common/iobuf.h: Replace further use of literals with symbolic constants.

Browse source 
* common/iobuf.c: Move BLOCK_FILTER_INPUT,
BLOCK_FILTER_OUTPUT_BLOCK_FILTER_TEMP from here...
* common/iobuf.h: ... to here and rename to IOBUF_INPUT, IOBUF_OUTPUT
and IOBUF_TEMP, respectively.  Where appropriate, use these macros
instead of a literal.
