Rafał Harabień 77481d36d3 ntdll: Allow getting/setting x86_64 context of x86 processes in wine64. 
WoW64 process has two separate contexts:
- x86 context used most of the time (e.g. by application code)
- x86_64 context used by system when it quits x86 emulation and jumps to
  the kernel code
A notable exception are debug registers - their state is shared. Some
debuggers make use of that fact and sets/gets debug registers of x86
processes using x86_64 thread context.

Add support for setting and getting debug registers using x86_64
thread context. Getting other registers is allowed too and will return
values from x86 thread context.

Fixes hardware breakpoints in IDA 7.0 disassembler (x86_64 app) when
debugging x86 (32 bit) applications.

Dmitry Timoshkov 050dc49b38 server: Set error to STATUS_UNSUCCESSFUL when the server fails to queue APC for a thread. 
I've left another case of returning STATUS_PROCESS_IS_TERMINATING since
that's not covered by the tests.

Zebediah Figura 44fc44880f server: Always set the async result when the APC object is destroyed. 
This can happen if the async is terminated while there is no thread to queue
the APC to (as in the relevant test), or if the client dies before getting the
APC, or before transferring the APC results back to the server.

This also fixes a leak of async objects present since 61abc500f5. If a process
dies while accept asyncs are pending, the asyncs will be terminated but will
not find a valid thread to queue the APC to, and thus async_set_result() and
the completion callback are never called.

Rémi Bernon e2a1f00a38 server: Implement DBG_REPLY_LATER handling. 
This flag causes the debug event to be replayed after the target thread
continues. It can be used, after suspending the thread, to resume other
threads and later return to the breaking.

This will help implementing gdb continue/step packets correctly.
