buffer class that doesn't throw exceptions.
The new buffer class is pretty simple and relies on the MemoryAllocator class that I previously to back large
allocations with mapped files when memory is scarce. That reduced the number of crashes quite a bit but we
still crash on machines that are simply out of diskspace as well. So, the right thing to do is to expect and
handle failures which is what this cl is all about. What we should see once this has landed is that crash
dumps due to courgette running out of disk space should disappear from crash/ and instead we should see the
number of users that run into this particular problem in dashboards.
TEST=Courgette out-of-memory/out-of-diskspace errors should disappear from crash/

TEST=This should give us a clearer picture of what's going wrong in the recent courgette crashes.

This is to better handle low memory situations when applying a differential
patch to a large Chrome setup.
For reading input files, I'm also switching to using memory mapped files
instead of ReadFileToString to reduce the load on the heap.
TEST=courgette.exe should succeed in applying a patch between two
chrome 10.x archives on an XP machine with 180MB of physical memory and
no page file.
