Formalize return type to zend_result for PGSQL_API functions

ValueError if lengths is less than 0

Use ZEND_ASSERT() instead of plain assert()

Use ZEND_NUM_ARGS() explicitly

Boolify _php_pgsql_link_has_results()

Boolify _php_pgsql_detect_identifier_escape() and rename it

New name is _php_pgsql_identifier_is_escaped()

Add zend_ulong_to_str() API

No point in going through a smart_str and append_unsigned if we
can construct the result directly...

Use zend_string_equals_(literal_)ci() API more often

Also drive-by usage of zend_ini_parse_bool()

Closes GH-6844

Introduce pseudo-keyword ZEND_FALLTHROUGH

And use it instead of comments

Use zend_string_equals() API instead of strcmp() in PGSQL extension

And tiny drive by refactor at the same time for more usages

Make convert_to_*_ex simple aliases of convert_to_*

Make convert_to_*_ex simple aliases of convert_to_*

Historically, the _ex variants separated the zval first, if a
conversion was necessary. This distinction no longer makes sense
since PHP 7.

The only difference that was still left is that _ex checked whether
the type is the same first, but the usage of these macros did not
actually distinguish on whether such an inlined check is valuable
or not in a given context.

Also drop the unused convert_to_explicit_type macros.

Don't accept null in pg_unescape_bytea()

This is an error that slipped in via 8d37c37bcdbf6fa99cd275413342457eeb2c664e.
pg_unescape_bytea() did not accept null in PHP 7.4, and it is not
meaningful for it to accept null now -- it will always fail, and now
with a misleading OOM message.

Additionally, do not display the argument name for these errors.

Remove redundant check

pg_unescape_bytea() can only fail on OOM

The implementation did not check for PQunescapeBytea failure
correctly, because it checked for a null pointer after estrndup,
which certainly cannot happen. Inspection of the PGunescapeBytea
implementation has shown that this function can only fail on OOM,
so let's check for that explicitly and remove false as a possible
return type.

While we're here, avoid an unnecessary copy of the result.
