o Minor features (developer tools):
- Add a check_cocci_parse.sh script that checks that new code
is parseable by Coccinelle. Add an exceptions file for unparseable
files. Closes ticket 31919.
- Call the check_cocci_parse.sh script from a 'check-cocci' Makefile
target. Closes ticket 31919.
o Minor features (git scripts):
- Call the check_cocci_parse.sh script from the git commit and push hooks.
Closes ticket 31919.
- Skip unmodified source files when doing some existing git hook checks.
Related to ticket 31919.
o Minor features (continuous integration):
- Call the check_cocci_parse.sh script from Travis CI. Closes ticket 31919.
