Later GLib versions assume that warning C4715 is an error as we want ot
be sure that functions that return a value do indeed return one by all
means.
Avoid this warning by adding a 'return 0' in brz_search_packed(), it
might be pointless but does indeed avoid the warning.
...So that it will compile on non-C99 compilers. The changes are mainly
moving the variable declarations to the start of the resecptive blocks.
Also, replace the use of buflen in chd.c as it might not be defined for all
platforms, instead using packed_cr_size as it seems to represent the value
that is to be printed/displayed by the debugging output.

* Functions taking no parameters need to explicitly say (void).
* Mark some functions as static that are
* Comment out an unused function in bdz.c
* Change loop indicies "i" to be unsigned if our limit is unsigned
