Peter Boström 1aa478d161 Remove DISALLOW_* macros in crashpad 
This change was partially scripted and partially done manually with vim
regex + manually placing the deleted constructors.

The script change looked for destructors in the public: section of a
class, if that existed the deleted constructors would go before the
destructor.

For manual placement I looked for any constructor in the public: section
of the corresponding class. If there wasn't one, then it would ideally
have gone as the first entry except below enums, classes and typedefs.
This may not have been perfect, but is hopefully good enough. Fingers
crossed.

#include "base/macros.h" is removed from files that don't use
ignore_result, which is the only other thing defined in base/macros.h.
