Martin Willi 460adb5d09 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.

Martin Willi 922ee2c529 windows: Add a common Windows header for platform specific wrappers
Include some more basic system headers in utils.h, so we can use that common
header on the different platforms.

Martin Willi b9ee059ca9 chunk: Externalize error reporting in chunk_write()
This avoids passing that arbitrary label just for error messages, and gives
greater flexibility in handling errors.

Martin Willi 1c4a3459f7 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.

Tobias Brunner 20a48e4be3 chunk: Fix signedness warnings caused by chunk_from_* macros
There are countless other such warnings because e.g. chunk_create() is called
with char*, but at least we prevent users from causing such warnings
inadvertently when using these macros.

Tobias Brunner ed235dbbf2 chunk: Add predictable hash function
Since chunk_hash() is randomized its output is not predictable, that is,
it is only within the same process.

Tobias Brunner c1be5d66cd Use local variable in chunk_from_str()
This allows using strdup() or other string functions as argument
without calling them twice.

Tobias Brunner d1953fe403 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.
