Update a few tests that used to use GIT_CURL_VERBOSE to use the
newer GIT_TRACE_CURL.

"git symbolic-ref -d HEAD" happily removes the symbolic ref, but

Having a submodule whose ".git" repository is somehow corrupt
caused a few commands that recurse into submodules loop forever.

The test framework left the number of tests and success/failure
count in the t/test-results directory, keyed by the name of the
test script plus the process ID.  The latter however turned out not
to serve any useful purpose.  The process ID part of the filename
has been removed.

Add a parameter for the struct checkout variable to check_updates()
instead of using a static global variable.  Passing it explicitly makes
object ownership and usage more easily apparent.  And we get rid of a
static variable; those can be problematic in library-like code.

The fourth argument of strbuf_splice() is passed to memcpy(3), which is
not supposed to handle NULL pointers.  Let's be extra careful and use a
valid empty string instead.  It even shortens the source code. :)
