pr_overlap.py took every added line with APS5_VABI before a name and a
parenthesis as an export, so a declaration such as
extern "C" int* APS5_VABI __error_nid_postfix(); made each pull request
that adds it "implement the same function" as all the others. A line
that ends in a semicolon is a declaration and is skipped; every
definition's first line in the tree ends in a brace, a parenthesis or
a comma.
Registers pr_overlap_exports.
