e2fsprogs: add (optional) sparse checking to the build

Browse Source 
Run sparse against source files when building e2fsprogs with 'make C=1'.  If
instead C=2, it configures basic ext2 types for bitwise checking with sparse,
which can help find the (many many) spots where conversion errors are
(possibly) happening.
