Merge branch 'jh/resize-convert-scratch-buffer' 

When the "clean" filter can reduce the size of a huge file in the
working tree down to a small "token" (a la Git LFS), there is no
point in allocating a huge scratch area upfront, but the buffer is
sized based on the original file size.  The convert mechanism now
allocates very minimum and reallocates as it receives the output
from the clean filter process.

* jh/resize-convert-scratch-buffer:
  convert: avoid malloc of original file size
