Use ASCII case conversion instead of locale-dependent case conversion in
the following places:
* grapheme_stripos() and grapheme_strripos() in the "fast" path
* ldap_get_entries()
* oci_pconnect() for case folding of parameters when constructing a key
into the connection or session pool
* SoapClient: case folding of function names
* get_meta_tags(): case conversion of property names
* http stream wrapper: header names
* phpinfo(): anchor names
* php_verror(): docref URLs
* rfc1867.c: Content-Type boundary parameter name
* streams.c: stream protocol names
Using locale-dependent case folding for these cases is either
unnecessary or actively incorrect. These functions could have
misbehaved when used with certain locales (e.g. Turkish).

We need to avoid storing it in the first place, as we don't
really have a good place to release it later. If headers haven't
been sent yet, send_headers will do this. sapi_deactive happens
too late in the shutdown sequence and will result in leak reports.
The stream position is not related to the buffer, and needs to be
updated for non-seekable streams as well. The erroneous condition
around the position update is a relict of an old commit[1].
The unexpected test expectation is due to bug #81345.

When flushing the stream filters actually causes data to be written to
the stream, we need to update its position, because that is not done by
the streams' write methods.
Closes GH-7354.
This used to be necessary in the past because the NUM_BUF_SIZE
was set to 512, which is shorter than DOUBLE_MAX_LENGTH. Now the
value is either DOUBLE_MAX_LENGTH or larger (2048).
Suppress checking during the actual parsing, but make sure to
duplicate strings on activate. The parsing result may be shared
across requests, but activation should work on per-request strings.
tsrm_realpath() internally always allocates a string. If the out
parameter is provided it gets copied there and freed. What we
were doing here was to first copy the path from the allocated
string to a stack buffer, and then copy it from the stack buffer
to a zend_string. We might as well save one copy and one buffer.
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.

When mapping the file, we need to pass the proper `dwFileOffsetHigh`
instead of `0`.
