BIT-1240: Fix MIME entity file data/gap ordering.

Browse source 
MIME entities buffered data and passed it along to protocol analyzers in
discrete amounts, but a gap is always passed along right away, so the
ordering of these "events" can cause incorrect file analysis.  The
change here is to never leave any MIME data buffered -- it should now be
passed along line by line as it is seen, but may still temporarily make
use of a buffer allocated by the analyzer as it works on decoding
content.
