Prior to this commit, if the user defined a custom
PathPatternRequestMatcher.Builder, security auto-configuration would
still set its base path to matcher the dispatcher servlet path.
We need to give the user more control in this situation.
If the user has defined a custom builder bean it should have a name
other than pathPatternRequestMatcherBuilder. This different name is
required to prevent a clash with the @Fallback bean that's defined
by Security's AuthorizationConfiguration. This commit changes the
bean post-processor so that it will only apply to a bean named
pathPatternRequestMatcherBuilder. By using a different name (which
is necessary unless overriding is enabled) to use can take complete
control of the path pattern request matcher builder.
