Pieter Wuille bba89aa82a Pre-allocate block and undo files in chunks ...

Introduce a AllocateFileRange() function in util, which wipes or
at least allocates a given range of a file. It can be overriden
by more efficient OS-dependent versions if necessary.

Block and undo files are now allocated in chunks of 16 and 1 MiB,
respectively.
