Fix bug #73182: PHP SOAPClient does not support stream context HTTP headers in array form

This code is modelled after how `http_fopen_wrapper.c` does things,
which apparently is just looping over the array and handling each string
the same way as if we passed a header string directly.

Also fixes a potential crash in `php_sdl.c` but without adding support
for header arrays there (yet) because the code is untested.

Closes GH-15817.

Fix GH-12838: [SOAP] Temporary WSDL cache files not being deleted

If there are two users that can execute the script that caches a WSDL,
but the script is owned by a single user, then the caching code will
name the cached file with the file owner username and a hash of the uri.
When one of the two tries to rename the file created by the other
process, this does not work because it has no permission to do so.
This then leaves temporary files floating in the temp directory.

To fix the immediate problem, unlink the file after rename has failed.
On the long term, this has to be fixed by taking the username of the
process instead of the username of the file owner.

Closes GH-12841.

Fix bug #75306: Memleak in SoapClient

Fix bug #66150: SOAP WSDL cache race condition causes Segmentation Fault

When we have two processes both trying to cache a WSDL, they might start
writing the data to the same temporary file, causing file corruption due
to the race condition. Fix this by creating a temporary file first, and
then moving it to the final location. If moving fails then we know
another process finished caching first.

This also fixes #67617 as a consequence of its implementation.

Closes GH-12469.

Reduce memory allocated by var_export, json_encode, serialize, and other (#8902)

smart_str uses an over-allocated string to optimize for append operations. Functions that use smart_str tend to return the over-allocated string directly. This results in unnecessary memory usage, especially for small strings.

The overhead can be up to 231 bytes for strings smaller than that, and 4095 for other strings. This can be avoided for strings smaller than `4096 - zend_string header size - 1` by reallocating the string.

This change introduces `smart_str_trim_to_size()`, and calls it in `smart_str_extract()`. Functions that use `smart_str` are updated to use `smart_str_extract()`.

Fixes GH-8896

Fix GH-8538: SoapClient may strip parts of nmtokens

When stripping the namespace prefix, we can assume that this does not
contain any colons, while the rest of the name may contain colons.
Hence we must not use `strrchr()` but rather `strchr()` instead.

Use more compact representation for packed arrays.

- for packed arrays we store just an array of zvals without keys.
- the elements of packed array are accessible throuf as ht->arPacked[i]
instead of ht->arData[i]
- in addition to general ZEND_HASH_FOREACH_* macros, we introduced similar
familied for packed (ZEND_HASH_PACKED_FORECH_*) and real hashes
(ZEND_HASH_MAP_FOREACH_*)
- introduced an additional family of macros to access elements of array
(packed or real hashes) ZEND_ARRAY_ELEMET_SIZE, ZEND_ARRAY_ELEMET_EX,
ZEND_ARRAY_ELEMET, ZEND_ARRAY_NEXT_ELEMENT, ZEND_ARRAY_PREV_ELEMENT
- zend_hash_minmax() prototype was changed to compare only values

Because of smaller data set, this patch may show performance improvement
on some apps and benchmarks that use packed arrays. (~1% on PHP-Parser)

TODO:
- sapi/phpdbg needs special support for packed arrays (WATCH_ON_BUCKET).
- zend_hash_sort_ex() may require converting packed arrays to hash.

Use ASCII lower case for misc case folding

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

* 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).
