[bpf-next PATCH v2 0/5] selftests/bpf: Migrate test_tcpbpf_user to be a part of test_progs framework

[Alexander Duyck <alexander.duyck@gmail.com>]

Move the test functionality from test_tcpbpf_user into the test_progs
framework so that it will be run any time the test_progs framework is run.
This will help to prevent future test escapes as the individual tests, such
as test_tcpbpf_user, are less likely to be run by developers and CI
tests.

As a part of moving it over the series goes through and updates the code to
make use of the existing APIs included in the test_progs framework. This is
meant to simplify and streamline the test code and avoid duplication of
effort.

v2: Dropped test_tcpbpf_user from .gitignore
    Replaced CHECK_FAIL calls with CHECK calls
    Minimized changes in patch 1 when moving the file
    Updated stg mail command line to display renames in submission
    Added shutdown logic to end of run_test function to guarantee close
    Added patch that replaces the two maps with use of global variables
