Remove unused Table::$_idGeneratorType

Fix Index construction

Update CreateSchemaSqlCollector.php setting default namespace/schema nam...

supportsSchemas() was already added (see last commit).
So changed expectation from 1 to any.

Added the supportsSchemas method in the mock because it's being used now.

The current implementation uses the schema name as namespace name.
Some platforms don't support schema's, but a namespace name still needs to
be present. Added namespace name 'default' when there is no default schema
name.

SQL Server Paginator bug fix

Apperently the doModifyLimitQuery function does not only cover SQL
generated by ORM (Makes sense to use DBAL as seperate component). Therefor
it can happen that a column name does not include the table and so the old
logic was valid anyway. (line 867-869)

Fixed the unit tests to use real column names instead of aliases.

1. combine the regexes into one. The only thing that needs to be captured
is the alias. Used a non-capturing group for "AS " to avoid confusion and
have cleaner regex. It tries to match "Table.Column Alias" or
"Table.Column AS Alias". (line 861)
2. No fallback on line 865 like "$column['table'] . '.' .
$column['column']" this wouldn't make sense as this can not be possible
when it's a wrapped query. Better not insert some random SQL that's gonna
confuse the hell out of everybody.
3. Removed "($column['hasTable'] ? $column['table']  . '.' : '') .
$column['column']" because the original regex always tries to match the
table name. Therefor hasTable will always be true or the entire function
fails anyway. (this references line 868 now) (this was unit tested on
mysql, postgresql and sql server and did not increase errors/failures)

default schema name is public for postgresql not default. Added debug
statements to test travis-CI.

Update SQLServerPlatform.php by adding methods related to schema.

and takes inspiration from this PR https://github.com/doctrine/dbal/pull/374 which was written for this bug http://www.doctrine-project.org/jira/browse/DDC-2622

Fixed a small mistake where method getDefaultSchemaName was declared as protected instead of public.

Put the responsibility to give the default schema name from CreateSchemaSqlCollector to the Platforms (abstract, sqlserver, postgresql)

Fixed logic error in Sharding component

The namespace is used as name for the database schema. For SQL Server the default schema name is "dbo" and not "default".

The platform indicates support for schema's here: https://github.com/doctrine/dbal/blob/master/lib/Doctrine/DBAL/Platforms/SQLServerPlatform.php#L129

But is missing relevant methods:
schemaNeedsCreation() --> to detect if schema creation is needed
and
getCreateSchemaSQL() --> to create a schema

HHVM compatibility: func_get_args

All func_get_args() calls have been moved to the top of the methods
because HHVM doesn't keep a copy of the original args for performance
reasons.

See facebook/hiphop-php#1027 for details.

Checkstyle (Fix additional space in "if" statement)

- Switch from phing to ant
- Add composer archive for packages
- Remove PEAR package building

What is colnum?

Don't add 'NOT NULL' to the 'ALTER TABLE' when that hasn't changed
