Avoid using vec_del1() for directory vector to keep indexes valid all
the time.
There are state counters for each slave in LACP bond mode which can be
dynamically created and removed. Vector index is used to access these
counters. But also vec_del1() is used to remove counter from vector.
This function changes the index of the last element, so after this we
are unable to access ex-last element using old index.
As a result it is not possible to add-del-add two interfaces to the LACP
bond:
DBGvpp# create bond mode lacp
BondEthernet0
DBGvpp# create packet-generator interface pg1
DBGvpp# create packet-generator interface pg2
DBGvpp# bond add BondEthernet0 pg1
DBGvpp# bond add BondEthernet0 pg2
DBGvpp# bond del pg1
DBGvpp# bond del pg2
DBGvpp# bond add BondEthernet0 pg1
DBGvpp# bond add BondEthernet0 pg2
bond add: /if/lacp/1/3/partner-state is already register

The current code only allowed access to the main thread error counters.
That is not so useful for a multi worker instance.
No return a vector indexed by thread of counter_t values.

Split the stat_segment.c code from stats.c.
Rename stats.[ch] to prepare for removing (19.01?)
In addition stats.api can be removed.
Since the stats aggregation for the stat segment does not use the API, that
part is now done on the main thread. (Old stats aggregator is also left in place).

Put error counters under node_index.
/err/<node-name>/<error-name>
E.g:
/err/ip4-lookup/Hash table collisions
/err/ip6-rewrite/Buffer allocation error
Error names are not globally unique, and this allows
for walking all errors for a particular node.
Put interface counters under the directory /if.
E.g. /if/rx
Put system counters under the directory /sys.
E.g. /sys/vector_rate

- Interactive commands like "ping" read extra input from the
input stream.
- In the case of "ping" it is simply a signal to cease the current
operation.
- "vppctl", in non-interactive mode, will issue a "quit" immediately
after the requested command to queue up closing of the session.
- This resulted in "ping" thinking a keypress was seen and returning
control to the CLI; the "quit" command however is consumed by the
keypress event handler and thus the session does not close.
- This patch reworks vppctl slightly to only issue "quit" after the
command has completed. In particular it uses the fact that VPP issues
NUL bytes as a surrogate prompt between output of commands to signal
acknowledgement that the command has completed; vppctl now flags
that the quit should be issued after the next such acknowledgement.
- Since input it still accepted, the user can still terminate the
"ping" early, if desired.

Short version: Make vppctl behave as expected when run
from scripts, or without a controlling terminal, and
especially when using it with VPP commands on its
command line ("non-interactively").
In particular, prevent the welcome banner and VPP CLI
prompt from being sent by VPP when being used in these
ways.
vppctl
------
- Improve vppctl's detection of non-interactive sessions.
- Pass non-interactiveness in the terminal type telnet option
as a value distinct from "dumb" (which means non-ANSI capable.)
- Make tty setup handling more robust.
- Only send non-interactive command once we've sent the
terminal type, to ensure correct event sequence; we need
the VPP cli session to be in line-by-line mode.
- Ignore stdin when it looks something like /dev/null.
- Skip NUL bytes received from VPP.
VPP CLI
-------
- Detect "non-interactive" terminal types and set session
parameters accordingly.
- Add an "interactive" flag that controls whether the welcome
banner and CLI prompt are sent.
- Detect if telnet options processing switched us into line
mode and act accordingly for the rest of the current input
buffer. This was causing the command string to be echoed
by the CLI editor code.
- For non-interactive sessions, send a NUL byte after the
input buffer has been processed. This is because vppctl
depends on seeing traffic before it will try to close the
session; a command with no output would cause it to hang.
NUL bytes are ignored by all decent terminals, but we have
vppctl strip them out anyway.
- Prevent certain commands from running in non-interactive
sessions since they manipulate interactive-related features.
- For interactive sessions, quench the prompt that prints on
VPP shutdown.
- Detect and handle socket errors in the CLI; sessions were
leaking.
- Pevent SIGPIPE from ever being raised; handle EPIPE instead.
We don't need VPP to die just because a socket closed just
before we try to write to it!
- Add a command to dump a list of current CLI sessions; mostly
this was to detect session leakage, but it may have some
general utility.

In the CLI parsing, below is a common pattern:
/* Get a line of input. */
if (!unformat_user (input, unformat_line_input, line_input))
return 0;
while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT)
{
if (unformat (line_input, "x"))
x = 1;
:
else
return clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
}
unformat_free (line_input);
The 'else' returns if an unknown string is encountered. There a memory
leak because the 'unformat_free(line_input)' is not called. There is a
large number of instances of this pattern.
Replaced the previous pattern with:
/* Get a line of input. */
if (!unformat_user (input, unformat_line_input, line_input))
return 0;
while (unformat_check_input (line_input) != UNFORMAT_END_OF_INPUT)
{
if (unformat (line_input, "x"))
x = 1;
:
else
{
error = clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
goto done:
}
}
/* ...Remaining code... */
done:
unformat_free (line_input);
return error;
}
In multiple files, 'unformat_free (line_input);' was never called, so
there was a memory leak whether an invalid string was entered or not.
Also, there were multiple instance where:
error = clib_error_return (0, "unknown input `%U'",
format_unformat_error, line_input);
used 'input' as the last parameter instead of 'line_input'. The result
is that output did not contain the substring in error, instead just an
empty string. Fixed all of those as well.
There are a lot of file, and very mind numbing work, so tried to keep
it to a pattern to avoid mistakes.
