A connection string may contain just a single key, but
PHP used ";" as the heuristic to detect if a string was a connection
string versus plain DSN. However, a single-key connection string
would get treated like a DSN name, i.e. "DSN=*LOCAL". This makes it
so that "=" is used, as a connection string must contain a key.

According to the relevant Japan Industrial Standards Committee standards,
SJIS 0x5C is a Yen sign, and 0x7E is an overline.
However, this conflicts with the implementation of SJIS in various legacy
software (notably Microsoft products), where SJIS 0x5C and 0x7E are taken
as equivalent to the same ASCII bytes.
Prior to PHP 8.1, mbstring's implementation of SJIS handled these bytes
compatibly with Microsoft products. This was changed in PHP 8.1.0, in an
attempt to comply with the JISC specifications. However, after discussion
with various concerned Japanese developers, it seems that the historical
behavior was more useful in the majority of applications which process
SJIS-encoded text.
Since we are now treating SJIS 0x5C as equivalent to U+005C and 0x7E as
equivalent to U+007E, it does not make sense to convert U+203E (OVERLINE)
to 0x7E, nor does it make sense to convert U+00A5 (YEN SIGN) to 0x5C. Restore
the mappings for those codepoints from before PHP 8.1.0.
It introduces a single function to check file paths passed to OpenSSL
functions. It expands the path, check null bytes and finally does
an open basedir check.
This test was written to always use the sqlite PDO driver; however,
that driver may no longer be available[1], and actually the test is
supposed to work for all drivers – otherwise it should be placed in
ext/pdo_sqlite/tests.

Closes GH-8732.
We must not free parameters which we haven't initialized yet.
We also fix the not directly related issue, that we checked for the
wrong value being `NULL`, potentially causing a segfault.
