Fix bug in mt_mpmc.c, in Linux mutexes are not recursive.
Add arena_trim_string() to the arena API
Removing arena->path, now paths are pushed to arena->metadata
Replacing fe->owner[128] with char *owner; the owner is not pushed as a
string to arena->metadata and trimed with arena_trim_string()
Improving cache locality in arena->metadata, the memory layout is not
fe; fe->path; fe->owner.
Cache aligning all arenas except HasherContext->arena to sizeof(void *).
Pushing elements one by one instead of snprintf() in finalize_file() and
hash_worker().
Getting the full path of current directory instead of "."
Fixing bug in path formating, this allow us to remove normalize_path()
from the hot loop.
The windows implementation is disabled, currently registering files in
IO Ring when there is inflight IO operations causes corruptions.
Implementing a config file.
Some code cleanup
The IO Ring now supports bashing multiple submissions and can handle
multiple files at the same time.
Hashing small files using XXH3_128bits() instead of the streaming
pipeline(XXH3_128bits_reset(), XXH3_128bits_update(),
XXH3_128bits_digest()), this reduses the overhead of creating a state
and digest, coupled with the IO Ring it improves the hashing of small
files whose size is inferior to the size of IO Ring buffers
