chunk: Correctly parse Base64 text where four = follow in a row
...
That's not correct Base64 but invalid data could trigger this. Since
outlen would get reduced four times, but is only ever increased three
times per iteration, this could result in an integer underflow and then
a potential buffer overflow.

chunk: Fix internet checksum calculation on big-endian systems
...
ntohs() might be defined as noop (#define ntohs(x) (x)) so we have
to manually shorten the negated value (gets promoted to an int).
Fixes #747 .

unit-tests: Seed chunk_hash() only once, but before creating any hashtables
...
Due to the removal of pthread_once, we manually create the seed for
chunk_hash(). With the new testable functions interface, this won't work for
the hashtable initiated using __attribute__((constructor)). Enforce seeding
before creating that hashtable.

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.

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.
