Willy Tarreau bc236ad133 CLEANUP: dynbuf: move the reserve and limit parsers to dynbuf.c 
I just added a new setting to set the number of reserved buffer, to
discover we already had one... Let's move the parsing of this keyword
(tune.buffers.reserve) and tune.buffers.limit to dynbuf.c where they
should be.
