[PATCH XTS] tet: tet_getvar needs to take a const char* argument

[Aaron Plattner]

config.c: In function ‘initconfig’:
config.c:394: error: passing argument 1 of ‘_initconfig’ from incompatible pointer type
config.c:328: note: expected ‘char * (*)(const char *)’ but argument is of type ‘char * (*)(char *)’

I'm thinking of making a release after this patch, with the current version
number 0.99.0 even though there are a ton of warning fixes we can still
make and a lot of the tests are expected to fail.  The reason is that some
people are actually getting serious about running XTS and I want to give
them a tagged release version they can use as a baseline.

Let me know if you have objections, concerns, or changes that you think
should go in first.
