Fixed tests after added deprecation notice.

Fixed PHP-818: Add deprecation notices to usage of Mongo.

For the tests, I also swapped to using "MongoClient" by default and looked at
individual tests at what they were testing to decide whether to go with
"old_mongo" specifically or mongo/new_mongo() or equivalents. I guess some
choices could be debated though.

In one case (tests/generic/bug00635.phpt) I changed the expected output (beyond
deprecation notices), but this test was testing something unrelated to w=0/w=1.

Fixed PHP-774: Mark MongoCollection::toIndexString as deprecated.

For this to work, I also had to separate it out as otherwise our own
ensureIndex() would throw a deprecation warning.
Fixed NULL-dereference error and ZTS build.
Fixed tests for PHP 5.2.
Fixed another NULL-dereference

And adding missing tests for deleteIndex/deleteIndexes so that we can see that
this failed. However, I noticed a really annoying behaviour for deleteIndex(
string ). Instead of it dropping an index with the name "string", it uses it as
a field name to append "_1" too. So you can not use it at all for user-named
indexes. I've added issue PHP-817 to the 2.x milestone to sort that out.

Throw deprecation notices for properties mark as ZEND_ACC_DEPRECATED

PHP doesn't support deprecating properties so we have to overload the
default property handler and lookup the property flags to issue the
warning
PHP-797: Deprecate the properties on MongoClient

They aren't actually used or updated (except for the ->connected, which
is a pain and better alternatives exist already).
PHP-797: Deprecate the exception properties, the getXX() methods should be used
instead
Add a testcase for MongoClient properties, making sure we only deprecate
the property names when they are accessed from valid scopes and don't
act like a dbname
Fix test after deprecating the connected property
Fix zts build and make Travis happy =)
