acs_common.h has unneeded defines TEST_NAME and TEST_NAME_HELPER

[cdwilde]

In val/common/include/acs_common.h, there is a generic define:

#define TEST_NAME_HELPER(x,y) c##x##y
#define TEST_NAME(x,y) TEST_NAME_HELPER(x,y)

Grepping through the ACS database, I don't see it used anywhere.

We ran into a problem where it conflicted with something local.

Can we either remove it (since it isn't used) or change it to BSA_TEST_NAME_HELPER and BSA_TEST_NAME?
