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.

PHP requires boolean typehints to be written "bool" and disallows
"boolean" as an alias. This changes the error messages to match
the actual type name and avoids confusing messages like "must be
of type boolean, boolean given".
This a followup to ce1d69a1f6, which
implements the same change for integer->int.
Introduces a ZEND_PARSE_PARAMS_THROW flag for zpp, which forces to
report FAILURE errors using a TypeException instead of a Warning,
like it would happen in strict mode.
Adds a zend_parse_parameters_throw() convenience function, which
invokes zpp with this flag.
Converts all cases I could identify, where we currently have
throwing zpp usage in constructors and replaces them with this API.
Error handling is still replaced to EH_THROW in some cases to handle
other, domain-specific errors in constructors.
