We also re-allocate twice the size needed in the first place, and not
roughly tripple the size.

Fix #74264: grapheme_strrpos() broken for negative offsets

We must not assume that `usearch_last()` gives the proper result for
negative offsets. Instead we'd need to continue to search backwards
(`usearch_previous`) until we find a proper match. However, apparently
searching backwards is broken, so we work around by searching forward
from the start of the string until we pass the `offset_pos`, and then
use the previous result.

Fix bug #80072: Root live tmpvars after GC

TMPVAR operands are destroyed using zval_ptr_dtor_nogc(), because
they usually cannot contain cycles. However, there are some rare
exceptions where this is possible, e.g. unserialize() return value.
In such cases we rely on the producing code to root the value. If
a GC run occurs between the rooting and consumption of the value,
we would end up leaking it. To avoid this, root all live TMPVAR
values after a GC run.

Closes GH-7210.

The analysis in the bug report wasn't correct (at least not in

the issue was that write_property returned the original variable_ptr

Fix #73630: Built-in Weberver - overwrite $_SERVER['request_uri']

The built-in Webserver's `on_path`, `on_query_string` and `on_url`
callbacks may be called multiple times from the parser; we must not
simply replace the old values, but need to concatenate the new values
instead.

This appears to be tricky for `on_path` due to the path normalization,
so we fail if the function is called again.

The built-in Webserver logs errors during request parsing to stderr,
but this is ignored by the php_cli_server framework, and apparently the
Webserver does not send a resonse at all in such cases (instead of an
4xx). Thus we can only check that a request with an overly long path
fails.

Closes GH-7207.

Fix bug #80728: Don't reset the timeout on ini deactivate

When the time limit for a script is changed, when the script ends,
its INI value will be reset. This calls the event handler for the
timeout change, which will unset then reset the timeout. However,
this is done even if the script is done executing, and say, the CGI
or CLI web server process is idle.

This is probably incorrect, but isn't a problem on most platforms,
because PHP uses a timer that only ticks when the process is active
(that is, executing code). Since when it's idle, it's blocking on
listen/read, it won't tick because nothing executes. However, on
platforms where only the real-time timer is supported, (Cygwin/PASE)
it ticks regardless of if PHP is even executing. This means that the
idle processes are subject to timeouts from the INI reset on script
end.

This makes it so the timer is never set if the state is deactivating.
Testing with the CLI web server indicates the timer no longer
spuriously activates under PASE.

Fix #68471: IntlDateFormatter fails for "GMT+00:00" timezone

GMT+00:00 is recognized by ICU, and is normalized to GMT. There are no
issues when GMT+00:00 is passed to `IntlTimeZone::createTimeZone()`,
but passing it to IntlDateFormatter::__construct() causes a failure,
since there is an additional check regarding the validity. While
checking the validity of the result of `TimeZone::createTimeZone()`[1]
is a good idea, comparing the IDs is overly restrictive. Instead we
just check that the timezone is supported by ICU.
