  -----------
  Add pattern parser for layout patterns

This code is based on the parser from the ch.qos.logback.core.pattern.parser package (from original logback-core). Hence the similarly named package. The code is nearly identical except this version introduces a token position field to track the starting point of each token. This is useful for distinguishing regex characters inside literals from those inside keywords or option lists.

The decoder works by converting the log layout pattern into a regular expression (specifically, only the keywords and their modifiers are converted to regex) and then matching each line in a file against that regular expression. Since literals in the layout pattern can contain regex characters, we must escape them so that they're matched literally or else they could trip up the regex matcher.

For example, this layout pattern:

 "[%level] - %replace(%msg){'foo','[bar]'}%n"

contains regex chars '[' and ']' around "%level". The brackets must be escaped or else they're interpreted as a regex character class. The %replace keyword has a few regex chars, but the keyword and all its modifiers are entirely converted into a regex pattern.

A regex conversion of the above layout pattern might look like this:

 "\[(WARN|DEBUG|TRACE|ERROR|ALL)\] - (.*)\n"

  Log Message:
  -----------
  Change FieldCapturer interface to take a PatternInfo object

The PatternInfo object contains auxiliary details that can be used to parse the field from a given string, including format modifiers, option lists, and children (for composite keywords).

  Remove obsolete files

LayoutPatternInfo.java and LayoutPatternParser.java were moved to ch.qos.logback.core.pattern.parser2 and were renamed to remove the "Layout" prefix. I know I should've used `git mv`, but it wasn't worth the trouble to fix this particular mistake since there weren't many changes to these files. Sue me!
