While the encrypted parameter's documentation clearly states that it needs to
be set, if you are focused on the password parameter's documentation, there's
nothing to draw your attention to the fact that encrypted may also need to be
set.

The previous sync_binary_log is not a real MySQL variable.

The mysqldb Ansible module will fail if the state specified is import or dump with a '1045: Access Denied' mysql error for complex passwords.

This is caused by the extra quote around the '--password' argument to mysqldump, as pipes.quotes already quotes the password string.

>>> "--password='%s'" % pipes.quote('simple')
"--password='simple'"

>>> "--password='%s'" % pipes.quote('c0mplexp@ssword!')
"--password=''c0mplexp@ssword!''"

>>> "--password='%s'" % pipes.quote('password with space')
"--password=''password with space''"

timeit shows a speedup of ~3x on Python 2.7.5 x86_64.
It also makes the code a bit shorter.

Tests clean.

Fixes odd encoding problem with wait_for_service.

* Adds another module utility file which generalizes the
  access of urls via the urllib* libraries.
* Adds a new spec generator for common arguments.
* Makes the user-agent string configurable.

This is not supported in Python 2.6. Just use positional arguments.

From the documentation it is not immediately clear that the 'target'
option refers to a location on the remote host. This change emphasizes that.
In addition to .sql files, .bz2 and .gz files are supported for dumps and
restores. This is now documented.

The SET GLOBAL statement requires properly quoting of values. For example, the
following correct queries will fail if quotes are toggled:

mysql> SET GLOBAL innodb_lru_scan_depth = 2000;
mysql> SET GLOBAL master_info_repository = "TABLE";

`mysql_variable` module doesn't quote the value argument, therefore
string values will fail.

  # this task will pass, 2000 is passed without quotes
  - name: set a numeric value
    mysql_variable: variable=innodb_lru_scan_depth value=2000

  # this task will fail, TABLE is passed without quotes
  - name: set a string value
    mysql_variable: variable=master_info_repository value=TABLE

With this patch prepared statements are used. Proper quoting will be
done automatically based on the type of the variables thus an attempt
to convert to int, then to float is done in first place.

Booleans values, ie: ON, OFF, are not specially handled because they
can be quoted. For example, the following queries are correct and
equivalent, they all set _innodb_file_per_table_ to logical _True_:

mysql> SET GLOBAL innodb_file_per_table = "ON";
mysql> SET GLOBAL innodb_file_per_table = ON;
mysql> SET GLOBAL innodb_file_per_table = 1;

Tested in mysql 5.5 and 5.6.

Previously postgresql_user quoted user supplied identifers to create
grant statements that look like this:

    GRANT SELECT on "tablename" to "user";

Which only works if the tablename is not in a namespace.  If you supply
a namespaced tabelname like "report.revenue" then it creates this
incorrect statement:

    GRANT SELECT on "report.revenue" to "user";

Which will not find the "revenue" table in the "report" namespace, but
will rather look for a table named "report.revenue" in the current
(default public) namespace.  The correct form is:

    GRANT SELECT on "report"."revenue" to "user";

This approach could have the unfortunate effect that code that
previously relied on the other behavior to grant privileges on tables
with periods in their names may now break.  PostgreSQL users
typically shouldn't name tables as such, and users can still access the
old behavior and use tablenames with periods in the if they must by
supplying their own quoting.

The password is passed on a command line for dump and import and needs
quoting.

Ideally, this would not be passed on a command line at all - any ideas?
Or at least have a stronger form of quoting so that embedded single
quotes will be escaped.

The code for mysql_db did not pass the port argument when state=dump or
state=import.

Make the changed status for postgres_db under CHECKMODE match the
status that would be returned normally.

Revert "No longer need to reference 'version_added' in docs for these, as this was quite a while ago."

This reverts commit ff0a41d4.
