bitbake: codeparser: don't interact with the cache for subshells
Doing so was causing leakage between the execs of the main value and that of the subshell value, and was causing the cached subshell value to be used for the overall variable. At the least this could cause execs contamination between two variables that while differing, run the same subshell. Beyond that, it's possible we could have been using an incomplete cached value of a subshell for that of the main value. Before this, bb_codeparser.dat would change between parses with differing bbfile parse order. After, it does not change. The codeparser cache version is bumped, to ensure we don't use potentially incorrect cached values from previous runs. This should hopefully resolve the difficult-to-reproduce issues we've seen at Mentor Graphics where bitbake emits a script to run a task and misses dependent functions, resulting in 'command not found' failures. This issue has also been mentioned on the oe devel list, where someone hit a case where oe_runmake was missing from a do_install task (IIRC). Adding debug information showed that bitbake's information about the variable dependencies for this task is inaccurate in the failure cases.
