Mark Mentovai dfe81014f7 Add compat to Crashpad.
compat includes headers providing definitions normally provided by the
system, in cases where the system SDK does not always provide the
correct or up-to-date definitions, and cases where code on different
platforms needs to access definitions normally only available on one
platform.

To provide definitions on a single platform, where the system SDK may
not provide the definitions correctly, use subdirectories named for the
platform, such as “mac”.

To provide definitions normally available on only one platform to
others, use subdirectories that identify that they are to be used on
platforms other than the one that originated their definitions, such as
“non_win”.

In all cases, headers should be named as they are natively in their
respective SDKs, so that it’s possible to #include them according to
their usual names.
