Remove HAVE_OCILOBISTEMPORARY and HAVE_OCICOLLASSIGN
Symbols are not used in the current code.
Also remove not needed ocijdbc8 library addition and checks whcih were
removed also via b8e1d4d4e5af74a9d5a95d03adbe2b93e58301b7 so Oracle 8
is no longer supported.
Report errors from stream read and write operations
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.

Prevent use after free in fpm_event_epoll_wait
epoll event backend does not guarantee that child input/output events
are reported before SIGCHILD due to finished worker. While a bunch of
events received by epoll is being processed, child-related structures
may be removed before dispatching of an I/O event for the same child.
The result may be attempt to access to memory region allocated for
another purpose, segfault of the master process, and unavailable web
sites.
Postpone processing of SIGCHILD events till other events in the same
bunch are processed.

Remove build.mk usage
First step when creating the `configure` script is currently using
make. This is helpful when developing buildsystem to only rebuild
`configure` and `main/php_config.h.in` files when one of the *.m4
or configure.ac file changes and saves the developer time a little.
Realistically however, it is not needed that much considering the
times of several seconds to fully rebuild the configure script and
configuration header. The next step when running the `configure`
script is much more time consuming so performance on buildconf
level is a bit questionable and won't be noticed on today's
systems.
Additionally:
- buildconf now removes cache and all targets and uses -f option on
the first step i.e. autoconf. The autoheader does not need the -f
option in this case.

Checked in LiteSpeed SAPI 7.5, addressed two main problems in "clean shutdown" introduced in 7.4.3,
1. falls in an infinite loop because PHP engine's inconsistent state, now override the ITIMER_PROF to 0.1 second, clean shutdown must finish before that.
2. generate too much error log, we completely disable "error_reporting" before calling php_request_shutdown().

Fix failed tests for phar
- when $status is boolean, E_NOTICE appears and tests fail
- opcache is never enabled on these tests anyway.
- Add opcache.revalidate_freq=0 to testing script
Instead of checking this in the tests files it can be used directly in
the main testing script. Also this fixes failed tests.
- Use opcache_invalidate() instead of sleep() delay in some tests. Some
delays are still used since the opcache_invalidate seems to be buggy
and not working as expected.
Move Oniguruma related config stuff to where it belongs
Oniguruma is exclusively used by ext/mbstring, and only if mbregex is
enabled. Therefore it is unnecessary and confusing to have Oniguruma
related config stuff scattered elsewhere.
While we're at it, we also remove the referral to the bundled libonig
which is removed as of PHP 7.4.0, and the duplicated call to
`PHP_INSTALL_HEADERS()`.
The classic Windows console only supports the Unicode BMP, so it can't
handle the LIGHTNING MOOD character (U+1F5F2). It also seems that
common fonts do not support the LIGHTNING (U+2607) character, so a
general removal is appropriate.
However, Windows is already "ready for the future"[1], but PHP for
Windows is not (yet).
ext/win32std is unmaintained for years, so it is highly unlikely that
it is available. We therefore use regedit instead to register the
event source. We also remove the bundled syslog.reg, since it is of no
use, unless generated for the respective installation.

Allow multiple cache instances per user/host on Windows
Formerly, there was at most a single OPcache instance per user and the
so called system ID (which is determined from the PHP version).
Sometimes multiple OPcaches might be desired, though, particularly for
unrelated CLI scripts, which may even be necessary (e.g. for our test
suite in parallel mode).
We therefore introduce a new INI directive `opcache.cache_id` which
allows to configure independent OPcache instances for the same user.
We also use `GetUserNameW()` instead of `php_win32_get_username()`,
because the latter retrieves the user name encoded in the
`default_charset`, which can obviously yield different results for
different charsets, leading to OPcache "incompatibilities". Slightly
worse, some characters may not even be encodeable in the
`default_charset` and would be replaced by question marks, which could
result in different users sharing the same OPcache.
We also refactor, and re-use existing APIs to avoid duplicated code.
Revert "Remove Windows syslog script and syslog.reg"
This reverts commit cc44bad1f6ded6a62c9bbe4d145b5b418aa775f4, since its
assumptions were not correct. Actually, the classic event logging is
still used by PHP, because Windows 7 is still to be supported for a
while. Without the respective registry entries, the event log entries
show an error message regarding missing ID descriptions.
Thanks to ab@php.net for hinting at this!
Obviously, the part depending on ext/win32std has still to be
overhauled, and further improvements are conceivable; we will address
this in due course.
By adding a flag to avoid forced fstat for includes. The two fstats
will happen back to back and we don't care about a possible
invalidation.
I was hoping to move this higher up in the stack and make the
ISREG check somewhere in fsizer of fixup, but this doesn't really
seem to be possible. E.g. an FP stdin handle will not be a regular
file but of course needs to be allowed. Additionally custom stream
wrappers may not implement this functionality.
If we're including a file via PHP streams, we're not going to trust
the reported file size anyway and populate in a loop -- so don't
bother determining the file size in the first place. Only do this
for non-tty HANDLE_FP now, which is the only case where this
information was used.
