Andrey Loskutov 2f5a08798e Reimplementation of ignore rule parser

The current IgnoreRule/FileNameMatcher implementation scales not well
with huge repositories - it is both slow and memory expensive while
parsing glob expressions (bug 440732). Addtitionally, the "double star"
pattern (/**/) is not understood by the old parser (bug 416348).

The proposed implementation is a complete clean room rewrite of the
gitignore parser, aiming to add missing double star pattern support and
improve the performance and memory consumption.

The glob expressions from .gitignore rules are converted to Java regular
expressions (java.util.regex.Pattern). java.util.regex.Pattern code can
evaluate expression from gitignore rules considerable faster (and with
less memory consumption) as the old FileNameMatcher implementation.
