for strings.
Also fixed an IntArray consurrency issue where multiple threads could
change the same underlying long, even if they were actually changing two
different nearby ints. So IntArray is now only an interface on top of
LongArray.
Removed auto-detection of long/string -> long id mapping

and instead provides user option to control that. "string" is always fine,
but an advanced user can provide "long" or "actual" for certain scenarios
for some gained performance.
