Make vm_interrupt and timed_out atomic (#8327)

This is done by adding a new zend_atomic_bool type. The type
definition is only available for compiler alignment and size info; it
should be treated as opaque and only the zend_atomic_bool_* family of
functions should be used.

Note that directly using atomic_bool is complicated. All C++ compilers
stdlibs that I checked typedef atomic_bool to std::atomic<bool>, which
can't be used in an extern "C" section, and there's at least one usage
of this in core, and probably more outside of it.

So, instead use platform specific functions, preferring compiler
intrinsics.

Quote when adding to connection string in (PDO_)ODBC

Because the UID= and PWD= values are appended to the SQLDriverConnect
case when credentials are passed, we have to append them to the string
in case users are relying on this behaviour. However, they must be
quoted, or the arguments will be invalid (or possibly more injected).
This means users had to quote arguments or append credentials to the raw
connection string themselves.

It seems that ODBC quoting rules are consistent enough (and that
Microsoft trusts them enough to encode into the .NET BCL) that we can
actually check if the string is already quoted (in case a user is
already quoting because of this not being fixed), and if not, apply the
appropriate ODBC quoting rules.

This is because the code exists in main/, and are shared between
both ODBC extensions, so it doesn't make sense for it to only exist
in one or the other. There may be a better spot for it.

Closes GH-8307.

main/streams/streams: use copy_file_range() on Linux (#8413)

copy_file_range() is a Linux-specific system call which allows
efficient copying between two file descriptors, eliminating the need
to transfer data from the kernel to userspace and back. For
networking file systems like NFS and Ceph, it even eliminates copying
data to the client, and local filesystems like Btrfs and XFS can
create shared extents.

Use memrchr() when available

On x86_64 glibc memrchr() uses SSE/AVX CPU extensions and works much
faster then naive loop. On x86 32-bit we still use inlined version.

memrchr() is a GNU extension. Its prototype becomes available when
<string.h> is included with defined _GNU_SOURCE macro. Previously, we
defined it in "php_config.h", but some sources may include <string.h>
befire it. To avod mess we also pass -D_GNU_SOURCE to C compiler.
