Mark Mentovai aa2bc55777 posix: Allow ScopedMmap::ResetAddrLen() to deal with overlap
It should be possible to shrink a region already supervised by
ScopedMmap, or in rare cases when ScopedMmap is supervising only a
smaller portion of an overall larger region, increase the size of the
region it supervises. This is now equivalent to the operation of
base::mac::ScopedMachVM::reset().

The Reset() and ResetAddrLen() methods are upgraded from a void return
to a bool return to indicate their success.

Bug: crashpad:30
Test: crashpad_util_test ScopedMmap*.ResetAddrLen_*
