Description

Refactor the glob pattern code out of FileContext and FileSystem into a package private GlobFilter and the reusable GlobPattern class (InterfaceAudience.Private)

Also fix the handling of ^ outside character class ([...]) reported in HADOOP-6618 and make the glob pattern code less restrictive (not throwing on some valid glob patterns.) and more POSIX standard compliant (support [!...]).
