Add fuzzer for function JIT

This is a basic fuzzer for the function JIT, which looks for
crashes and sanitizer violations only, and does not try to detect
differing behavior yet.

Destroy file handle earlier in execute fuzzer

I'm not quite sure why this is relevant, but if matches what other
code does and fixes oss-fuzz #32517.

Free static variables in execute fuzzer

Fixes a leak in the seed corpus.

Change Zend Stream API to use zend_string* instead of char*.

This allows to eliminate re-calculation of string lenght and hash value.

Replace all usages with the standard bool type everywhere.

Disable InfiniteIterator class while fuzzing

The combination of LimitIterator and InfiniteIterator can cause
effectively infinite loops that bypass the executor step limit.

Extend function blacklist in execute fuzzer

Add pfsockopen and stream_socket_server.

Fix typo

This was supposed to include the header, not the C file...

Generate execute corpus in generate_all.php

And add crypt() to the function blacklist, it can be very slow.

Reduce oniguruma retry limit in fuzzer

Reduce the retry limit by another factor of 10 in hope of reducing

Limit max length for parser fuzzer

We're getting some very large inputs (~500KB) on OSS-Fuzz, which
slot down performance a lot. Let's try limiting this, starting
with a still fairly large value of 64KB.

Also remove the max_execution_time limit, so that slow test cases
cause a genuine libfuzzer timeout and we may investigate them.
