symbol version for newly added functions in libc

[Hajimu UMEMOTO]

Hi,

I'm working on update our stub resolver in libc to the final version
of libbind.
This update adds some new functions.
I see that FBSD_1.4 should be used for 11.0-CURRENT.  However, I have
a plan to do MFC into 10 and 9.  In this case, which symbol version
should be used for new functions FBSD_1.2, FBSD_1.3 or FBSD_1.4?

Sincerely,
