Name change from default_checks.xml to curated_checks.xml

Change name to reflect more appropriately what it actually contains.
That is a list of curated checkstyle rules based originally off of the
sun_checks.xml.
Modify AvoidNestedBlocks checkstyle rule

Enable allowInSwitchCase because a case in a switch statement does not
implicitly form a block. Thus to be able to introduce local variables
that have case scope it is necessary to open a nested block.
Enable MutableException checkstyle rule

Ensures that exceptions (defined as any class name conforming to some
regular expression) are immutable (i.e., have only final fields).
Enable OuterTypeFilename checkstyle rule

Checks that the outer type name and the file name match. For example,
the class Foo must be in a file named Foo.java.
Enable CovariantEquals checkstyle rule

Checks that classes that define a covariant equals() method also
override method equals(java.lang.Object).
Enable DeclarationOrder checkstyle rule

According to Code Conventions for the Java Programming Language , the
parts of a class or interface declaration should appear in the following
order:

1. Class (static) variables. First the public class variables, then the
   protected, then package level (no access modifier), and then the
   private.
2. Instance variables. First the public class variables, then the
   protected, then package level (no access modifier), and then the
   private.
3. Constructors
4. Methods
Enable DefaultComesLast checkstyle rule

Check that the default is after all the [case]s in a switch statement.
Enable FallThrough checkstyle rule

Checks for fall through in switch statements Finds locations where a
case contains Java code - but lacks a break, return, throw or continue
statement.
Enable IllegalType checkstyle rule

Checks that particular class are never used as types in variable
declarations, return values or parameters. Includes a pattern check
that by default disallows abstract classes.
Enable StringLiteralEquality checkstyle rule

Checks that string literals are not used with == or !=.
Modify MethodLength checkstyle rule

Revert blocks to check to the default tokens (METHOD_DEF, CTOR_DEF)
Modify ParameterNumber checkstyle rule

- Increase maximum allowable number of parameters from default (7) to 10
- Make declarations to check	apply only to METHOD_DEF
Enable GenericWhitespace checkstyle rule

Checks that string literals are not used with == or !=.
Modify WhitespaceAround checkstyle rule

Enable allowEmptyConstructors and allowEmptyMethods
Modify ConstantName checkstyle rule

Allow for logger variable to be defined without adhering to normal
constant naming restrictions.
Modify NewlineAtEndOfFile checkstyle rule

Only accept Unix line separator.
Enable custom RegexpMultiline checkstlye rule

Enforce Unix line endings.
Enable custom RegexpSinglelineJava checkstlye rule

Enforce that there are no calls to System.out.* and System.err.*
