As gdbreplay communicates with GDB, it outputs all the remote
protocol communication it reads from the remotelogfile to stderr.
This patch disables this behavior by default but adds the new
--debug-logging option which turns printing the packets
to stderr on again.
The motivation for this change is to make it possible to use
gdbreplay with TCL tests. Printing the whole remotelog file out
seems to overflow the expect cache wich causes gdbreplay to not
to get the packet its expects and results in going out of sync
with GDB. Other motivation is making communication between GDB
and gdbreplay faster as printing bigger remotelogfile takes
considerable amount of time.

Fix a few outdated or incoherent things in the README:
- Don't mention remote.c nor *-stub.c files as references for the remote
protocol. remote.c is in GDB, not GDBserver, and *-stub.c files don't
exist today. Add a link to the documentation instead.
- In the "server (target) side" section, use `:2345` instead of
`host:2345`. It currently says that using `host:2345` means we would
expect a connection from `host`. That's not what I would expect by
passing a host part here. If I passed `11.22.33.44:2345` as the listen
address, I would expect it to instruct gdbserver to listen only on that
(11.22.33.44) network interface, not to expect a connection from host
`11.22.33.44`. So, remove that part of the sentence.
- Remove the list of supported target, refer to configure.srv instead.
Keeping a list here is bound to lose sync with reality.
- In the cross-compile instructions, I don't think it's necessary to mention
"In a Bourne shell".
- In the cross-compile instructions, I don't know what passing
`your-target-name` to configure does, I don't think it's valid. Use
`make all-gdbserver` as in the instructions just above.

This patch moves gdbserver to the top level.
This patch is as close to a pure move as possible -- gdbserver still
builds its own variant of gnulib and gdbsupport. Changing this will
be done in a separate patch.
[v2] Note that, per Simon's review comment, this patch changes the
tree so that gdbserver is not built for or1k or score. This makes
sense, because there is apparently not actually a gdbserver port here.
[v3] This version of the patch also splits out some configury into a
new file, gdbserver/configure.host, so that the top-level configure
script can simply rely on it in order to decide whether gdbserver
should be built.
[v4] This version adds documentation and removes some unnecessary
top-level dependencies.
[v5] Update docs to mention "make all-gdbserver" and change how
top-level configure decides whether to build gdbserver, switching to a
single, shared script.
Tested by the buildbot.
