Fix #77291: magic methods inherited from a trait may be ignored
When adding methods from a trait, we must not assume that a method name
with the same length as the name of the using class is either a PHP 4
style constructor, or not a magic method at all – it may well be
another magic method.
We mostly preserve the spirit of the optimization which caused this
regression, and avoid string comparisons for all method names which can
never be magic methods.
Albeit CSV is still a widespread data exchange format, it has never been
officially standardized. There exists, however, the “informational” RFC
4180[1] which has no notion of escape characters, but rather defines
`escaped` as strings enclosed in double-quotes where contained
double-quotes have to be doubled. While this concept is supported by
PHP's implementation (`$enclosure`), the `$escape` sometimes interferes,
so that `fgetcsv()` is unable to correctly parse externally generated
CSV, and `fputcsv()` is sometimes generating non-compliant CSV. Since
PHP's `$escape` concept is availble for many years, we cannot drop it
for BC reasons (even though many consider it as bug). Instead we allow
to pass an empty string as `$escape` parameter to the respective
functions, which results in ignoring/omitting any escaping, and as such
is more inline with RFC 4180. It is noteworthy that this is almost no
userland BC break, since formerly most functions did not accept an empty
string, and failed in this case. The only exception was `str_getcsv()`
which did accept an empty string, and used a backslash as escape
character then (which appears to be unintended behavior, anyway).
The changed functions are `fputcsv()`, `fgetcsv()` and `str_getcsv()`,
and also the `::setCsvControl()`, `::getCsvControl()`, `::fputcsv()`,
and `::fgetcsv()` methods of `SplFileObject`.
The implementation also changes the type of the escape parameter of the
PHP_APIs `php_fgetcsv()` and `php_fputcsv()` from `char` to `int`, where
`PHP_CSV_NO_ESCAPE` means to ignore/omit escaping. The parameter
accepts the same values as `isalpha()` and friends, i.e. “the value of
which shall be representable as an `unsigned char` or shall equal the
value of the macro `EOF`. If the argument has any other value, the
behavior is undefined.” This is a subtle BC break, since the character
`chr(128)` has the value `-1` if `char` is signed, and so likely would
be confused with `EOF` when converted to `int`. We consider this BC
break to be acceptable, since it's rather unlikely that anybody uses
`chr(128)` as escape character, and it easily can be fixed by casting
all `escape` arguments to `unsigned char`.
This patch implements the feature requests 38301[2] and 51496[3].
The `$mode` parameter of `imagecropauto()` defaults to `-1`. However,
`-1` is changed to `GD_CROP_DEFAULT` right away, so basically the
default is `GD_CROP_DEFAULT`, which is rather confusing and
unnecessary.
Therefore, we change the default to `IMG_CROP_DEFAULT`, but still allow
an explicit `-1` to be passed for BC reasons, in which case we trigger
a deprecation notice, so we can rid the `-1` support eventually.

Split php_array_merge_or_replace_wrapper() into php_array_merge_wrapper() and php_array_replace_wrapper().
Avoid array duplication when merging with an empty array.

Fixed bug #77275
Instead of juggling with this problem during literal compaction,
make sure that we always initialize Z_EXTRA for literals, which
seems like the more robust solution.

Set AC_CONFIG_AUX_DIR to build directory
The Autoconf macro AC_CONFIG_AUX_DIR can set the location of the
auxiliary build tools such as config.guess, config.sub, and bundled
libtool scripts and moves these bundled files from the root directory
to the build subdirectory.
Additionally some changes in this context or as a part of obsoletion:
- The LT_TARGETS variable in build/build2.mk file was once used as a part
of the Automake step. It's not used anymore and has been refactored to
separate makedist script directly.
- ltconfig is not used anymore since libtool 1.4+ cf8d1563c27a70fdd24055c1e80218ec7b5962d6
- phpize file locations for the config.guess, config.sub, and ltmain.sh
has been refactored accordingly.

ext/curl: port to pkg-config macro and consistently require its use
curl 7.15.1 in December 2006 first added pkg-config support, which is
earlier than the minimum supported version for php. This should
therefore be uiversally supported.
