Always throw TypeException on throwing zpp failures

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.

Patch improvement:

Removed the corresponding core code.
Fixed ext/com_dotnet and ext/date.
Refactored ext/intl changes.
Improved ext/fileinfo and ext/pdo changes.
Fixed tests.

Converted intl extension to use IntlException in constructors.

first shot remove TSRMLS_* things

Add smart_str_append for appending zend_strings

Also replaces usages in Zend/ and ext/standard

Move smart_str implementation into Zend/

So we can use it there as well...

For now I've retained the zend_smart_str_public.h header, though
it would probably be better to just m

it would probably be better to just move that one struct into
zend_types.h.

BreakIterator and RuleBasedBreakiterator added

This commit adds wrappers for the classes BreakIterator and
RuleBasedbreakIterator. The C++ ICU classes are described here:
<http://icu-project.org/apiref/icu4c/classBreakIterator.html>
<http://icu-project.org/apiref/icu4c/classRuleBasedBreakIterator.html>

Additionally, a tutorial is available at:
<http://userguide.icu-project.org/boundaryanalysis>

This implementation wraps UTF-8 text in a UText. The text is
iterated without any copying or conversion to UTF-16. There is
also no validation that the input is actually UTF-8; where there
are malformed sequences, the UText will simply U+FFFD.

The class BreakIterator cannot be instantiated directly (has a
private constructor). It provides the interface exposed by the ICU
abstract class with the same name. The PHP class is not abstract
because we may use it to wrap native subclasses of BreakIterator
that we don't know how to wrap. This class includes methods to
move the iterator position to the beginning (first()), to the
end (last()), forward (next()), backwards (previous()), to the
boundary preceding a certain position (preceding()) and following
a certain position (following()) and to obtain the current position
(current()). next() can also be used to advance or recede an
arbitrary number of positions.

BreakIterator also exposes other native methods:
getAvailableLocales(), getLocale() and factory methods to build
several predefined types of BreakIterators: createWordInstance()
for word boundaries, createCharacterInstance() for locale
dependent notions of "characters", createSentenceInstance() for
sentences, createLineInstance() and createTitleInstance() -- for
title casing breaks. These factories currently return
RuleBasedbreakIterators where the names of the rule sets are found
in the ICU data, observing the passed locale (although the locale
is taken into considering there are very few exceptions to the
root rules).

The clone and compare_object PHP object handlers are also
implemented, though the comparison does not yield meaningful results
when used with >, <, >= and <=.

Note that BreakIterator is an iterator only in the sense of the
first 'Iterator' in 'IteratorIterator', i.e., it does not
implement the Iterator interface. The reason is that there is
no sensible implementation for Iterator::key(). Using it for
an ordinal of the current boundary is not feasible because
we are allowed to move to any boundary at any time. It we were
to determine the current ordinal when last() is called we'd
have to traverse the whole input text to find out how many
breaks there were before. Therefore, BreakIterator implements
only Traversable. It can be wrapped in an IteratorIterator,
but the usual warnings apply.

Finally, I added a convenience method to BreakIterator:
getPartsIterator(). This provides an IntlIterator, backed
by the BreakIterator PHP object (i.e. moving the pointer or
changing the text in BreakIterator affects the iterator
and also moving the iterator affects the backing BreakIterator),
which allows traversing the text between each boundary.
This iterator uses the original text to retrieve the text
between two positions, not the code points returned by the
wrapping UText. Therefore, if the text includes invalid code
unit sequences, these invalid sequences will be in the output
of this iterator, not U+FFFD code points.

The class RuleBasedIterator exposes a constructor that allows
building an iterator from arbitrary compiled or non-compiled
rules. The form of these rules in described in the tutorial linked
above. The rest of the methods allow retrieving the rules --
getRules() and getCompiledRules() --, a hash code of the rule set
(hashCode()) and the rules statuses (getRuleStatus() and
getRuleStatusVec()).

Because the RuleBasedBreakIterator constructor may return parse
errors, I reuse the UParseError to text function that was in the
transliterator files. Therefore, I move that function to
intl_error.c.

common_enum.cpp was also changed, mainly to expose previously
static functions. This avoided code duplication when implementing
the BreakIterator iterator and the IntlIterator returned by
BreakIterator::getPartsIterator().
