d0136707a9 Give clang-format its own error category. 
The posix errno values are probably to the best thing to use for
describing parse errors.

This should also fix the mingw build.

Summary:
This patch ensures that the lines of the block comments retain relative
column offsets. In order to do this WhitespaceManager::Changes representing
continuation of block comments keep a pointer on the change representing the
whitespace change before the block comment, and a relative column offset to this
change, so that the correct column can be reconstructed at the end of alignment
process.
