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'))

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.

1b2f448720 Fuchsia: de-port generate_dump
generate_dump is not being used on Fuchsia (because only the system-reporter
version of Fuchsia Crashpad is actively used).

GetProcessFromKoid() is becoming increasingly difficult to implement, so simply
de-port generate_dump until we actually need it again in the future (if ever).

Removes GetRootJob().

f5d5a41317 fuchsia: Add implementation of ScopedTaskSuspend
This implementation has some limitations as documented in the header,
however, threads must be suspended in order to use the register capture
debug API so this is somewhat useful for now in the context of
generate_dump.

Also, refactor some child-object retrieval helpers used in a few places.

00e6bd0887 fuchsia: Get 'all' to build
Adds a zlib build file for when building standalone (rather than reusing
Chromium's, though the code still Chromium's patched copy). The separate
build file avoids including the code for minizip and other support
targets (instead, only the main libzlib.a static_library is defined).
The other libraries and executables won't build in the Crashpad repo, so
having a local build file means that all targets defined in the GN build
are buildable.

generate_dump is passing an invalid handle to ProcessSnapshotFuchsia as
there's not yet any utility to convert a pid to a handle. But that's no
great loss, because ProcessSnapshotFuchsia doesn't do anything itself
yet.

281be63d00 Standardize on static constexpr for arrays when possible
This uses “static” at function scope to avoid making local copies, even
in cases where the compiler can’t see that the local copy is
unnecessary. “constexpr” adds additional safety in that it prevents
global state from being initialized from any runtime dependencies, which
would be undesirable.

At namespace scope, “constexpr” is also used where appropriate.

For the most part, this was a mechanical transformation for things
matching '(^| )const [^=]*\['.

Similar transformations could be applied to non-arrays in some cases,
but there’s limited practical impact in most non-array cases relative to
arrays, there are far more use sites, and much more manual intervention
would be required.

5a21de6a1b win: Retrieve thread context for x64
Retrieve context and save to thread context. NtQueryInformationThread
is no longer required (right now?) because to retrieve the CONTEXT, the
thread needs to be Suspend/ResumeThread'd anyway, and the return value
of SuspendThread is the previous SuspendCount.

I haven't handle the x86 case yet -- that would ideally be via
Wow64GetThreadContext (I think) but unfortunately that's Vista+, so I'll
likely need to to a bit of fiddling to get that sorted out. (It's actually
likely going to be NtQueryInformationThread again, but one thing at a
time for now.)
