acid: Rework build log records

Two new pieces of metadata are now included in a job record: the git
commit hash, and an indicator of the job execution reason (aka: push
event, or periodic maintenance).

The job records themselves are converted into directories containing
files which define these metadata.  Previously, all metadata was packed
(underscore-delimited) into the log filename.

The indication of job PASS/FAIL is no longer given by a line of text
appended to the log.  Instead, a file named 'fail' will exist in the
directories of failed jobs.

The semantics of the status file are further defined by this patch as
well.  The file will contain:

    "": when the system is idle
    "maint": when maintenance is in progress (inbetween jobs)
    a job number: when a job is in progress

and the file will _always_ exist.
