Fix usage of reentrant functions in ext/posix (#13921)

- It's not necessarily an error of sysconf(_SC_GETPW_R_SIZE_MAX) returns -1, as
specified by posix (and the musl implementation always returns -1). Pick an
initial buffer size in this case.
- Reentrant variants return an error number an may not set errno
- Implement retry logic for ttyname_r()
- Fix retry logic for getpwnam_r() (pw would be NULL after the first try)
- Test retry logic by setting the initial buffer size to 1 in debug builds

Refactor utsname.domainname struct member Autoconf check (#13336)

* Refactor utsname.domainname struct member Autoconf check

Autoconf's AC_CHECK_MEMBERS macro (available since Autoconf 2.50) can be
used instead of the compile check. This was originally implemented for
IRIX compatibility, when Autoconf 2.13 didn't have the struct members
checking macro yet.

Macro by default here defines the HAVE_STRUCT_UTSNAME_DOMAINNAME symbol.

* Remove also redundant DARWIN symbol check

Checking in the configuration step also correctly detects missing struct
member on Darwin systems (macos...).

Refactor checks for fpathconf and pathconf

These two might not be available everywhere so we check them in
config.m4 when doing the configure step. Check is skipped for musl libc
due to limited implementation.

Constants that are defined into main/php_config.h:
HAVE_FPATHCONF
HAVE_PATHCONF

Implemented via GH-10238
Related to GH-10350

Fix use-of-uninitialized-value when calling php_posix_stream_get_fd (#11694)

Passing a double pointer to php_stream_cast means the caller of
php_posix_stream_get_fd will never receive the actual value. Moreover,
php_posix_stream_get_fd may only write the low sizeof(php_socket_t) bytes of fd,
so we need to initialize the upper bytes to 0 to avoid partial
use-of-uninitialized-value.

ext/posix: posix_isatty() fix use-of-uninitialized-value (#11676)

When the value passed is not representable as an int then it is not a TTY and thus should return false immediately.
