Bill Thorp 0f662b8e38 sql based tally (#1166)
* WIP

* wacky changes

* more

* it builds.... IT BUILDS!!!

* fixed SQL, broke out saving tallies for testing

* shorter lines

* fixed SQL, moved tally_test to testplanet

* lint

* WIP logic error preventing PUT and GETs to same serialnum

* fixed BWA test

* fixed temporary brain failure

* eliminated magic numbers

* cleaned up satellite uplink stats

* use errs.Combine instead

* thrashing

* fixed tally erroneous error msg

* fixed tally test

* lint

* SQL syntax attempt to fix

* spelling error

* made bwa db test resist old postgres data

* postgres pk error msg hunting

* postgres pk error msg hunting

* postgres

* err might be nil?

* fixed error logging bug

* hopefully solved postgres issue

* using rebind

* moved tests to _test package

* fixing test dirs

* finally made sense of Egons package name feedback

* UTC, array fixes
