commit ea77280ec5c1681c65601030e0bab09126c10c3c
Author: Evgeniy Naydanov <evgeniy.nayda...@syntacore.com>

target: clean-up target configuration argument handling
There were multiple issues with how `target create` and `<target_name>
configure/cget` used to handle arguments:
* `Jim_WrongNumArgs()` called with `argc == 0`, which causes a
`JimPanic` if `JIM_DEBUG_PANIC` is defined
Link:
https://github.com/msteveb/jimtcl/blob/3a2cfdf696daa0d92c0f2e8d8fc1ff337ba99c62/jim.c#L11934
* In some cases `Jim_WrongNumArgs()` reported unhelpfull arguments
making the message incorrect, e.g:
```
> openocd -c 'target create a_name'
...
wrong # args: should be "a_name <name> <target_type> [<target_options> ...]"
```
Here the error message mentions both: the name of the target passed to
`target create` (`a_name`) and `<name>`.
To combat these issues a new function is introduced:
`jim_getopt_wrong_num_args()`. The function wraps the call to
`Jim_WrongNumArgs()` making these kinds of errors less likely.
