NDK r20 provides a declaration of android_get_device_api_level() at API level

crashpad's definition, so stop defining it if the NDK is new enough.

client_win used a non-standard/poorly defined "Acquire Store" and
"Release Load" pair to have handlers notify when they changed
state and to wait for handlers to change state. Acquire stores
and Release Loads are not expressable in C++11 atomics and even at
face value did not provide useful semantics here (code waiting for a
handler to change state wants to see the handler's stores.)

Most Crashpad builds use Microsoft's armasm64.exe macro assembler
for .asm source files. When building in Chromium, clang-cl is used
as the assembler instead. Since the two assemblers recognize different
assembly dialects, the same .asm file can't be used for each.
As a workaround, use a prebuilt .obj file when the Microsoft-dialect
assembler isn't available.
The obj file is generated from the capture_context_win_arm64.asm
by armasm64 macro assembler. If this asm file is modified,
the obj file needs to be updated.

the handler's current normal mode is to dump a single process and exit.
This change ensures the upload thread has a chance to upload the report

This change should not affect upload on Chrome/WebView/Chromecast which
don't pass Crashpad a --url option and are still responsible for their

This also adds CreateCredentialSocketpair() to create a pair of

to avoid race conditions in properly setting credentials.
Also update the handler to use Strategy::kNoPtrace (which causes the
