p5-Function-Parameters: update to 2.001003.

- Fix threaded initialization issue better. This is the same issue
that was fixed in 2.001002, but now we use PL_op_mutex instead of
PL_check_mutex. This has the advantage of also being thread-safe on
v5.14.
2.001002 2017-11-09
- Fix crash when Function::Parameters is loaded at runtime by
multiple threads (a stack overflow due to infinite recursion).
This is arguably a core bug (#132413). The current workaround
employed by Function::Parameters slightly abuses an internal perl
mutex meant for something else (protecting op checkers), but it
fixes the issue on perls v5.16 .. v5.26.
v5.14 doesn't have this API yet, so the workaround is not thread
safe there. It is technically possible to still run into this issue
if two threads initialize Function::Parameters at the exact same
moment (I haven't managed to reproduce this yet, so hopefully it's
unlikely in practice).
It is possible to completely avoid the problem on all versions of
perl and Function::Parameters by making sure the module is loaded
before the first thread is created.
