Now that we have class aliases (DOMNode -> DOM\Node), it has become important to add them to the class map so that it will be possible to generate class synopses for them.
This has been the case at least since PHP 5.4. Thanks to Girgias for
pointing it out.
It appears that there are several global variables internal to mbstring
which can be queried via mb_get_info() and which could be NULL, but
at the very least, we know that "mbstring.http_input" is one of them.

## About Firebird transaction
Firebird is a full transactional database, so the DB itself does not support autocommit mode. (Strictly, there is an autocommit mode, but it is a different concept from the "autocommit" that we are used to with MySQL and others.)
Therefore, a transaction must have started before any operation is performed, and autocommit mode had to be emulated in PHP.
I made sure that a transaction always exists when in autocommit mode. Since the `in_transacntion` function does not work as expected, I have introduced `H->in_manually_txn` to determine whether a transaction is being manually manipulated.
## There are two types of commit/rollback
(I'm not talking about two-phase commit. This change does not take into account two-phase commit.)
There are `isc_commit_retaining` which starts a transaction again in the same context immediately after committing, and `isc_commit_transaction` which closes the transaction as is.
Similarly, there are two types of rollback.
-----------
Due to the default value of the transaction isolation level, autocommit mode may obtain unintended results.
Regarding this, it would be too large to include support for transaction isolation levels in this PR, so I will leave it as is for now.
* fix segfault in `ZEND_BIND_STATIC`
In case a `ZEND_BIND_STATIC` is being executed, while the current chunk is full,
the `zend_array_dup()` call will trigger a OOM in ZendMM which will crash, as
the opline might be a dangling pointer.
* add missing test
* `assert()`ing seems easier than trying to make the compiler to not optimize
* moved from function call to INI setting, so we can use this in other places as well
* make `assert()` work no NDEBUG builds
* document magic number
* fix segfault in `ZEND_FUNC_GET_ARGS`
In case a `ZEND_FUNC_GET_ARGS` is being executed, while the current chunk is
full, the `zend_new_array()` call will trigger a OOM in ZendMM which will crash,
as the opline might be a dangling pointer.
