Add support for compressed PDF streams, using Simon's new deflate library.

# Halibut master makefile

# Currently depends on gcc, because:
#  - the dependency tracking uses -MD in order to avoid needing an
#    explicit `make depend' step
#  - the definition of CFLAGS includes the gcc-specific flag
#    `-Wall'
#
# Currently depends on GNU make, because:
#  - the Makefile uses GNU ifdef / ifndef commands and GNU make `%'
#    pattern rules
#  - we use .PHONY
