CIVI-SA-2016-11: Potential backtrace leak

An automated security audit (based on static code analysis of the CiviCRM codebase) indicated that a dependency (PEAR CLI from the "packages" folder) could potentially reveal semi-sensitive backtrace data if an attacker could run it and provoke an error.

An exploit of this has not been identified.

As a precautionary measure, CiviCRM v4.7.11 removes PEAR CLI.
