[PATCH/7.10 0/2] gdbserver: Fix several fork support (& co) issues

[Pedro Alves <palves@redhat.com>]

In the "[PATCH 3/N] remote follow fork and spurious child stops in
non-stop mode" thread:

 https://sourceware.org/ml/gdb-patches/2015-07/msg00868.html

several issues were identified in the new gdbserver follow fork
support in 7.10.  This addresses all I found.  I'm thinking these are
7.10 worthy.

The test added exposes issues in gdb's native target, but I won't have
time to address them myself right now, so the test is kfailed there.
