Add VTY command
line vty
bind A.B.C.D
The command merely stores the configured IP-address, which can then be used by
the calling main program to set the telnet port of the VTY line. (Commits in
openbsc and osmo-iuh will follow up on this.)
Add function vty_get_bind_addr() to publish the address in the vty.h API.
Add static vty_bind_addr to store.
For allocation/freeing reasons, a NULL address defaults to 127.0.0.1.
BTW, I decided against allowing keywords 'any' and 'localhost' in place of an
actual IP address to make sure a written config is always identical to the
parsed config.
'\0' gets translated to zero but the argument to vector_set is
a pointer and it gets converted to a pointer.

Shipping our own private copy of talloc was a good idea in 2008,
when it was not readily available on most target platforms. Today,
the situation is quite different, as it is a standard library on
major Linux distributions.
Currently there is only the 'show stats' command which shows all
counter and stat_item values. This can lead to many lines of output
if there are per-subscriber rate counters.
The new command added by this commit allows it to only show groups of
a certain level (class_id), similar to the 'level' configuration
command for stats reporter.
The new command is
show stats level (global|peer|subscriber)

For the atoi we need to pass the val as a string. This means
we need to write "0" which then gets parsed to 0.
[src/vty/stats_vty.c:90]: (error) Possible null pointer dereference: val
This commit adds class_id fields to the rate_ctr and stat_item group
descriptions. The stats reporter code is extended to only process
groups whose class_id does not exceed a per reporter max_class level.
If the class_id is not set, the code assumes 'global' for groups with
idx == 0 and 'subscriber' otherwise.
The following vty command is added to config-stats:
level (global|peer|subscriber) Set the maximum group level

Since the the stat_item and stats functions and data types are meant
to be exported, they get an osmo_ prefix.

This reporter passes the measurement values to the logging subsystem

To support reporters without network configuration, this commit
introduces the have_net_config flag to provide corresponding error

If the MTU is given, combine several messages into a single UDP
packet until the limit is reached. Flush all reporters after the
values have been scanned.
New vty commands (node config-stats):
mtu <100-65535> Enable multi-metric packets and set the maximum
packet size (in byte)
no mtu Disable multi-metric packets
Note that single messages that are longer than the given MTU (minus
28 octets protocol overhead) will be dropped.

This calls stats_flush in regular intervals which polls the
statistical values and calls the active reporters when values have
changed.

This commit provides stats configuration similar to the log
configuration.
The following vty commands are added to the config node:
stats reporter statsd Create/Modify a statsd reporter
no stats reporter statsd Remove a statsd reporter
To actually configure a reporter, the config-stats node is entered
when the "stats reporter" command has succeeded. The following new
vty commands are available there:
local-ip ADDR Set the IP address to which we bind locally
no local-ip Do not bind to a certain IP address
remote-ip ADDR Set the remote IP address to which we connect
remote-port <1-65535> Set the remote port to which we connect
prefix PREFIX Set the item/counter name prefix
no prefix Do not use a prefix
enable Enable the reporter
disable Disable the reporter

This file will contain the VTY code related to statistics.
This commit adds a minimal file with just as single VTY command:
- show stats This command shows all statistical values
To enable this and future commands, the main program needs to call
stats_vty_add_cmds().

Currently the groups for stat_items and counter are iterated
manually.
This commit makes use of the new iterator functions to access the
single elements via handlers.

We are mixing enums and hope that no short-enums are used. This
is leading to a lot compiler warnings generated by clang. Change
the API to work with integers.
Porting:
The go_parent_cb implementations in the applications need to be
fixed. The API change leads to a compile time warning.

We want to see from which category/subsystem a certain log message
is coming from and use a different timestamp format as well. Add
two new bitfields. This doesn't change the size of the structure
and on 32bit we still have 27bits left.
The extended timestamp will take preference over the current and
default timestamp format.
Fixes: SYS#602
For the BSC/NITB application we see that people modify the band
without modifying the ARFCN. This creates an unbootable config.
Using the new hook the BSC/NITB can check if the config is
consistent and prevent the config file being written.

the bits/crc files are not inside the sourcedirectory but will end
in the build directory. Go and look there as well. This somehow
doesn't fail with make distcheck but when building for Yocto Dizzy.
If the read callback closes the connection conn is already freed so we
can't derefernce it. Instead return -EBADFD in the read function if it
closed the connection and check for that.
The testcase didn't work on Ubuntu 12.04 because vty_create will
directly call vty_event (e.g. not through the plt). This means
that the approach to override vty_event in the testcase failed.
Use the signal interface of libosmocore and make the testcase
use it. The signals can be generally useful as well.
This patch removes an assertion of node > CONFIG_NODE and changes
the function to handle all nodes properly.
For the sake of completeness, the generic 'exit' command
implementation is extended to work properly with all nodes, too.
This adds the vty_install_default() function that is basically the
install_default() function plus the registration of the commands
'exit' and 'end'. The latter is only provided in subnodes of
ENABLED_NODE and CONFIG_NONE.
The VTY test program is extended to check these commands.
Ticket: OW#952
Compiled with ubuntu 1204 (precise), where -Wformat-security is enabled by
-Wall.
Test yields ok, but the current implementation doesn't properly support
multi-character separators and end strings. So the test output is truncated.
