This is a comprehensive refactoring of the error mechanism of the Intl extension.
By moving the prefixing of the current method/function being executed to actual error message creation by accessing the execution context, we get the following benefits:
- Accurate error messages indicating *what* call caused the error
- As we *always* "copy" the message, the `copyMsg` arg becomes unused, meaning we can reduce the size of the `intl_error` struct by 4 bytes.
- Saving it as a zend_string means we know the length of the message
- Remove the need to pass around a "function name" `char*` across multiple calls
- Use Intl's exception mechanism to generate exceptions for constructor call
- This removes the need for replacing the error handler
- Which didn't do anything anyway in silent mode, which required throwing non-descriptive exceptions
This requirements bump should rarely affect anybody in practice. All
major distros already ship more recent ICU versions, and even for
Solaris 11, ICU 57.1 is available via OpenCSW. Note that ICU 57.1 has
been released on 2016-03-23[1].

Closes GH-16688.
1. Update: http://www.php.net/license/3_01.txt to https, as there is anyway server header "Location:" to https.
2. Update few license 3.0 to 3.01 as 3.0 states "php 5.1.1, 4.1.1, and earlier".
3. In some license comments is "at through the world-wide-web" while most is without "at", so deleted.

We're starting to see a mix between uses of zend_bool and bool.
Replace all usages with the standard bool type everywhere.
Of course, zend_bool is retained as an alias.
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.
RFC: https://wiki.php.net/rfc/tostring_exceptions
And convert some object to string conversion related recoverable
fatal errors into Error exceptions.
Improve exception safety of internal code performing string
conversions.
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.
