If attaching to a target that is already running JLinkGDBServer calls
RTOS_GetNumThreads() without a prior call to RTOS_UpdateThreads(). So
do this within RTOS_GetNumThreads() if g_plugin_priv.ntcb has not yet
been initialized.
Note: If after attaching the debugger to the target, the target is
resumed and then stopped again, the RTOS_UpdateThreads is actually
called. Thus, we are not running on stale thread data in this case.
I also changed PLUGIN_VER to API_VER and its value to 101, as
RTOS_GetVersion() does not query the version of the plugin, but the API
version implemented by the plugin, which in our case is 1.1.

The packed-attribute on the tcb_info_s type was misplaced, which caused
incompatible memory layout between host and target. According to
current GCC documentation:
> You may specify type attributes in an enum, struct or union type
> declaration or definition by placing them immediately after the struct,
> union or enum keyword. You can also place them just past the closing
> curly brace of the definition, but this is less preferred because
> logically the type should be fully defined at the closing brace.
I also added jlink-nuttx.so to the .gitignore list and updated nxstyle
to ignore the camel case function names required by JLinkGDBServer.

Use `JLinkGDBServer -rtos libnuttxplugin` to add this plugin.
Then in gdb can use command:
- `info threads` to show all threads infos
- `thread (id) ` to switch thread.
- `bt` to show thread backtrace.
