Andreas Fritiofson 517ba0690d Clean up const usage to avoid excessive casting
Don't use const on pointers that hold heap allocated data, because that
means functions that free them must cast away the const.

Do use const on pointer parameters or fields that needn't be modified.

Remove pointer casts that are no longer needed after fixing the constness.

Anton Kolesov b8a23f1c43 gdb_server: Do not set gdb_con->sync to true for new connections
In GDB connected to OpenOCD there is a command "monitor gdb_sync" which makes
next stepi command to be ignored while GDB still will get an updated target
state. This command sets gdb_connection->sync field to true to notify that stepi
should be ignored. This field is set to true for all new connection and is set
to false after first "continue" command. However if first resume command is
stepi/nexti then it will be ignored and result will confuse GDB client, it will
report that target received signal SIGINT. This patch sets this field to false
for new connections, thus stepi/nexti will work properly when it is a first
resume command.

Hsiangkai Wang 0961987a19 gdb_server: check target before executing event callback
As debugging multi-targets, every target has its own gdb connection.
If there are two connections, gdb_target_callback_event_handler will
be registered twice.  Everytime event occurs, the registered callback
will be executed twice.  If both targets are running, as user issues
ctrl-c in one gdb client, both connections will send "stop reply" to
GDB clients even TARGET_EVENT_GDB_HALT is caused by one of them.

The commit fix above problem as debugging multi-targets.

Hsiangkai Wang 0a4c8990c2 gdb_server: support File-I/O Remote Protocol Extension
The File I/O remote protocol extension allows the target to use the
host's file system and console I/O to perform various system calls.

To use the function, targets need to prepare two callback functions:
* get_gdb_finish_info: to get file I/O parameters from target
* gdb_fileio_end: pass file I/O response to target

As target is halted, gdb_server will try to get file-I/O information
from target through target_get_gdb_fileio_info(). If the callback function
returns ERROR_OK, gdb_server will initiate a file-I/O request to gdb.
After gdb finishes system call, gdb will pass response of the system call
to target through target_gdb_fileio_end() and continue to run(continue or step).

To implement the function, I add a new data structure in struct target,
called struct gdb_fileio_info, to record file I/O name and parameters.

Details refer to GDB manual "File-I/O Remote Protocol Extension"

Hsiangkai Wang 80d412bafc gdb server: new feature, add stop reason in stop reply packet for gdb
In GDB remote serial protocol, the stop reply packet could contain more
detail stop reason. The currently defined stop reasons are listed below.

* watch
* rwatch
* awatch
* library
* replaylog

This commit adds stop reason, watch/rwatch/awatch, in stop reply packet for
just hit watchpoint. As manual indicates, at most one stop reason should be present.

The function needs target to implement new hook, hit_watchpoint. The hook will fill
the hit watchpoint in second parameter. The information will assist gdb to locate
the watchpoint. If no such information, gdb needs to scan all watchpoints by itself.

Refer to GDB Manual, D.3 Stop Reply Packets

in gdb event callback.  It will execute event statements in config
files twice.

The calculation for reg_packet_size in gdb_get_registers_packet() could
generate a wrong result in the case of multiple registers whose size is
not a multiple of 8.

The current calculation sums the sizes for all registers then rounds the result
up to the next multiple of 8.

Instead it should round each register size up individually and sum the results for all registers.

The code changes are *reasonably* clean, but perhaps it could be
made a bit more elegant, but I didn't want to change things after
I finished diagnosis/testing & submitting the patch.

The problem was that logging can send the text and the newline
separately in two different requests and the telnet code would
incorrectly remove the prompt from the end of a line.

This addresses what would otherwise be something of a functional
regression.  An earlier version of the interface had a dangerous
problem:  it would silently erase data outside the range it was
told to erase.  Fixing that bug turned up some folk who relied on
that unsafe behavior.  (The classic problem with interface bugs!)
Now they can get that behavior again.  If they really need it,
just specify "pad".

Øyvind Harboe 3e33393078 gdbserver: fix typo that broke read/write watchpoint
It looks like a bugfix from normal breakpoints was not
copied over.

Do not use clever mathematics and assumptions to convert from
GDB enum for break/watchpoints to OpenOCD enum.

Drop connection upon unknown breakpoint type, this code path
was not really considered by the previous code I think.

David Brownell 8c730aaee2 Doxygen file comments
Add file comments to a few files.  Make the GDB server use
more conventional (pointer-free) hex digit conversion.
