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.

Allow hacking/env-setup module path to use config file library path

hacking/env-setup now adds the configured library path in ANSIBLE_CONFIG
to the ANSIBLE_LIBRARY environment variable in addition to the previous
default of ANSIBLE_HOME/library.

Fix Linode inventory plugin causing a Chube exception when attempting to obtain information on a specific Linode host

While we're on it, change $pkgdesc to follow its counterpart from
official repositories. Additionally don't install RELEASES.txt and
CONTRIBUTING.md; there is little use for them from the user's perspective.

The Internet is being referred to, but the documentation uses the word 'intranet'.

Refining the fix made in #5885.

Merging this quickly after PR as further testing of of earlier fix demonstrated flaws. Those flaws are now removed and tested to be removed.

It turns out that some of the assumptions in #5885 were slightly off. The previous fix relied on a call to the module to creat a tmp_path. This is insufficent as there are few cases that we need to have the tmp directory before we make the module call. If we don't have a tmp_path before we do a recursive call or when we find a file that does not match the remote md5 hash we need to create a tmp directory. Also we are not more percise when we will need to clean up the remote tmp_path.
