e8d02c50d7 libsparse: Fix overflow of merged sparse chunk length
Merging sparse chunk can make sparse map block bigger than 4GiB,
that can't be covered by unsigned integer type. Fix this by
changing unsigned int to uint64_t type.

Test: sparse build

db69f0d47f libsparse: Add sparse typed callback
Currently, sparse_file_callback uses libsparse's
own logic for reading a file into a buffer. However,
a caller may want to use their own logic for doing
this in order to customize the buffer size and parallelize
the reads/writes. Also, a caller may want to implement
fill blocks with their own logic as well. To do this
add sparse_file_typed_callback which calls a different
callback function depending on the type of the sparse
chunk being written.

Test: Use typed callback for fd writes
