It is possible to pass flags when opening an SQLite database. For
Sqlite < 3.5.0 these are ignored, since `sqlite3_open` doesn't support
flags. Neither a warning or notice is raised in this case, nor is this
behavior documented in the PHP manual. Instead of fixing it either
way, we lift the requirement to SQLite 3.5.0 (released on 2007-09-04)
instead of the former SQLite 3.3.9 (released on 2007-01-04).
Some INI processors allow to specify empty values by just giving the
key without the equals sign, for instance MySQL and Python. It appears
to be sensible to add this possibility to our INI parser, so that it
can be used for such INI files as well. We choose NULL as the value of
empty values.
This syntactical enhancement is a (minor) BC break, though, as can be
seen by the necessary change to bug49692.ini. The “comment” formerly
has been simply ignored, but now it would be parsed as key with an
empty value.
This PR is based on Adam's former patch.
According to the “Deprecate and remove INTL_IDNA_VARIANT_2003” RFC[1],
we change the default of the $variant parameter of `idn_to_ascii()` and
`idn_to_utf8()` from `INTL_IDNA_VARIANT_2003` to
`INTL_IDNA_VARIANT_UTS46`.

Given that ICU is a set of lively developed libraries, that ICU 50.1
has been released on 2012-11-05, and PHP 7.4 is scheduled to be
released seven years after it, we consider it appropriate to ditch
these legacy versions.
Particularly, that would be a reasonable groundwork to implement part
two of the “Deprecate and remove INTL_IDNA_VARIANT_2003” RFC[1], namely
to default idn_to_ascii()'s and idn_to_utf8()'s $variant parameter to
INTL_IDNA_VARIANT_UTS46, which is not defined in ICU < 4.6.

We work around a strlen() optimization bug in GCC 8[1] by checking
whether the used GCC exhibits the broken behavior, and if so by
disabling `optimize-strlen`.

Whenever we return with `PSFS_PASS_ON`, we need to update
`bytes_consumed` to not mislead the caller. Instead of fixing the
respective `if` clauses, we eschew the early bail-outs to simplify the
code a bit.
