[oe] Bug in cooker - networked PR_SERV

[Jan-Simon Möller]

Hi !

I found a bug in cooker that shows up when I try to enable the networked 
PRSERV. bitbake will crash (and still run at 100% after CTRL-C) until kill -9.

I tracked it down to bitbake/lib/bb/cooker.py line 169:
        if self.state != state.initial:
            raise Exception("Illegal state for feature set change")

self.state seems to be 6 at this stage and state.initial is 0 .

Hack: If I comment out this check, it seems to continue, but I see no size-
increase in the prserv sqlite and also nothing printed for loglevel=DEBUG in 
the log. 


Here are the details:

My setup is:
Build Configuration:
BB_VERSION        = "1.24.0"
BUILD_SYS         = "x86_64-linux"
NATIVELSBSTRING   = "openSUSE-project-13.2"
TARGET_SYS        = "i586-poky-linux"
MACHINE           = "qemux86"
DISTRO            = "poky"
DISTRO_VERSION    = "1.7.1"
TUNE_FEATURES     = "m32 i586"
TARGET_FPU        = ""
meta              
meta-yocto        
meta-yocto-bsp    = "<unknown>:<unknown>"

####### Only changes to conf/local.conf:
PRSERV_HOST="127.0.0.1:5555"
(an a prserv started in a separate terminal)

####### Crash
