Subject: [PATCH] Block signals during RPMTXN_WRITE transactions

This includes (but not limited to) rpmtsRun() during which the accidental
ctrl-c no longer aborts the whole dang thing. This could've of course
been done without all the other recent signal infra too, but now that it's
all neatly (yeah, right...) wrapped inside rpmsq instead of being littered
all over town its nicer to do.
