Fixes #3336.

The first capturing group of the parser regex was stopping form the moment it would find a `[` character.

The blob type maps BLOB (and also TEXT) columns to PHP streams.
Internally, they use the ParameterType::LARGE_OBJECT (i. e. \PDO::PARAM_LOB)
binding type, which suggests that efficient handling of PHP stream resources
was intended.

However, at least when using the mysqli driver, stream resources passed into
insert() or update() are simply cast to strings. As a result, a literal
string like "Resource id #126" will end up in the database.

This PR fixes the issue by correctly processing streams in the
MysqliStatement when they are passed with the ParameterType::LARGE_OBJECT
binding type. It uses the mysqli::send_long_data() method to pass stream
data in chunks to the MySQL server, thus keeping the memory footprint low.

This method does not (despite claims to the contrary) allow to bypass the
max_allowed_package size!

The pdo_mysql driver was already capable of handling streams this way.
Now this is covered by tests.

Additional notes on MySQL's max_allowed_packet:

This change does not not intend to work around the max_allowed_packet setting,
and quick tests show that this is not possible: When MySQL is configured to use
a low max_allowed_packet value, an error will be triggered stating

  Parameter of prepared statement which is set through
  mysql_send_long_data() is longer than 'max_allowed_packet' bytes.

Documentation for the underlying mysql_stmt_send_long_data() C API function
suggests that max_allowed_packet is always a hard limit.

What mysqli::send_long_data() seems to do is that every data chunk of data
passed to it is immediately sent out to the network. I have confirmed this
using tcpdump, and so the advantage might be that we can keep the memory
footprint low on the PHP side while processing streams.
