50ed179e9a Use BUILDFLAG for OS checking
Use BUILDFLAG(IS_*) instead of defined(OS_*).

This was generated mostly mechnically by performing the following steps:
 - sed -i '' -E -e 's/defined\(OS_/BUILDFLAG(IS_/g' \
                -e 's%([ !])OS_([A-Z]+)%\1BUILDFLAG(IS_\2)%g' \
       $(git grep -l 'OS_'
         '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
 - sed -i '' -e 's/#ifdef BUILDFLAG(/#if BUILDFLAG(/' \
       $(git grep -l '#ifdef BUILDFLAG('
         '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
 - gsed -i -z -E -e \
       's%(.*)#include "%\1#include "build/buildflag.h"\n#include "%' \
       $(git grep -l 'BUILDFLAG(IS_'
         '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm')
 - Spot checks to move #include "build/buildflag.h" to the correct parts
   of files.
 - sed -i '' -E -e \
       's%^(#include "build/buildflag.h")$%#include "build/build_config.h"\n\1%' \
       $(grep -L '^#include "build/build_config.h"$'
         $(git grep -l 'BUILDFLAG(IS_'
           '**/*.c' '**/*.cc' '**/*.h' '**/*.m' '**/*.mm'))

       grep -v '^#include "build/buildflag.h"$' "${f}" > /tmp/z; \
       cp /tmp/z "${f}"; done
 - git cl format
 - Update mini_chromium to 735143774c5f (intermediate step).
 - Update mini_chromium to f41420eb45fa (as checked in).
 - Update mini_chromium to 6e2f204b4ae1 (as checked in).

For ease of review and inspection, each of these steps is uploaded as a
new patch set in a review series.

This includes an update of mini_chromium to 6e2f204b4ae1:

f41420eb45fa Use BUILDFLAG for OS checking
6e2f204b4ae1 Include what you use: string_util.h uses build_config.h

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.

3965bc7d78 Refactor OS_LINUX usage for coming LaCrOs update.
We're working to decouple ChromeOS and Linux builds of Chrome.

Currently OS_CHROMEOS sets OS_LINUX, so we need to refactor
current OS_LINUX usage to make this explicit.

More information can be found at go/cros_is_linux_os_linux

59cdfbb031 linux: support multi client sockets in ExceptionHandlerServer
Multi client socket connections allow multiple clients to request crash
dumps from a handler process using a single, shared socket connection.

This connection mode does not support using a broker process which
requires a dedicated socket connection to ensure handler messages
aren't intercepted by the wrong clients.

The handler uses SIGCONT to indicate to the crasher when a crash dump
is complete (or has failed) and may continue.

c31a86a340 linux: Identify requesting threads
When a crashing process is in a different PID namespace than the
handler, the crasher doesn't have a way of knowing its own thread ID in
the handler's namespace and the kernel lacks mechanisms to perform this
translation before Linux 4.1 (where the information is present in
/proc/<pid>/status:NSPid).

This patch gives the handler a way of identifying the requesting thread
by sending a stack address along with the crash dump request, which
the handler can search for in each of the process' threads.

This information is useful both for attaching exception information
to the right thread and to allow the handler to send signals to the
correct thread when using a shared socket connection.

d1e6a2130d android/linux: add a client interface to control sanitization
Sanitization is controlled by a SanitizationInformation struct to be
read from the client's memory. The address of this struct is either
passed in a ClientInformation when the client requests a crash dump,
or as a flag to the handler --sanitization_information.
