This is already supported by non Windows builds for libzip >= 1.3.1,
and since we're using at least libzip 1.4.0 on Windows, we should
support it there as well.
This causes a warning on GCC 9 and is unnecessary to boot: We
only use "cwd" for the open_basedir check, so we can just as well
pass in the original string.
`remove_path` points to the given string, so we must not modify it.
Instead we use a duplicate, if we need the modification.
We may want to switch to `zend_string`s in master.
The php_stream_read() and php_stream_write() functions now return
an ssize_t value, with negative results indicating failure. Functions
like fread() and fwrite() will return false in that case.
As a special case, EWOULDBLOCK and EAGAIN on non-blocking streams
should not be regarded as error conditions, and be reported as
successful zero-length reads/writes instead. The handling of EINTR
remains unclear and is internally inconsistent (e.g. some code-paths
will automatically retry on EINTR, while some won't).
I'm landing this now to make sure the stream wrapper ops API changes
make it into 7.4 -- however, if the user-facing changes turn out to
be problematic we have the option of clamping negative returns to
zero in php_stream_read() and php_stream_write() to restore the
old behavior in a relatively non-intrusive manner.
For two reasons: First, it's generally cheaper to match a regex than
perform a stat (especially on Windows). Second, it will not fail on
concurrent modification of a directory in parts that are not matched
by the pattern, such as the spurious failure in ext/zip/tests/bug72660.phpt.

And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
Normalization include:
- Use dnl for everything that can be ommitted when configure is built in
favor of the shell comment character # which is visible in the output.
- Line length normalized to 80 columns
- Dots for most of the one line sentences
- Macro definitions include similar pattern header comments now
