Many scripts compare actual and expected output using
"diff -u". This is nicer than "cmp" because the output shows
how the two differ. However, not all versions of diff
understand -u, leading to unnecessary test failure.
This adds a test_cmp function to the test scripts and
switches all "diff -u" invocations to use it. The function
uses the contents of "$GIT_TEST_CMP" to compare its
arguments; the default is "diff -u".
On systems with a less-capable diff, you can do:
GIT_TEST_CMP=cmp make test

t6029 already checks if subtree available and works like recursive. This
patch adds code to test test the extra functionality the subtree merge
strategy provides.

An earlier commit e1b3a2c (Build-in merge-recursive) made the
subtree merge strategy backend unavailable. This resurrects
it.
A new test t6029 currently only tests the strategy is available,
but it should be enhanced to check the real "subtree" case.
