Fix #66828: iconv_mime_encode Q-encoding longer than it should be

Before the fix for bug 48289 has been applied, the algorithm to
construct a Q-encoded-word has been optimistic, i.e. try to encode as
many bytes that *may* fit in the remaining space, calculate the actual
length of the Q-encoded word, and if it's too long, try again with a
reduced size. However, the fix for the mentioned bug replaced this by
a pessimistic algorithm, which always terminates[1] the for loop[2]
during the first iteration (which renders the following 3 lines as dead
code), and as such easily produces unnecessarily short encoded-words.
Instead the proper fix for the bug would have been to make sure that
`out_size` is always decremented, if the space isn't sufficient for the
encoded-word.

This reverts commit 3f3e914df33793a36f51b4e44745d6a5aec4f685.

The commit broke some tests on Windows, and generally needs more

Implement #67331: Have parse_ini_file add empty entries

Some INI processors allow to specify empty values by just giving the
key without the equals sign, for instance MySQL and Python.

Implement #67331: Have parse_ini_file add empty entries

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.

Require ICU ≥ 50.1

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.
