chunk: Externalize error reporting in chunk_write()
...
This avoids passing that arbitrary label just for error messages, and gives
greater flexibility in handling errors.

chunk: Use dynamically allocated buffer in chunk_from_fd()
...
When acting on files, we can use fstat() to estimate the buffer size. On
non-file FDs, we dynamically increase an allocated buffer.
Additionally we slightly change the function signature to properly handle
zero-length files and add appropriate unit tests.

chunk: Add predictable hash function
...
Since chunk_hash() is randomized its output is not predictable, that is,
it is only within the same process.

Randomly allocate chunk_hash() key during first use
...
This avoids hash flooding attacks.

Replace chunk_hash() with output from chunk_mac()
...
The quality is way better, the calculation is a bit slower though.
The key is statically initialized to zero, which will be changed later
to prevent hash flooding.
