Brad King 27141eede7 Modules: Rename FindXerces to FindXercesC
The FindXerces module was added in commit v3.1.0-rc1~155^2 (FindXerces:
New module to find Apache Xerces-C++, 2014-08-17).  However, there are
two implementations of Xerces, one in C++:

  http://xerces.apache.org/xerces-c/

and one in Java:

  http://xerces.apache.org/xerces-j/

Rename FindXerces to FindXercesC to clarify that it is about the C++
implementation.

While at it, add the missing CMake 3.1 release note about this module.

# FindXercesC
# -----------
#
# Find the Apache Xerces-C++ validating XML parser headers and libraries.
#
# This module reports information about the Xerces installation in
# several variables. General variables::
#
# XercesC_FOUND - true if the Xerces headers and libraries were found
# XercesC_VERSION - Xerces release version
# XercesC_INCLUDE_DIRS - the directory containing the Xerces headers
# XercesC_LIBRARIES - Xerces libraries to be linked
#
# The following cache variables may also be set::
#
# XercesC_INCLUDE_DIR - the directory containing the Xerces headers
# XercesC_LIBRARY - the Xerces library
