Fix memory leak in output_file_close():
Arguable whose resposibility to free structs allocated inside a file
struct (the caller or the library function), but the following protocol
(i.e. this fix) would better prevent memory leaks:
1) output_file_close() function will free those structs inside a file struct,
right before closing the file.
* Note: those structs are originally allocated by other libsparse function.
2) If the caller wants to clean up those struct inside a file struct,
it may. Just free those structs, and set the pointer to NULL.
Afterward, when file_close()'s are called, they won't be free'ed twice.

this makes libsparse compile with MacOS clang++
Test: "libsparse" compiles and works fine under both Linux and MacOS

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
