As in the previous patch, return TRUE if the debug event should be
ignored or FALSE is we should tell gdb. There's no need to have an
in_trap context member for that.

It was returning a mix of TRUE/FALSE and in some cases DBG_CONTINUE.
Let's return TRUE if the exception has been handled and should be
ignored, or FALSE if not and if we should notify gdb.

This reports the full register sets to gdb, telling it about custom
offsets and sizes. It will make the gdb specific register length not
required anymore.
We also have to report architecture specific vector types and flags
that are normally builtin in gdb as it does not load them anymore when
custom register set is reported.
This makes gdb stop using its incorrect heuristics and actually request
the library list, it now correctly gets PE modules information and is
able to correctly use debug info from mixed modules.

As we don't report fork/vfork/exec events, this allows gdb to request

For now gdb does not request it as it still believes it's running a
normal application. It will however, as soon as we advertise support for
qXfer:features:read request and reply with a custom register set.
This also introduces packet_reply_open_xfer / packet_reply_close_xfer
function to allow partial replies. It always allocate the full reply
for simplicity and then truncates to the requested offset and size.

The vCont handler used some overcomplicated logic, we only need to
iterate over the actions and apply them on the matching threads that
didn't match yet.
Thanks to DBG_REPLY_LATER we can now continue/step any thread regardless
of whether it is the one that raised the debug event. Just suspend all
active threads after debug event is raised and resume them one by one,
according to the gdb request. If the thread that raised the debug event
should not be resumed, reply with DBG_REPLY_LATER.

This is still some cleanup, and does not fix much wrt step / continue,
but it introduces dbg_thread_set_single_step that is going to be useful
for individual thread control and let us remove all remaining uses of
gdbctx->context.

This was using some conditional context read and dbg_curr_thread checks,
we can just read the context of the selected thread and write it back as
needed.
Also, packet_reply_register_hex_to was using gdbctx->context, which is
not always the context we want to read.
We still need to keep changes in sync with gdbctx->context as it may be
still be used for step / continue, but step / continue doesn't work well
and we will rewrite it later.

Sometimes multiple packets are received and we were assuming it was
some repeated requests due to slow ack. We can ack packets first.
It was also dropping some perfectly valid packets and we should process
them all. For instance, lldb frontend sometimes send multiple packets
at a the same time and expects them to be handled.
