bitbake: codeparser: Add support for correct linenumbers
Currently, if there is something like a python indentation error in a python function, the linenumbers and even file aren't reported correctly. This allows lineno and filename parameters to be passed in to correct this. The lack of a lineno parameter to python's compile() function is worked around by using empty linefeeds. Ugly, but effective and with minimal performance overhead. (Bitbake rev: 5796ed550d127853808f38257f8dcc8c1cf59342) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
