[Chicken-hackers] define-record, etc. patch to chicken 4

[Jim Ursetto]

define-record, define-record-type and define-record-printer do not
take the module namespace into account, so records that are defined in
different modules--but have the same base name--may conflict, giving
strange results or crashing your program.  The attached patch
qualifies the structure name with the current module name, which seems
to work.

I also provided some REPL output (record-repl.scm) and a compilable
program (record.scm) which will demonstrate the before and after.

If this approach looks good, there are a few eggs which should be
examined because they create structures directly:

records: can be changed to use define-record
unix-sockets: same
datatype: should qualify symbols itself, if desired
easyffi: not sure
numbers: "compnum" unlikely to conflict, but could be qualified
