54ab0bd64c refactor: commit to 8 byte obfuscation keys
Since 31 byte xor-keys are not used in the codebase, using the common size (8 bytes) makes the benchmarks more realistic.

8bb34f07df Explicitly close all AutoFiles that have been written
There is no way to report a close error from `AutoFile` destructor.
Such an error could be serious if the file has been written to because
it may mean the file is now corrupted (same as if write fails).

So, change all users of `AutoFile` that use it to write data to
explicitly close the file and handle a possible error.

fab5cb9066 fuzz: Reduce LIMITED_WHILE limit for file fuzzing
A higher limit is not needed, and only leads to timeouts, see for
example the buffered_file one in

fa5388fad3 fuzz: Remove FuzzedAutoFileProvider
The code is clearer without it.

This is also needed for a future commit.

fa24493d63 Use spans of std::byte in serialize
This switches .read() and .write() to take spans of bytes.

214d9055ac fuzz: replace every fuzzer-controlled loop with a LIMITED_WHILE loop
Blindly chose a cap of 10000 iterations for every loop, except for
the two in script_ops.cpp and scriptnum_ops.cpp which appeared to
(sometimes) be deserializing individual bytes; capped those to one
million to ensure that sometimes we try working with massive scripts.

There was also one fuzzer-controlled loop in timedata.cpp which was
already capped, so I left that alone.

git grep 'while (fuzz' should now run clean except for timedata.cpp
