Fixes #8169

Include unicode and var_precedence tests in 'all' target

The ansible PyPi package, and RPM both require crypto>=2.6.  This change
carries that dependency into the ansible DEB package.  Note, for
ubuntu-12.04, this dependency is only satisfied by a PPA.  Users
installing from 'ppa:ansible/ansible' will not be affected..

Revert "Use atomic move function on known host file in paramiko to prevent rare occurance of Control-C"

"allow_no_value=True" for ini_file module

Adding test Coverage for mysql_variable module

Add support for environment variables in GCE module.

Use mysql_variable to query, set and update variables.
Assert using user and password to query, set and update  variables.
Assert using single quotes, double quotes and no quotes  when using variables

filter_leading_non_json_lines effectively does

re.match(".*\w+=\w+.*", line)

for every line of output. This has abysmal performance in case of large
Base64-encoded data (which ultimately does not match the regex but does
match the .*\w+= part) as returned e.g. by the template module (diffs).

Replacing the match with

re.search("\w=\w", line)

drops the complexity back to linear, and actually usable with large
diffs from the template module (a 150 KB Base64 diff kept Ansible
spinning at 100% cpu for minutes).

Also, check the easy cases (line.startswith) first while we're here.
