[PATCH 0/5] Coalesce/aggregate (async) vCont packets/actions

[Pedro Alves <palves@redhat.com>]

Since:

 [PATCH 00/18] Remote all-stop on top of non-stop
 https://www.sourceware.org/ml/gdb-patches/2015-10/msg00213.html

The remote target supports "maint set target-non-stop on".  However
that's still not the default.

I thought I'd first try to aggregate vCont packets, because with 
"maint set target-non-stop on", we go from:

- All-stop / "maint set target-non-stop off"

 (gdb) c
 Continuing.
 (...)
 Sending packet: $vCont;c#a8..

to:

- All-stop / "maint set target-non-stop on"

 (gdb) c
 Continuing.
 (...)
 Sending packet: $vCont;c:p2c45.2c45#7c...Packet received: OK
 Sending packet: $vCont;c:p2c45.2c4f#ad...Packet received: OK
 Sending packet: $vCont;c:p2c45.2c50#78...Packet received: OK
 ... one packet per thread ...

After the series, we'll get back:

 (gdb) c
 Continuing.
 (...)
 Sending packet: $vCont;c#a8...Packet received: OK

(Note the "OK", showing that that was indeed an async vCont resume.)

along with other "wildcard" vCont packets like, "vCont;s:p1.1;c".

Also pushed to the users/palves/vcont-coalesce-actions branch.
