Fix compiler errors when using libc++ in verity.

Rename macros min,max and to_bytes.
min and max macros are no longer allowed in c++.
to_bytes conflict with a header function in <locale>.

Fixes compilation errors:
/build/caroline/usr/include/c++/v1/locale:3596:48: error: too many arguments
verity-9999:       provided to function-like macro invocation
