[rfc target-side break conditions 0/5 v2] General info

[Luis Gustavo]

Hi,

This is an updated series of patches to implement target-side breakpoint 
condition evaluation.

Most of the changes are in part 1, 3 and 5. The other parts had only 
minor changes.

The current testsuite seems to be a good exercise for this feature when 
ran in gdbserver mode. I can provide additional tests if required.

Part 1: Documentation bits
Part 2: Protocol and feature changes
Part 3: GDB-specific changes
Part 4: GDBServer tracepoint/agent expression common code cleanup
Part 5: GDBServer breakpoint condition evaluation enablement

Luis
