Add a test case for fast tracepoints' locking mechanism
When installing a fast tracepoint, we create a jump pad with a
spin-lock. This way, only one thread can collect a given tracepoint at
any time. This test case checks that this lock actually works as
expected.
This test works by creating a function which overrides the in-process
agent library's gdb_collect function. On start up, GDBserver will ask
GDB with the 'qSymbol' packet about symbols present in the inferior.
GDB will reply with the gdb_agent_gdb_collect function from the test
case instead of the one from the agent.
gdb/testsuite/ChangeLog:
* gdb.trace/ftrace-lock.c: New file.
* gdb.trace/ftrace-lock.exp: New file.
