document pointlist format
Teach crashlist about "Boss" directive in pointlists.

With this change, you can now make your pointlist like this:

    Boss,99:99/1
    Point,1,Test_Point_1,Test_Locale,Test_Sysop,0-000-000-0000,300,INA:localhost,IBN
made roundup part of the source distribution
make roundup path configurable
fix type mismatches and warnings through the code

This is a large set of patches that fixes:

- mismatches between format strings and variables
- 'char' where we meant 'int'
- 'unsigned char *' where we meant 'char *'
- 'long' where we meant 'uint32_t'

...and similar problems.

With this set of patches, Crashmail will now compile with
-Werror -Wall.
